Strawberry Strudel

Maiden flight - went perfectly

Second flight - crashed it at the end, but it amazingly suffered no damage.

Introduction

I wanted another wing exactly the same as the orange sherbert, but with the possibility of adding a small aio fpv camera.

Components (~25 camera not included)

  • Mars Power 1806 2280kv with 2 blade 5040 props
  • Turnigy 10a plush esc
  • 2x 3.7g servos & push rods
  • 4 gram micro receiver
  • various bamboo skewers for spars
  • 1 sheet Dollar tree foam board + red tape
  • foam pipe insulation (fpv & battery holder)

Conclusion

My initial worry in building this was how the foam pipe insulation would affect the aerodynamics of the plane. Overall, I built this to be much stronger than the orange sherbert (and heavier at 166grams). After flying the sherbert for a few days and crashing it dozens of times, I've learned all the weak points that need reinforcing and made the necessary changes into this new design. It came out a bit heavier, but should be several times stronger.

The maiden flight went perfectly and I crashed it accidentally on the 2nd flight. It didn't crash nose first 90 degrees hard, but it did take a good tumble as you can see in the second video. Amazingly though, there was not a scratch on it. Looks like the structural reinforcements are working as designed.

Although the foam pipe insulation did affect the overall feel of the wing, I can't say that it is as bad as I feared. The wing still flies very well and is still quite aerobatic and fast. This is looking to be a winner.

Update: 12/31/17

The wing did amazingly on the cross country trip that I took it on. My only complaint was the 3.7g servos that started fading on me at the end of the trip. I pushed it a bit too hard towards the end and was unable to recover from a dive that ended up in a crash which killed a bearing on the motor. The other weak point was the foam pipe insulation coming apart after the numerous crashes. The frame was still in near perfect condition, amazingly! I can't realistically expect any wing surface fpv mount to survive the number of crashes it's been through though. I'll be taking the lessons from this for my next wing for sure.
