How to jump?

[sim]

I have limited experience driving a buggy indoors. Last Sunday, the local qualifiers for the Tamiya Asia Cup started again and this year, they had a big ramp that angled about 30+ degrees and was maybe 3 or 4 feet high.

My buggy was doing front flips (somersaults) quite often on that ramp and when I checked later, there was yellow paint left on the bottom rear of my buggy which I think meant it bottomed out as it caught the lip of the ramp.

Oh ya, the buggy was a DF03, which I think is a bit nose heavy to start off with.

Anybody else done this before? What's the best way to avoid it?
