33% 260 engine box issues?
Hi Tom
I have a big problem with my 33% 260/ZDZ-80 RV-J/KS-95 canister. I have 11 inches header and it broke 3 times in 10 flights. I have tried tig welding and i replaced the flexible part by rigid header and the last time, it broke at the exhaust flange.
I spoke with an IMAC pilote today who got the same problem with another plane and DA-100. He solved it by reinforcing the engine box. It reduced the vibrations.
Have you already met a problem like that or do you have any recommendations before i modify the engine box?
