you haven't specified if you're running the forward only conversion either

as for the bb in a savage
it is considerably heavier then the revo
i have a mgt 8.0 i use to introduce people into rc
it has great power and speed
but i don't think an 18 would be practical in the mgt
well at least i don't think the fun factor would be there that's for sure
