AR Wing Motor Extension Mount
Description
Work in progress. As of March 2023, this is untested in flight. --- A wing extension / motor mount for the 900mm ARWing by SonicModell The main objective is to make the wing more efficient and less noisy in flight. The part moves the motor further from the abrupt trailing edge of the airfoil, and transitions it to a thinner profile, so the prop can chop cleaner air. It also moves the CG rearward, which would allow for a slightly heavier battery and still balance. It adds a small amount of wing area, which will help maintain wing loading with any additional battery weight. A version printed in with regular PLA was about 3 oz and felt heavy, even with only 3 walls and 15% infill. This one printed in light weight PLA (PLA-LW) seems to be strong enough (same settings) and is only 1.5 oz. Print with the leading edge down.
