THe RCM mount gives you more gearing options than the Losi if I recall correctly. Might want to do some seatching in the older threads for that since it will be a concern with the HV setups. My RCM mount was abe to do 12/50 gearing without issue and without shimming the diff up off the chassis at all though. Can't wait to see them up and running though, I've been eying the XL for some HV projects myself.
