I have the P-51 PTS as well. I have the flap servo and it does help. Still is a little harder to land then my arrow 40 though and I never had the speed brakes on mine. Only thing I dont like is the landing gear is so weak. My right gear block busted all up after only a few flights and I would say the landing was not that hard. Not the best but not that hard. Had to replace the plane after a crash and same thing happened again with the right gear block coming apart on the new one. The one big weak point I see in this trainer.
