I've already got a 6.5 Novak that came with my GTB, I've got a 5.5 coming. I think a 4.5 would be too fast for offroad, great down the straights but too much elsewhere. I think its the equivalent of a 6-7 turn brushed!
I'm tempted to put the brushless in the 2wd for Teesdale as its got to come out of the Pred for the National the week after anyway
