does this fit and work with stock esc on rally extreme? Thnaks
 meeki 780 points
No, max current would be too high for stock ESC, it also has a 3mm shaft so a different pinion would be required.

will this fit in the 1/10 Quanum Vandal 4WD Electric Racing Buggy (KIT)?
 meeki 780 points
No, you need a 3650 "540" size motor for that kit.

I want to replace a current motor I have with one of these, how do I find a gear that fits my current gearbox? the gear on my current motor is 6mm diameter with 8 teeth.

Does this motor suitable for this ID 9052000005 combo's regulator? I've burned my motor and want to replace it.
 Aprilia998 13 points
This motor is max 32A, the regulator in 9052000005 combo's is max 25A (burst), so you should buy also another ESC as well (or find another motor).

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.
