    Hi
    Do you think that I can change the original motor of my 1/16 Brushless 4WD Racing Buggy w/25A System, to this motor?

    Thank you for you help.

    very strong! but don't use to long screws to mount it on the motor plate. I pushed the front plate out of the motor... was fixable, but not nice.

    Nice motor. But be sure to re-glue the caps. Mine came loose.

    Excelente motor para usar en el Easy Glider: con pilas de 2 elementos (2200mah). OJO: con baterias de 3 elementos se puede quemar gacilmente (ver Bungymania)

    I bought it for the Multiplex EasyGlider, using the standard gearbox that is coming with the plane.

    It worked very well and increased the power substantially over the original brushed motor.

    It is powerful, lightweight and cheap, what else can you need?.

    I recommend it.

    Needs 2s NOT 3!

    Apr 06, 2009

    This motor gets too hot too fast with 3S 11.1 v but runs normally with 2S at same capacity.



    Stuck this into a firebird freedom. It works ok but I still think it gets hotter than it should.

    Id give it 3 stars not 5
