28mm Motor Mount and Nosecone for GWS Formosa/HK "Patternish Ship"

thingiverse

This is a nosecone and motor mount for installing a standard 28mm OD motor on a GWS Formosa or the Hobbyking clone called F3A "Patternish Ship". The terrible name aside, it was designed to be printed with the front section against the print bed. I printed it in ABS, though PLA should work fine too if you don't crash and burn. The final weight (not including the motor) came out around 68g, but thinning the walls or decreasing the fill would lower that further still. I'm using a 28-26 motor in the 250w range, and the cowl flows more than enough air to keep it nice and cool. A longer motor would also work just as well. Two motor mount holes are spaced 16mm apart, while the other two are spaced 19mm apart. You may need to rotate the mounting hole pattern so the motor wires line up with the channel designed into the side of the motor bay, but any of Hobbyking's NTM Propdrive motors should line up correctly without a hitch.
