6 / 7 Degree Motor Wedge for Zeta Wing Wing Z84

thingiverse

I put a very powerful motor on my Z84 (Cobra CP-2210 2200kv) and found the original thrust angle to be enough to make large throttle changes downright dangerous due to the nose pitching down so agressively. This wedge is an attempt to fix this. I remixed this to add the 6° of up angle on the motor and added cut-outs so that the motor wires would still route through the mount / let air still flow out the back of the model. The wedge is installed with the thinnest part straight up to bring the motor thrust line closer to zero. This part does not change any left to right thrust angle. Flight testing shows a HUGE improvement. I still get a pitch down moment at very high speed but this has improved the flying characteristics a LOT! https://www.youtube.com/watch?v=IIE6uRFDafc
