X-UAV Mini Talon Twin Motor Conversion

thingiverse

!UPDATE! - 12 March, 2017 I've made some significant updates to the files with a few key changes: Removed the 1.5 degree downthrust as testing proved it wasn't necessary. Optimized and smoothed out the shell for better performance. Moved the key back to sit behind the spar clamp for added security. For more information on this project, check out my build page here: http://www.itsqv.com/QVM/index.php?title=X-UAV_Mini_Talon_Build_Number_3 My test plane is flying beautifully, but it's a bit sensitive during launch. I've found that the best throws are straight and level with no pitch up or down and at 100% throttle. This project was done by request and has turned out pretty well so far. Originally, I considered a smaller diameter version like the Bix3 piece on Thingiverse - http://www.thingiverse.com/thing:469613 However, the problem with those modules is that there's no way to remove the motor without un-glueing the motor pods. The larger diameter solves this issue and creates enough space inside the pod for easy connect/disconnect of extra motor wire. I did consider adding enough space for a small ESC, but it could present issues with too long battery wires as well as heat build-up, so I've parked that idea for now. Key points: This motor pod/nacelle is designed for a 22XX stator size motor like the Cobra 2213 or Turnigy SK3 2830. The cross mount holes are 3.1mm and on a 33.5mm bolt circle. The weight prediction at 25% infill is 27g for PLA, but when printed at 35% in ABS, it came out to ~23g. There's now zero downthrust. The nacelle fits just outside the M3 wing clamp hole, giving clearance for up to an 8" prop. Because of a slight wing taper at this location, there are Left and Right nacelles. There's a "key" that slots into the rear of the nacelle as added security/strength against bad glue or vibration failure of the joint. Enjoy building this!
