I removed the 2nd panel from the shucks and everything looks good. I am finished working on the Chipmunk for the day, the wife and I are going to spend the eveing in the Home Theatre watching movies. Tomorrow after work I will shape the tips and figure out exactly how I will handle the aileron's. Looking at the plans it looks like I will have to move the firewall back a little to accept the 52 4-stroke. I have a friend getting me a measurement since I do not have my engine yet.
Later!!
Anthony
ps. Thanks for the tips!!!
