lets just say if i were getting either a buggy or tuggy could a 10xl on 4s work for mild racing, could it be geared enough to be competitve mainly against nitro, i ask because i have one and i have a hacker maxx motor with no rotor but that motor gets pretty hot

running a bk 9920 what is a decent external lipo cut off i can use
