It's easy to go brushless but with more power comes the chance of breaking driveshafts and shredding the plastic teeth on the gears inside the gearbox.Great idea, thanks. Tried that on my both of the trucks. Not much difference on the weak truck, maybe a little faster on the stronger truck. Maybe I’ll just get a couple new motors. Is it easy to go brushless or does that involve other modifications? The trucks are for my boys and of course one can’t be faster than the other.
