Help Me Choose a 12s Motor for 20+lbs savage

[Jahay]

he said
But you can use rough sandpaper and motor connected to ESC and than run the motor on that sandpaper.... Could work.. .so if i do decide on the leopard, ill give that a go...

But i think i will run my 1520 for now. It was doing so well before, i will just gear the pinion a little smaller (bit worried about running a 9-10t) and up the voltage to 9s and see if it can handle it... If not, then ill just get a new one...

What is the worst that can happen if a motor blows? will the esc and batts blow too?
