Mini Flying Wing: MiniWing v2

Miniquads are fun, right? After all, there is a reasons most uf us flies 210-250 quadcopters. If so, small flying wings should be fun too! I tried that already in late 2015 and failed miserably! My design did not survived maiden flight. Well, things like that happens from time to time, so few months ago, after learning few new things, I’ve made a second attempt. And this time I’ve succeeded.

Parts

  • 2x 9g servos from Banggood
  • Multistar 2206 2150KV motor
  • 12A ESC that burned from moisture and I replaced it with EMAX 30A ESC I had on hand
  • Tunigy nano-tech 1300mAh 3S 45C LiPo pack
  • Airbot F4 (MPU6500 version) FC running INAV
  • FrSky X4R receiver

Plans

I do not have detailed plans “per se” of this design. But, thanks to amazing website Flying Wing CG Calculator I do have wing dimensions:

  • 580mm wing span
  • 200mm root chord
  • 160mm tip chord
  • 150mm sweep
  • 100mm “fuselage” width
  • Center of Gravity (CG) at 20% of MAC, 95mm from the nose

Airfoil is KFm-3. Simple to build and with good flight characteristics. Wing is made from 3 layers of 6mm Depron board reinforced with 6mm carbon fiber spar that goes for the whole length of the wing.

Does it flies?

Well, yes it does. Maybe not that smooth as I wanted, but it flies well enough. It’s just very wind sensitive. After all it is pretty small, and after adding FPV gear slightly too heavy. Here are few videos:

Next iteration

Small flying wings are fun. Really. But they do not last long. After 4 months, my wing reached end of the line. It still flies, but needs replacement ASAP. This is why, work on slightly bigger (700mm wing span) wing has begun. New design will be given stronger power plant too: 4S instead of 3S and much more powerful miniquad motor.

  1. Hello! Great post! 😀
    I’ve been wondering how to use the servo outputs, in airbot f4. Can you help me out, please? 🙂
    I’m using the TRI mixer.
    Thanks in advance.
