Hello flyers, I have a 55" midget mustang (not a motion plane) but have bought from motion allot, at any rate, this plane has flaps. I need some advise as to what percentage of down elevator I need to what percentage of down flaps on the mix. I have a rx6i, I maidened the plane today, and what I started out with on the flap elevator mix was 50% flaps and 15% down elevator, and when I deployed the flaps at about half throttle, it ballooned up on me. I changed the down elevator from 15 to 30% but haven't tried that yet, perhaps some of you p-51 flyers can give me some settings to try, or some advise on this? Thanks 505 flyer.
