Banggood

had to make changes to the motor housing for it make a good connection to the reduction gear

Nice quality. Strong and fit perfect.

I just received it, i haven't install them yet. Seems ok

seems good is a tight fit on the drive shaft, has 2 extra teeth then my stock plastic so bad to order the adjustable motor mount because if the tight fit

so my plastic spur gear started to ware out and i decided to get this and it works really well but the only problem with it is that it is quite hard to get it on the center driveshaft

Muy buena calidad, resistente, calidad precio excelente, el envío tardo un poco en llegar pero bien

For when my plastic runs down will replace with these.

Its a great upgrade for the stock gear in a959b, a979b. Needed for sure if you go brushless
