on my jr 8103 I use a non multipoint mix #3 or #4 and mix elevator to flaperon about 30%, you will want flaperons to move in opposite dirrection of elevator - never in the same direction. In the old days we would mix in same dirrection to increase elevator effectivness -to do tight loops etc. 10 years ago a tight loop was a spectacular 3d manuver. today we have large elevator control surfaces and 45 deg throws = no longer need this. opposite flaperons really help 3d manuvers - when doing a harrier, when flaperons go down you increase wing lift and are able to maintain a high angle of attack at a slower speed much easier. when hovering and torque rolling prop air will push off flaperons in one dirrection and push off elevator in opposite directon it is like having someone holding the tail steady making these much easier. it is like slowing down the realism on a simulator. for a year I have experimented with more or less mix and had this on a switch, now I have it on all the time at about 30%, every airplane is different start with 10% on a switch and experiment. keep me posted, thanks
