WARNING. On the first flight of the day (10-12 flights in total ), I noticed some serious flutter in the elevator of my Yak 54 (52) 3D.
Landed immediately & on inspection noticed that the stab wood had cracked on both sides of the elevator just where it attached the fuselage. I had used 30min epoxy & made sure NOT to cut into the wood while removing the covering etc
Anyway I will have to cut the covering from the bottom & CA the whole thing besides adding some support to the stabs.
just wanted to warn any owners to keep checking that...
