After some calculation ... i found that if i want to use the 3s 2200mah 35c lipo , i can only use the 60a esc for my truck . Anyway , i also heard pple say that the bullet can only sustain a 60a esc . Anything more , you have to start stocking on spare parts already . So any good 60a esc to recomend and also do i have to change the motor ?
