banktoturn,

There is no racing in my area anymore, I wish there was, I really enjoyed it.

You might try posting over in the pylon world forum to generate some interest in your ideas. You would atleast get some good feed back on whats allowed and whats been tried leading up to current designs.

Also take a look at the Pylon world web page, especially the Q40 planes, I think the are averaging 180 MPH in a 10 lap heat.

PAINLESS
