That's interesting. I never fly the Avenger as RAF so I haven't seen this problem. I went and experimented, and sure enough...you fly the TBF-1C as RAF, and there it is! The other one is fine.
So, I don't think that the answer is as severe as "don't fly the plane." Just don't fly it as RAF! One of the easiest bug solutions I've seen.
