Help Needed! Electric ultralight motor mount
This year I purchased an ultralight flexwing trike with a Geiger electric propulsion system. The owner had flown the aircraft a few times but I was skeptical of the motor and controller mount that they had designed and were flying with. It was a mismatch of different hardware, bike bolts, and a lot of JB weld (see below).
I tried to redesign with 30x30mm 6082-T6 and AN hardware (pdf attached), although the design ends up heavier than the original and I fear I have overengineered a solution which is ultimately for a 12lb motor and 3.9lb controller. I have considered a welded frame or even a composite one but I feel it may be a bit beyond my expertise.
Any thoughts or suggestions would be greatly appreciated!
