High speed G-maxx for ISC event, 100mph or bust

[_paralyzed_]

It seems to me the biggest problem at high speeds is the body acting like a parachute and the truck lifting, jze always ran no body. You can seal the edges of the body but the wheelwells will always be taking in huge amounts of air.

My thinking is that the body needs to be as "aerodynamically transparent" as possible. Basically a swiss cheese body. So the air doesn't get "caught' under the body. Once testing begins if you could sacrifice a body to try it could make a difference.

I really think they only lift at speed because of the body, they don't seem to lift bodyless.

Just thinking out loud.......

Actually I did run a body.....That is why it would act like a kite.

Your probably correct on the body causing lift after a certain speed. The theory of using no body to aleviate lift at those speeds would be spot on, but then you are faced with overcoming the drag. A front wing might be the key for getting the majority of the air to flow over the truck - I'd even consider one that extended beyond the wheels.

maybe drill a lot of holes in only the rear to let air out and try mto maybe cover up some of the wheel wells up to keep as much air from getting in?
