If You have bought the Stearman PT17 fra 3d labprint:
With this hack, you dont need to reverse the shaft!
(This includes only a hack - not the starmotor!
- You might have realized that You have to reverse the shaft of the motor, which I didnt succede in doing cause one of the screws holding the shaft is stuck.
If You want to reverse the shaft, take a look here: https://www.youtube.com/watch?v=4jSix3rUI2E
The motor is: Turnigy 3542/5 1000-1250KV
I have added an stl model with the support 1 mm thicker for those of you with a smaller motor. It seems thou that the Turnigy Aerodrive SK3 only has 3 holes in the back for fastening, and my has 4 - if that is correct I have to make a more timeconsuming alteration of the original!
The 4 bolds are DIN917 M3 x 16mm. You have to expand the hole in the front of the starmotor one mm or so, with a roundfile!
