Tron 5.5 Gemini/Orion Motor Pinion 17T 5MM

Tron makes great helicopters and their innovative design for these motor pinions and motor mount system works excellent. These pinions are strong, durable, and work exceptionally well. I set up my Gemini helicopter a little different than I have with my other helis in the past. I went for a lower kv motor and a higher tooth count count on the pinion to see what kind of performance, efficiency, and flight time I could get. The Xnova motor I purchased had a 5mm shift and I needed this 17T pinion to put on it and get the head speed at the desired throttle percentage I wanted.
