The problem that I have is engine power of this model is too much.For example , ready for take off ,weight at 27500 lbs, I apply power slowly and when the throttle is at about 80% the power increases so much and if I release the breaks the model behaves like a rocket and in seconds the speed is at 1000 kts.Imagine what happens at 100% throttle.Platform fs9 , win xp home.Any ideas?Thank you for your time.
