dont need more speed mine flys along,keep up with just about everything
but......
it really surprises me the speed it does and not blown up and how long ive had it and only changed the wheel bearings, for a rtr model that cost 150 quid i couldnt want more
ive changed it a bit now,slightly smaller dia tyres rally pattern and put a 1/8 ford mexico shell on it
even lowering the gearing with the tyres its still a blast to run
well happy
