#160773 - Firebolt 12T 550 Motor

The Firebolt 12T, 550-size motor is the standard Motor in the Monster King RTR! The extra-large size means you'll get extra torque for excellent acceleration and "pop" over jumps.

Features standard motor mounting screw locations for an easy drop-in fit for most 1/10th scale RC kits.

Hiya I have a brushed hpi blitz that I believe is the 15 turn motor but that hs just died and I was wondering would this work as a little upgrade or best to stat with a 15t ??

Phil Goleby / 3rd May 2026

It depends on your ESC (speed controller). If it can handle down to 12T then yes, this would be a nice little upgrade from your 15T. If not (or you're not sure...) might be best to stick with 15T.
