[Bugreport] FMs (Various)
 

Spitfire (all var.), 109 (all var), Hurricane (all var):

Structural damage does not degrade climb and speed performance when able to hold straight, most noticeable when one of the wingtips is shot of.

109-B:

Bombload does not affect topspeed, apparently the bomb does not produce drag.

Spitfire Mk1a:

When going from pitch fine to coars, below 2000ft the RPM will drop below 2100, giving fairly heavy vibration. No damage to the engine.
