Mechanical Brakes

the speed calc. says around 40 mph on 4s which is what i run my 9xl on, i will just run it till i thermal or ruin the motor

thanks for the suggestions, do you think that i should consider a 1700kv motor and keep the gearing the same? would the temps be ok?

so a 1515 2.5d /s would be a good option? the speed calc. says it would be 39mph


i think it felt much better with this braking and i was only running on asphalt
