@eness76 Great looking planes and great post! Why do you suppose the triplane flys so much better than the biplane? What would you do on the next build to try to make the biplane fly better?
I’ve moved the CG farther forward on the biplane than the recommended position and Really reduced the rudder throw below recommended and it has smoothed it out considerably, but it is still not as smooth flying as the triplane. Everybody’s will be different, but I’ve added 1/4oz to the nose and have the 850 pack slid out almost to the prop. Being rudder control, it’s very unstable as it transitions from level to banked wings. Once banked over its great, but that transition back and forth is a little jerky and unstable (Think tippy), while that movement is very dampened on the triplane, probably because of the additional lift. I don’t miss ailerons on the triplane at all, it flys wonderfully smooth. I wonder if increasing the side area of the fin slightly would help, but I haven’t bothered testing. I have the Se5 to a point that it flys fine and is fun, but adding ailerons to the bottom wing would probably make it more fun. If starting over I’d probably add an aileron servo, and reduce the dihedral. Lowering the top wing a touch would also reduce that tippy tendency a bit too, I believe.
