Trying to shove bombs and missiles on a plane and still takeoff is very difficult. Is it easier to fly with FAR because it was seemed really weak in stock settings.
See as how the falcon is almost a direct copy of the F-16 now, and chance for other put together planes like a jigsaw puzzle COUGHF-18COUGH I spend hours trying to make it just to crash and it REALLY kills motivation to play when it does and even when it doesn't it doesn't like to fly.
What I think would be a really neat feature is the ability to generate a random path, from say KSC 1 to KSC 2 with random changes in elevation and maneuvers, but maybe always keeping a set altitude above the ground.
