k1 keeps overheating my motor
Hi this is my first proper 4wd buggie.
I got it yesterday secondhand with a hobbywing 120a speed controller and a 10.5t motor an it cut due t over heating.today I put in my speed passion controller an 7.5t motor and it just keep cutting out/overheating.Seems OK just going round half throttle but when you start to open it up etc it just overheats/speed controller cuts it off. I tried a thew different pinions an non made a difference. The belts feel tight but I don't if they are over tight |

Check the gearing against the motor manufacturer recommendations.

how tight?
maybe try loosening them off a bit? tight belts can cause overheating. |

hi jamesscott32
Try to remove the pinion, turn the spur and feel for it´s free or some is to tight, if its nice and free, then it might be your ESC/Motor thats the problem |

Also, if it isn't the belts it would be worth checking your drivetrain is nice and free and not having strain from say a bust bearing etc.

With the kit spur there's little choice of what pinions you can use. I run a 6.5 on a 22 pinion but if you're trying to run larger then it could be the mesh is too tight.
I was running mine and over jumped a jump landing hard causing the motor to move slightly causing the mesh to go slightly tight. After the run the car was stinking hot, nearly cooked the motor. I run the belts loose if if they're like banjo string then that will be a contributing factor. |

is your speedo running boost and turbo?
that will cause overheat and only effect on full throttle, right belts are right on any throttle position

I lost 4 motors this year in my K1. Tried everything, gearing ratio, mesh, belts, etc
Turned out the be the neutral, forward and brake sync position between the handset and esc werent set correctly, which meant it constantly had a high drag brake, which is bad news it seems Once these were set, it ran perfectly well
