Neil and Terry, not dissin what you've done at all, just that it would make the cars fly better (off throttle) if we did add some kick to them.. As they do in the worlds of mtb and bmx jumps. Simple straight ramp jumps don't make life easy for you and as Terry said, its then about throttle control all the way thru... sometimes its nice and easier to just let it 'fly'
