Just received this motor. It's very well made. It's actually Suxfly motor but the pic above does not show that. The shaft is 3mm as stated. Length is 45.17mm and diameter is 24.05mm exactly.

Very pleased with purchase!

I`ve put this motor in a Holliday buggy white a 20t pinion and the 60amp esc toke some hobbying to fit it in this car because normally a 20t does not fit. I’ve put a peace of (children’s) straw on the shaft to get it to 3,17mm, that worked fine. Used the Turnegy 5.000 mah lipo. power, almost uncontrollable. The 350 watt of power makes the car wheelie when you go from half throttle to full power. Great great great for just a little money

Engine excellent quality! They come in pretty boxes, perfectly packaged. I bought two of these engines as a test for the F-14 EDF. The parameters seem to be good. After testing I will describe the relationship.
