You'd rather use aerodynamic surfaces for turning as well as the speed increased. It would start resembling aerobatic aircraft like Extra 300. High aerodynamic acceleration is an old thing, it's how they actually discovered G-induced loss of consciousness. If you are mostly doing the racing with electronic motors, there's less noise and it's not as interesting anymore. Therefore some airstream operated whistle or siren would be useful, as you could deduce the speed directly from it: http://www.youtube.com/watch?v=nC9Lmr5mjJQ http://www.youtube.com/watch?v=nC9Lmr5mjJQ
