RE: V tail angle?

I, too, made that "mistake" when assembling a WACO Mosquito HL plane many
years ago. I called Frank Weston and asked if it would be a major problem.
His response was "try it". I did and the plane flew beautifully. Well,
it didn't thermal worth a darn, but I had no yaw problems.

Re: V tail angle?


Your margin for error has been reduced. But I do not think you will
notice any problem providing all else is 'true'. Regis
