Tarmo4 SunnySky X2820 Motor Adaptor
thingiverse
Bought a SunnySky X2820 motor as the spec'd D3542 (DYS/Turnigy) motor wasn't available at the time. Unfortunately, the gearbox input shaft is too complex to remodel in TinkerCAD, so I just made an additonal coupler to link the motor to the standard input shaft. X2820 motors has 12.5mm hole spacing. Tip: Use some electrical tape to ensure the coupler sits snuggly in the stock Tarmo4 input shaft.
