SASLess, thanks for the info. It was the force trim release I was forgeting that was driving me crazy.
I am guessing that a "two-stage" intercom/radio transmit switch would work by depressing it to the first point to activate the intercom and fully to activate the radio (or the other way around).
212Man, thanks for your humor and praise. If you like you can always check on the latest at my site:
http://picasaweb.google.com/benchmark.avionics where I post public pictures of gauges and the model as I finish them. Right now as I'm working on the instruments, the gauges are what are getting updated everyday.
This project has taken on a life of it's own as I've learned more about a helicopter that I've never flown, or even been in, than I ever imagined. When I was in the Army I was ferried around on and jumped from many of them, but never imagined the fun of flying them. Guess I was having fun just riding on them.
It has been a joy learning so much about them, and one day I hope to actually learn to fly a real one. I do appreciate you all putting up with my unending questions.
As I learn more, the next project will be easier.
Patrick
