Kyle,
Thanks for your reply.I was wondering if i could change something in the aircraft cfg so i can omitt that effect.You know it's really impressive to see perfect frames while the a/c is on ground with engines off but when you start engines 1 and 2 (3 and 4 already started with NO frame loss),there comes the problem.
Anyway,Kyle i reaaly appreciate your help here.I would definately fly the Queen no mater what!!
