just a reminder that ko propo vfs-1 pro comp = hara twister 2.1 inside. hara just has a carbon fibre looking exterior that's all.
I would recommend waiting for the pro comp 2. it will be the newest esc out when its out i think. also if you don't want a pro comp 2, the price for the pro comp will drop too. so its a win win situation!
if you want water proof the mx is the way to go, i have read the threads here for a bit (never used one myself since i have a vfs-1 pro comp)... and basically everyone's said it is 100% waterproof.
I do not know anyhting about the icube (haven't even seen many threads on here about it).
