With those cool temps, It sounds like you can go up a few pinion teeth and still be in the safe zone temperature-wise. On top of that, your buggy will be flying!
Bahahaha of course the temps are cool, he ran it for 2mins before it broke, and he's wearing a jumper, must be cold outside. Good luck in the summer months, that motor will be smoking hot with the 18t pinion
There must be a lot of helicopters flying over where you bash your 'Losi'. In every one of your videos (that I've watched), I always hear a helicopter.
