Lets see how far the cars fly on the one I've got set up for now - taht is if/when I get the thin plywood! Its about 3x car height, with a nice swept kicker lip to it and then I've got enough to certainly make one 5-6x car height..). So things could get quite airbourne!!
All we have to do is try and find something suitable for longer landing ramps and see where we place them! I wqas thinking of some 'simple' basic triangle ramps for landing again with whats left of the thin plywood on them to help cushion the landing... Suck it and see a bit I reckon...
