Dave,
Thought you knew of the elevation noise problem. Yup, can't fire when the elevation or depression sound is going. Most guys are using 5+ channel radios and
have it mixed into different channels. To stay with a 4 channel set up you'll need to get a camera mount servo delay. It slows the servo, but also stops it in positon so you
don't have to remove the self centering stick. I learned the hard way as well. For years I was doing elevation/depression fan shots with my PZ III since I had to elevate, let go of stick, then fire before my
barrel got off target.
