exactly, at first they begin to get loose on one side, then the vibration makes the rest!
compared to other engines like the tr for instance, the fins are thinner, that could be the reason.
on a crash the fins brake inmediately, not so here, had to use poxibonder (kind of metallic pot) to avoid one fin to continue to get loose by vibration!
