I've been to two of the races myself...to say I was in awe of all the planes and their crews is an understatement! As impressive at it was to see these planes doing in excess of 500 MPH around the course, I've gotta say watching the crews work on the planes in the pits was equally impressive. Also amazing is seeing all the mods these guys have done to these planes...getting double, and in some cases, almost triple the HP out of these engines as compared to stock AND getting them to hold together long enough for a race seems like a magic trick to me. I don't know how they do it! I'm looking forward to going back again some day...and to discussing the subject...
