John, defiantly the clunk. Unusual setup with the tank in the wing. First time I flew it everyone gathered around to inspect. Real thick chord on the wing really accentuates the noise. Wouldn't bother with it if I didn't think I should check the lines anyway at the start of new season. Been flying it that way 2 years. Kinda annoying to keep getting asked about "what's that noise". Lol

Probably just try wfrapping the clunk as suggested earlier, cheaper and quicker.


Pulling out all the birds and going over them as the good weather approaches.
