Description

I designed this part to convert the traditional tail rotor setup to a direct-drive tail motor. With a direct drive tail motor the part count is reduced substantially. I hope this will improve reliability and reduce maintenance. 

Dimensions: 

  • 19mm bolt pattern diagonally

Hardware:

  • 1x M3 insert
  • 4x M3 bolts for motor mount
  • 3x M3 bolts for attachment of bracket 

Support my work: All of my models are available for free. If you'd like to show your appreciation, consider Buying Me A Coffee.

Filament: PLA or PETG

My setup: I’m planning to run it with ArduPilot. The tail motor is a Hobbywing 3110 900KV paired with a 10" triblade prop and a separate 70A ESC. None of this has been tested yet, so I’m not sure if it’s the perfect setup
