Hot motor !! So I'm burning up motors and its driving me nuts. It starts with an 8lb. rig with a rc4wd R2 tranny with 8t pinion. Disruptor transfer case to wraith axles with stock gears ? Motors are hot after 3 min. Right now There's a Novak timbuk2 brushless combo installed. Please help !! Already lost my Holmes torque master 27t yesterday. |
Re: Hot motor !! Something is binding, maybe. Remove pinion and roll by hand and see if everything is moving freely. Is gear lash good? |

Re: Hot motor !! A couple of things you can try are: lower pinion/spur gearing and a motor heat sink with fan. |
Re: Hot motor !! Hot motors are a few things that are related: Too fast a motor for the application (low wind count for brushed, hi KV for brushless) Too high a gearing (large pinion and/or small spur) Driveline binding (including the pinion/spur mesh) A low geared trans should actually help (low gearing = high motor speed, low axle speed). |
Re: Hot motor !! Rc4wd has a 1:1 gear ratio transmission for worm gear axles. Do you have that one or the geared down transmission? Because they look exactly the same. |
