Bud,
I think that Dan has 3 places he can fly his jet. Our field, Brodak's and the nats. Even so you can wear out your welcome with a steady onset of pulse jet noise. A jet may be novel for a flight or two,after that it's just really loud noise and can make you about as welcome as a bad cold. Dan averages about 4 flights a year at our field, Brodak and the nats a few. I don't think that either John Brodak or the Flying Dutchmen field could withstand an onslaught of pulse jet noise and escape any form of criticism from surrounding neighbors.
All of the other concerns raised are valid and it just reinforces why your not seeing them used except in one event in speed or experimentally and flown at remote sites like the Arizona desert. Having seen Dan's jet fly from the first flight I can say that while it is an impressive achievement I wouldn't exactly say that it is any challenge to the average stunt flyer at any contest. You don't see jets at any serious aerobatic events in the world, Humm, I wonder why. What! you mean that it can't do a snap roll?
What I'm saying Bud is that there are more rewarding projects to undertake than a Dyna jet stunter that no one really needs or has no place to fulfill it's function.
So when are you going to make it back up to the hill and get some handle time?
Dennis
