Details

Choose from multiple turn options to dial in the right balance of speed and torque for your 1/10 off-road or crawler build.

A 550-size can helps deliver stronger low-end pull than many 540 motors, making it a solid upgrade for heavier rigs.


Dimensions and mounting details are laid out for easier fitment planning in common 1/10 RC motor plates.


Detachable construction simplifies cleaning and maintenance after dusty runs and muddy trail sessions.

Two silicone leads are included for quick wiring to your ESC.
