I owned and flew a Rotorway Scorpion for about 60 hours then sold it. Now I love my Mosquito.
I live in Arizona where it can get to 50c (122oF) but I love it. Always good flying weather.
I've been heavily involved in pressure jet helicopters, having been a good friend of Dr. Bruno Nagler, and received two patents on a higher efficiency version (e.g. #4,702,437)
I'm also interested in alternative free energy research and new kinds of engines (see Joe Cell on Internet).
