RE: 1/2 Pylon Video
That looks like a bucket of fun, thanks for posting the link.
As to your engines, I have heard a lot about your racing through Toad. As a rank outsider, it would seem to me that perhaps you should consider allowing an engine like the fora: are they still $140? You might get more even and consistant racing and have everyone spending more time in the air.
Mind you, if those piccos can be made to hold together, they would be great engine to base a class on.
