Oxy 2 Main Gear

thingiverse

3D printed main gear and belt pulley for Oxy 2 helicopter. Belt pulley has 5 more teeth than stock to increase tail drive ratio. You may need to shorten the tail boom slightly to get the belt over the new pulley. NOTE: STL with stock pulley ratio has been uploaded. Print from PLA, use supports on build plate for gear, none required on upper belt retainer. This has been flight tested, and after half a dozen flights still looks new.
