Roll the wire between blocks to straighten it. airplanes balsa wood bullseye guillows glider jetfire biplane airplane toys streak wind rubber powered sky band planes bundle sunny For whatever reason, I can now increase the windings to 500 with the 10 loop and that thing climbs like a rocket even though I know it has more torque with the shorter loop. BTW, that last version competition version easily thermaled for a local park recreation manager and was lost going straight up. Our best selling motorplane. Or you can cut the balsa to make a separate rudder. Science Olympiad National Supervisor, Aeronautics. balsa It may not rise very high, but it is fun to watch. I considered that to be enough. The cambered wing will help lift the extra weight of the larger prop. Also mark the exact center of the wing and 3/32 on either side of that, as we did before. And more dihedral to provide more roll stability. Push something like a hat pin into the bottom of the stick where you want the hook. Hold the wing close to the fuselage as you work a bit of it clear through the slot. A form board for this wing would be 2 x 5. Flying and Improving Your Guillows Sky Streak. This can cause breakage of the parts. Your email address will not be published. Check the camber. To do this, we apply a knot lubricant. Drop the motor into the lube bag and massage it to coat it with lube. Greater dihedral improves roll stability. great memories, i always thought the propellers were a little too big for the plane, so i modified them with smaller propellers and longer/thinner rubber bands, this made the plane fly a little faster and longer, thanks for the post. balsa guillow mfrpartno Notice that the hook on the propeller shaft goes on the same side of the stick as the wire motor hook at the back end of the stick. Put a tiny bit of light machine oil on the prop shaft and bearing. Make sure it is centered and square. The jar shown above is 4 1/8 diameter. These sets are widely available in toy, hobby and variety stores. Fold the motor and put it in a storage can. Wrap the Ace bandage tightly around the wing, moving outward with each wrap, all the way past the wing tip. balsa guillow airplane You can increase the dihedral. The Sky Streak uses the Guillows D5 propeller, which is 5 in diameter. Make a similar set of marks on the tailplane. http://www.digitalbuddha.co. This weight difference is actually a small percentage of the total airplane weight of 10.1 grams. I suspect it could take more. You can also use a sewing pin, after cutting the head off. The outer wing panel was soaked in water to soften the wood, then it was strapped onto a curved form with an Ace bandage to shape the curve, and allowed to dry. balsa guillow biplane Be sure the opening is facing away from the prop hook. I recommend this as a good place to start: toys flying airplanes jetfire streak balsa rubber sky band wood copter windup bundle powered play sports outdoor (I put marks 5 from the wingtip, not necessary.). balsa guillows gliders jetfire streak guillow schylling pickrightly It will buckle and break if it is forced straight into the slot. 
A figure 8 is hard to fit on a small flying field. powered rubber band ag plane wings truck 
Think of them as fuel that you burn. These marks show where the edges of the 3/16 wide stick should go when the wing is inserted through the slot in the stick. Near the trailing edge, it is almost straight. Continue counting in the same way, One, two, three, four, five, six, seven, eight, nine, TWO, one, two, three, four, five, six, seven, eight, nine, THREE, one, two, three, four, five, six, seven, eight, nine, FOUR, , one, two, three, four, five, six, seven, eight, nine,FIFTEEN. That is fifteen tens, or 150 turns. With the left wingtip down, the plane slips downward to the left. We can also make a rudder with flexible wire hinges. I found that it worked without the glycerin, but like all liquid soaps, it dried out quickly. Mixing in a little glycerin would help. I decided to try bubble soap because it is likely available in many of the places where you would find Guillows toy planes. We want to leave the center 2 of the wing alone for now. I will camber the wings and put in dihedral, as well as add the other modifications before the event. I am continually impressed with Garys devotion to kids and flight and have begun looking again for an indoor venue. First put marks along one edge of the wing 5 in from each tip. You can also slide the wing a bit to the left. Now bend the straight piece out from the circle around a small radius. Contest quality rubber is not as tough as the kit motors, but it can take more turns and store more energy. If you are teaching a class, use a plastic jar full of sand or gravel. See them at the Guillows site here: If you buy them from Guillows online, consider getting a bag of extra motors and 6 props as well. Buy several AMA Cub kits and continue with the AMA Cub Squirrel, the AMA Cub Denny Dart and the AMA Cub Pennyplane. streak balsa guillows powered sky glider rubberband plane kit wood air Their AeroLab CD includes an instructional video on building the Sky Streak. Go together in minutes but provide many hours of back yard entertainment. Recent kits come with a very heavy hook. 
The bright surface should disappear from view at the same time on both wings as you rotate it. Tie another overhand knot, but this time make the loop in the opposite direction from the first one. In addition, I will demo a competitive version that has special features. 1) Shaved and balanced prop with pitch increase of 2 degrees (less mass, longer prop rotation/ duration using 1/8 rubber) Hold one tip of the prop straight below the nose with one hand and hold the stick right behind the wing with the other. I have got 400 turns on a lubricated motor, but some do not seem to be able to take more than about 300. Then the propeller will pull the airplane to the right. This would be good for a class, scout or family group. For soft wood, holding it under the faucet for a couple minutes will be sufficient. You are putting more turns and energy into the motor and getting shorter flights! It turns more slowly, lengthening the motor run. Let the wing dry completely. You are now ready to launch the plane. streak airplanes guillow sky jetfire powered balsa wood rubber band flying windup bundle toys copter Now I will show you how to wet form wing camber using a form. 
This will allow a consistent right circle. Mark the position of the high point of the camber near each end. When dry, the tips sprung back to 1.3, increasing the dihedral from 6 degrees to 12 degrees. You can see that there are opportunities for further experimenting with this airplane. Thanks for the well detailed process with the Guillows Skystreak. 
Dirt, grit or sand can cut into tightly wound rubber, causing a nick that will eventually break. A larger propelleracceleratesa larger volume of air by a lesser amount and is more efficient. What this means is that the Sky Streak should not be expected to fly as long as relatively lighter models. It made a complete flight and landed upright on its wheels. Each set includes five components; a wing, a propeller assembly with shaft and bearing, a 7 rubber band motor, a parts sheet and a fuselage stick with wire motor hook. Here is a video of a 40 second flight. Increase the number of turns by 50 on each flight. I love your number 6. 
On closer inspection I found that the reflexed end of the prop hook was hitting the plastic bearing box. When the wood is completely dry, unwrap the Ace bandage. Place the whole thing on blocks to dry. A bright light shining on the underside of the wing will help you judge the match. Its main advantage is that it goes together quickly, in less than two minutes compared with around an hour for those other planes, and it doesnt require sharp blades, pins or glue. It has a lower margin for stability and adjustments can be very sensitive. Putting the motor in a film can is a good way to do it. Apply glue to keep the hook from sliding out of the wood. The name of the airplane, the length and width of the motor and the estimated breaking turns are good information to have on the label. After that, everything slips together according to the instructions. We want to make simple flying models easier, better and more accessible to the world! If the plane does not climb at all, move the wing forward closer to the propeller. Put the blocks and the jar exactly the same distance from each end. The weights of the components for one Sky Streak kit are: To calculate wing loading we need the wing area. First flight spun in to the right. Take it out every few minutes and try gently bending it to see how it is coming. The stock wing has 6.4 degrees of dihedral angle under each wing. After flying with the 1/8 motor I found that it was thicker than necessary. 
Start with the wing back at the 1/2 mark on the fuselage slot. It will wear out and break much sooner. You want just enough to overcome the left dive. With those modifications and 1,100 to 1,200 turns on the motor (79 to 86% of breaking) I have had many flights of 35 to 37 seconds. The tips were raised 1 11/16 (1 1/2 + 3/16), putting them 11/16 above the center. Slip an O-ring over the end and slide it down out of the way. The center was supported on a 3/4 x 1 1/2 x 3 block of wood to keep the inside ends of the forms off the table top. Start with the AMA Cub Master Class. I did that after the wing had completely dried out. 
Wood is stronger in the direction of the grain, so it is preferred to have the grain run vertical. Pull the strands apart to move the knot to about 1/8 from the ends. Check yours before putting it on the plane. Lube makes itnoticeablyeasier to put in more turns and the motor will last much longer. We will be modifying the wings to a quasi-polyhedral (tip dihedral) and upgrading to Tan II Sport for outdoor flying. Make a right angle bend (backwards or forwards) 1/8 above the stick. The motor and propeller will take it from there. balsa guillows When you are ready to move beyond the Guillows gliders, there are many good resources on the Internet. One difficulty is that the slots in the top of the fuselage for the pilot and the fin are not wide enough for these parts. I advise dampening the last 1/2 of the wing if you try that. balsa propeller This with the motor wound up only 80% and not the optimum motor. Not only will the cambered airfoil have a higher lift coefficient slope, the trailing edge will slant up, increasing the attack angle of the wing, also increasing the lift. toys flying airplanes streak balsa jetfire rubber sky band wood copter windup bundle powered play sports outdoor That is why it is important to have pencil markings on the wings and fuselage slot. 2 of the Sky Streak Motorplane in one box. Scrub it clean with steel wool. Here are two planes with the different size props. Insert the fin into its slot. Redampen and rework as needed until they match as closely as you can get them. About the only construction work required is to punch the tailplane, fin and pilot figure out of the parts sheet. airplanes streak jetfire powered balsa wood rubber band windup guillow bundle sky toys copter flying I would prefer more depth to the curve, but thats about all that can be had with this stiff piece of wood. Copyright 2019 The Balsa Cabin. After you have seen it fly a few times, you will have a better idea how fast to release it. The good news is it will be added to their camp next year. Pull the second knot up tight against the first knot. Weight it with clothespins to keep it from floating up. Experienced rubber power modelers know that it is not good to wind up a rubber motor without lubricating it. Start making the new hook by bending a full circle right handed helix with a tiny bit of straight overlapping at the end. Motors must be protected from light. I trimmed a Strato Streak using this excellent tutorial, learning a lot. Dont get water on the central 2 of the wing. Rebend it according to the following directions. Great educational video of beginner Rubber Powered FF Airplane from beginning assembly to end of flight. I remember buying the Strato Streak for $0.25 back in the day. It will keep its shape once it dries out. Place the wing against the board, with the leading edge of the wing along the leading edge of the form, closest to the greatest curvature, and the tip of the wing at the tip of the form. Shyam The original reason for making a new motor was to use a better quality rubber. A piece of paper can be folded on one edge to make a right angle. Once having seen this done with all the measurements and marking, you can see that there is an easier way to do it. Cut the wire 3/8 away from the bend. The problem with this is that the right roll will remain after the motor torque goes down. Take a close look from the front and top. This adds a little weight up front. The Sky Streak is available from Guillows in three forms of packaging; apoly baggedsingle, a double boxed set or in their Air Plane Design Studio, which contains parts to make four Sky Streaks, including landing gear that is not included in the other two sets. Tilt the wing until you can look straight across both edges. You can get many more turns into the motor before you see the left rolling dive. The plane is now complete and ready for test flights. If you have an older kit with thin wire, you may reuse the wire. Put stooge and winder in the search window. It is hard to make precise bends in steel wire while bending over a camera tripod and working at a distance. I found that bubble soap makes an excellent knot lube. Center the wing between the pencil marks. My first cambered wing was made with forms. The AMA breaks the wings and bends the tips up to increase the tip dihedral. Note just beyond my fingertips is one of the two form boards. Here is a video using a 15 loop of 3/32 rubber for the motor. ROG flights wont work in wind. You can also use the fin to reduce the left turn or produce a right turn. You will notice a change at first, but after a while you will not notice any further change. Also check that the wing is not twisted. Put 5 of water in a jar and soak one end of the wing in the water. Every few minutes check the wood for flexibility. You could see in the last picture that I lost a little of the dihedral. gliders guillows skystreak balsa propeller We want the motor to be free to unwind without rubbing on the stick, so we must make a hook that holds the motor farther from the stick. I found that bending wings around a 2 diameter jar would break the balsa. It slips together in less than two minutes without glue, pins or sharp tools. The circle can be about the same diameter as the hook on the propeller shaft. It can be used to teach principles of aeronautics and basic piloting skills. You can see that the kids are having a blast. This toy airplane has a one piece wing with a built-in dihedral. Do the same with the other wing and form. Many modelers prefer more stability and would use more. Coat the wire with glue and set it aside to dry. Tape the end of the Ace bandage to the back of the form, extending off the trailing edge. I found that bending wings around a 2 diameter jar would break the balsa. 
The Academy of Model Aeronautics is using the Sky Streak to introduce beginners to model aviation. Put one end of the wing into the water. I have two profile scale airplanes, an F4U and Japanese Jill using the bto fly that use the basic Skystreak with added material to assume the scale outlines. I did your recommended tune up and the results are transformational. Write the label. balsa guillow Lube relieves the internal stresses in the motor, allowing many more turns without excess torque. Look at the plane from the front and from below. Best Regards, I am teaching Robotics and AeroModeling was looking upon some information on how to improve the flight performance. Dave teaches kids how to build and fly Sky Streaks. I say slightly because the Sky Streak is a fairly heavy airplane that must fly fast to stay up. The jar must be exactly perpendicular to the wing span, unless you want a little built in roll. The wood has the grain running horizontally. 
The heavier prop will require the wing to be moved forward. Put the wood grain vertical for strength. Longer motors become harder to manage. The Sky Streak is a fairly heavy airplane for its size. You can try a few hand launches with the wheels on until you are satisfied that everything works. CM9 4XL. A right-right flight pattern can be accomplished with a bit of right thrust for right turn in the climb and a bit of right rudder to maintain right turn in the glide. You may have to lick your fingers to get them to stick to the parts enough to move them back and forth over the sandpaper. I made a 14 loop (HTP = 8) but I couldnt really get more than 400 turns without over-torquing the plane and sending it into a kamikaze dive. I considered that to be enough. The prop shaft is made from 0.045 diameter steel wire. You will need to scavenge a D6 propeller assembly or remove your D5 propeller from its hanger and replace it with a D6. The wing has a note on it WARP THIS EDGE DOWN IF PLANE DIVES LEFT. You wont be able to get much curve near the center. The AMA sells Sky Streak kits with the instruction sheet included, as well as a motor of 1/8 contest rubber. Unit 15, Heybridge House Industrial Estate, 
Hold the stick near the front end and wind the prop clockwise with a finger. Put the rubber band motor over the prop hook and the motor hook. 
Now that we have got successful flights out of our Sky Streak, we want to find ways to get longer flights. I recommend that you mark the wing and tail center before assembly. This helps insure that the wing is not twisted. If a motor gets in dirt, wash and relube it before the next flight. Extend themark to the edge of the wingtip. Guillow toy airplanes have been around for over 60 years providing millions of youngsters fun and enjoyment letting their imagination soar. Here is a video using 300 turns in the blue rubber band. BTW, a friend who teaches Lego Robotics is now interested in what youve done here so your mission of teaching kids about aeronautics continues. You have taken so much time and so many pictures illustrating every step. Check that everything is in the correct place before each flight. After each flight, some things may need to be put back in place. Then I ran hot water from the faucet over only the center 2 of the wing, blotted it dry, put the wing up on blocks and put a jar full of water (in a class, use a plastic jar full of sand) on the center of the wing. One way to measure the wing area is to trace the wing onto a thin sheet material of known, uniform density, cut out the pattern and weigh it. Otherwise the fin is much more susceptible to breakage. As you put in more turns, the torque of the motor increases. Let it dry out completely before moving it. Remember that side thrust is most effective at high torque, but not at all when the motor has unwound and rudder is most effective at high speed, but retains effectiveness at gliding speed. They have produced an instructional sheet for the Sky Streak, showing how they bend the wing tips up to improve lateral stability. The propeller and nose bearing made of hi-impact plastic. You will want two of them.). There were scratches on the box. That is the best way to do it. A good place to start would be the AMA Cub series on EndlessLift. gui balsa packs twin total toy wood guillow planes streak sky Later I will show you how to make modifications that will greatly improve flights. But a motor that is wound close to breaking will not last very long. Then I glued strips of 1/32 balsa sheet to the top surface, to increase lift the way the squirrel wing does, because I was too impatient to soak the wings and bend them. The added length brought no benefit so I decreased the loop size to 10 to save weight. Now start pushing the far end of the wire with the hook in it through the wood. Do not try to push the entire wing through the slot. You can read about those elsewhere on this site. 
It is helpful to have marks along the slot so you can keep track of where the wing is. When flying on a small field, consistent circle direction is preferred, whether left-left or right-right. They can be found online. The wing forms were cut to 6 lengths. Identify the leading edge. These all have paper covering on balsa frames, rather than sheet balsa surfaces. Place the wire in the glue and position it carefully. There may be situations where you will deliberately want something off center, but you still need to know where the center is. Other liquid soaps may be used, such as Johnsons Baby Shampoo. 
I bought the 3/16th Tan Super Sport Rubber to substitute for the same size blue OEM rubber motor. 
balsa plane wood streak guillow sky The Guillows Sky Streak is a simple, sheet balsa, rubber powered, free flight, stick, toy airplane. Cut 1/4 pieces by rolling the wire under the razor blade. A hard throw will result in a zooming, nose up stall and a fall. 
It takes less rudder or sidethrust to correct the torque roll. I found that it could be used if it was refreshed before every flight. Apply a drop with a toothpick. Denny Dart II 0.185grams per square inch. We are going to make a motor that is twice the distance between the hooks, which is about 7. The wing loading is thus 11.61/22.99 = 0.505 grams per square inch. Here is what it looks like when we are done. This article takes me way forward in my thinking Thankyou! The stiffness of the balsa will force the curve to be gradual. I have worked up to as many as 400 turns. My ultimate Sky Streak originally had a 6 prop, a 14 loop of 1/8 rubber, cambered wings, an improved motor hook and a bendable rudder. Dave Gee, who is on the AMA Education Committee, has produced a YouTube video showing him assembling a Sky Streak according to the AMA instructions. Place a block of wood on the main portion of the fin to keep it flat on the table. Notice that there is more curvature near the leading edge. ), When you are satisfied with the shape of this wing, put the other end in the water and shape that wing. Grab the tag ends tightly with a clothespin and pull hard. Such a great source of information you have given us. You cant rebend a removed shaft, the wire will likely break. You will find that different combinations of side thrust and rudder can accomplish similar or different flight patterns. This can be very annoying when you have a tightly wound, lubed motor in one hand and a prop in the other.

Think of them as fuel that you burn. These marks show where the edges of the 3/16 wide stick should go when the wing is inserted through the slot in the stick. Near the trailing edge, it is almost straight. Continue counting in the same way, One, two, three, four, five, six, seven, eight, nine, TWO, one, two, three, four, five, six, seven, eight, nine, THREE, one, two, three, four, five, six, seven, eight, nine, FOUR, , one, two, three, four, five, six, seven, eight, nine,FIFTEEN. That is fifteen tens, or 150 turns. With the left wingtip down, the plane slips downward to the left. We can also make a rudder with flexible wire hinges. I found that it worked without the glycerin, but like all liquid soaps, it dried out quickly. Mixing in a little glycerin would help. I decided to try bubble soap because it is likely available in many of the places where you would find Guillows toy planes. We want to leave the center 2 of the wing alone for now. I will camber the wings and put in dihedral, as well as add the other modifications before the event. I am continually impressed with Garys devotion to kids and flight and have begun looking again for an indoor venue. First put marks along one edge of the wing 5 in from each tip. You can also slide the wing a bit to the left. Now bend the straight piece out from the circle around a small radius. Contest quality rubber is not as tough as the kit motors, but it can take more turns and store more energy. If you are teaching a class, use a plastic jar full of sand or gravel. See them at the Guillows site here: If you buy them from Guillows online, consider getting a bag of extra motors and 6 props as well.

The circle can be about the same diameter as the hook on the propeller shaft. It can be used to teach principles of aeronautics and basic piloting skills. You can see that the kids are having a blast. This toy airplane has a one piece wing with a built-in dihedral. Do the same with the other wing and form. Many modelers prefer more stability and would use more. Coat the wire with glue and set it aside to dry. Tape the end of the Ace bandage to the back of the form, extending off the trailing edge. I found that bending wings around a 2 diameter jar would break the balsa. 
The Academy of Model Aeronautics is using the Sky Streak to introduce beginners to model aviation. Put one end of the wing into the water. I have two profile scale airplanes, an F4U and Japanese Jill using the bto fly that use the basic Skystreak with added material to assume the scale outlines. I did your recommended tune up and the results are transformational. Write the label. balsa guillow Lube relieves the internal stresses in the motor, allowing many more turns without excess torque. Look at the plane from the front and from below. Best Regards, I am teaching Robotics and AeroModeling was looking upon some information on how to improve the flight performance. Dave teaches kids how to build and fly Sky Streaks. I say slightly because the Sky Streak is a fairly heavy airplane that must fly fast to stay up. The jar must be exactly perpendicular to the wing span, unless you want a little built in roll. The wood has the grain running horizontally. The heavier prop will require the wing to be moved forward. Put the wood grain vertical for strength. Longer motors become harder to manage. The Sky Streak is a fairly heavy airplane for its size. You can try a few hand launches with the wheels on until you are satisfied that everything works. CM9 4XL. A right-right flight pattern can be accomplished with a bit of right thrust for right turn in the climb and a bit of right rudder to maintain right turn in the glide. You may have to lick your fingers to get them to stick to the parts enough to move them back and forth over the sandpaper. I made a 14 loop (HTP = 8) but I couldnt really get more than 400 turns without over-torquing the plane and sending it into a kamikaze dive. I considered that to be enough. The prop shaft is made from 0.045 diameter steel wire. You will need to scavenge a D6 propeller assembly or remove your D5 propeller from its hanger and replace it with a D6. The wing has a note on it WARP THIS EDGE DOWN IF PLANE DIVES LEFT. You wont be able to get much curve near the center. The AMA sells Sky Streak kits with the instruction sheet included, as well as a motor of 1/8 contest rubber. Unit 15, Heybridge House Industrial Estate, Hold the stick near the front end and wind the prop clockwise with a finger. Put the rubber band motor over the prop hook and the motor hook. Now that we have got successful flights out of our Sky Streak, we want to find ways to get longer flights. I recommend that you mark the wing and tail center before assembly. This helps insure that the wing is not twisted. If a motor gets in dirt, wash and relube it before the next flight. Extend themark to the edge of the wingtip. Guillow toy airplanes have been around for over 60 years providing millions of youngsters fun and enjoyment letting their imagination soar. Here is a video using 300 turns in the blue rubber band. BTW, a friend who teaches Lego Robotics is now interested in what youve done here so your mission of teaching kids about aeronautics continues. You have taken so much time and so many pictures illustrating every step. Check that everything is in the correct place before each flight. After each flight, some things may need to be put back in place. Then I ran hot water from the faucet over only the center 2 of the wing, blotted it dry, put the wing up on blocks and put a jar full of water (in a class, use a plastic jar full of sand) on the center of the wing. One way to measure the wing area is to trace the wing onto a thin sheet material of known, uniform density, cut out the pattern and weigh it. Otherwise the fin is much more susceptible to breakage. As you put in more turns, the torque of the motor increases. Let it dry out completely before moving it. Remember that side thrust is most effective at high torque, but not at all when the motor has unwound and rudder is most effective at high speed, but retains effectiveness at gliding speed. They have produced an instructional sheet for the Sky Streak, showing how they bend the wing tips up to improve lateral stability. The propeller and nose bearing made of hi-impact plastic. You will want two of them.). There were scratches on the box. That is the best way to do it. A good place to start would be the AMA Cub series on EndlessLift. gui balsa packs twin total toy wood guillow planes streak sky Later I will show you how to make modifications that will greatly improve flights. But a motor that is wound close to breaking will not last very long. Then I glued strips of 1/32 balsa sheet to the top surface, to increase lift the way the squirrel wing does, because I was too impatient to soak the wings and bend them. The added length brought no benefit so I decreased the loop size to 10 to save weight. Now start pushing the far end of the wire with the hook in it through the wood. Do not try to push the entire wing through the slot. You can read about those elsewhere on this site. 
It is helpful to have marks along the slot so you can keep track of where the wing is. When flying on a small field, consistent circle direction is preferred, whether left-left or right-right. They can be found online. The wing forms were cut to 6 lengths. Identify the leading edge. These all have paper covering on balsa frames, rather than sheet balsa surfaces. Place the wire in the glue and position it carefully. There may be situations where you will deliberately want something off center, but you still need to know where the center is. Other liquid soaps may be used, such as Johnsons Baby Shampoo. I bought the 3/16th Tan Super Sport Rubber to substitute for the same size blue OEM rubber motor. balsa plane wood streak guillow sky The Guillows Sky Streak is a simple, sheet balsa, rubber powered, free flight, stick, toy airplane. Cut 1/4 pieces by rolling the wire under the razor blade. A hard throw will result in a zooming, nose up stall and a fall. It takes less rudder or sidethrust to correct the torque roll. I found that it could be used if it was refreshed before every flight. Apply a drop with a toothpick. Denny Dart II 0.185grams per square inch. We are going to make a motor that is twice the distance between the hooks, which is about 7. The wing loading is thus 11.61/22.99 = 0.505 grams per square inch. Here is what it looks like when we are done. This article takes me way forward in my thinking Thankyou! The stiffness of the balsa will force the curve to be gradual. I have worked up to as many as 400 turns. My ultimate Sky Streak originally had a 6 prop, a 14 loop of 1/8 rubber, cambered wings, an improved motor hook and a bendable rudder. Dave Gee, who is on the AMA Education Committee, has produced a YouTube video showing him assembling a Sky Streak according to the AMA instructions. Place a block of wood on the main portion of the fin to keep it flat on the table. Notice that there is more curvature near the leading edge. ), When you are satisfied with the shape of this wing, put the other end in the water and shape that wing. Grab the tag ends tightly with a clothespin and pull hard. Such a great source of information you have given us. You cant rebend a removed shaft, the wire will likely break. You will find that different combinations of side thrust and rudder can accomplish similar or different flight patterns. This can be very annoying when you have a tightly wound, lubed motor in one hand and a prop in the other.
