Unfortunately the rules have changed so I don't think the Pond Racer would be allowed to compete with the Unlimiteds.

1. The shortest possible route around the course pulling limit / max g turns around the pylons ?
2. A slightly wider route requiring less G in turns reducing induced drag losses and possibly a higher average indicated airspeed.
Thanks

Yes. It was called Miss Ashley II. Griffon engine with contra rotating props. Disentigrated right in front of our eyes while coming to the home pylon.

I was watching Extreme Air on cable last week which was about Reno 1999 and it was driving me crazy watching the pilot of Voodoo playing with the tweedle valve every 5 seconds , has anyone automated engine temp control for water injection now or are the pilots still spending 50% of their time playing with that tweedle valve ?

That rich enough for you?
