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

Last crawled date: 3 years, 1 month ago

This is a nosecone and motor mount for installing a standard 28mm OD motor on a GWS Formosa or the Hobbyking clone, which is called the F3A "Patternish Ship" (terrible name, I know). It was designed to be printed with the "front" section against the print bed. I printed it in ABS, although PLA should be fine too if you don't crash. The final weight (not including the motor) was around 68g, but thinning the walls or decreasing the fill would lower that further.
I am 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. Two motor mount holes 16mm apart, and the other two are 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.
