Good question Jim. The answer is no. I've been in RC since 1952 and it was the reason I became an electrical engineer. My father spent a fortune on me so I could accumulate all my degrees. Luckily I speciallized in radio frequency engineering including the microwave region. I don't claim to know what I am talking about but I may be ahead of the doctor, lawyer, plumber or someone else that did not get his brain shrunk trying to memorize all that stuff for six plus years. Notice, I said "stuff" instead of something else because all I wanted to do was past the tests at that time. I probably forgot more than I learned by now but I can help the guys in this great hobby of ours a tad more than someone else. Experience does count but it's a tough way to learn. You never want to defy the laws of physics because you will never get away with it in the long run. And that usually happens when we are flying. Suburban is lucky. He found his problem before he got off the ground. Dan.
