RE: VQ FW190
On my Hurricane, I'm using the 90 degree retract angle, because the wing is basically flat with no dihedral. On a FW-190, I believe there's is some dihedral, so you would want to use 85 degrees. That being said, before someone tells me I'm wrong, the "Real FW 190 used a retract with significant less retract angle. I believe around 70 degrees. However, this being more of a sport/stand off scale plane I would go with 85 Degrees.
