I m planning 10.5 with a tad of boost so start with in my xx my worry is not gearbox as I remember running silly winds in the old brushed days but wishbones specifically fronts .I haven't seen any for sale for a while (I have xxx to and suffering same issue)
my boy just launched his fabiix cougar MM up the road yesterday as a trial with a decent 13.5 and a fair helping of boost and it went like a scalded cat !!
if its indoors and for "gentlemanly " races 10.5 should be safe and ample
