RC motor mount generator with thrust angle
RC planes usually need 2–3° of down- and side-thrust. Instead of washers, this mount builds the angle into a wedge so the motor face is exactly where you want it, with the motor's X-pattern and four airframe screw holes.

How to make it
- Choose motor pattern.
- Set down-thrust and side-thrust angles.
- Print solid in PETG/ASA/PA-CF.
Print tips
- Motors get hot — avoid PLA.
- 100% infill around the screw pattern.
FAQ
Which way is side-thrust?
Positive side-thrust points the motor to the right (seen from behind) to counter prop torque on a tractor setup.
