Thanks. I appreciate your insight. Interesting choice of terms: chopping and hacked away at it. I'd have prefered "amputate" but I got your aversion to shortening the boom.
I purchased a Dynon pitot boom and built a reciever into the leading edge of the wing on my experimental Champ. The boom is greater than 12" long. I would like to shorten it. Any advice on this? How far does it need to extend to be effective?
