I want lots of bottom end for clearing jumps but I want top end for long straight aways.
A friend keeps telling me to get the SH PT-2016 xbg, but I know nothing about the SH motors and I remember how great that Novarossi engine ran and I'm reluctant to buy something I don't know anything about even though it's cheaper.

Thanks
