Using G2 latest version I have created a GP Corsair F4U. I have used the data from the GP prints and specifications.

The Corsair simulation will take-off if you are careful and do not add too much power. Once airborne the plane wants to dive, hard over instantly. With enough altitude the plane will end up upside down and fly that way... for a while. I must have something wrong but I can't find it.

Suggestions, hints, ideas all welcome.
