Close but no cigar! Thats the combo that gave me the idea, but unfortunately the 1mm prop shaft seems to be a bit of a let down. I occasionally turn my micros into lawn darts so I needed a better gearbox solution.

The new mCPX BL tail motor in the UM gearbox
This new BL motor has a diameter of 8mm so with a layer of tape wrapped around it it should slide directly into the UM gearbox. Then the mCPX 9t pinion should fit the motor too so I dont need to mess around with pinion pullers
I believe the mCPX BL tail motor is 8000 and something KV, and coupled with a 6a 1s ESC it should be a winning combo. I think a 3a 1s ESC should cut the mustard though, but better to be safe than sorry. 1220 11000kv Inrunners pull around 4-6a so the 8mm 8000kv should pull less amps in theory.
