Carletto,

Test flow the cap over the weekend and overall impressions are very good. Surprisingly good in fact. I ran an apc 13 x 6 and 12 x 7. The conclusion is that the high speed of the 12 x 7 doesn’t do much for the flying of the plane. I think I will keep the 13 x 6. The vertical was unlimited and thrust very good. I had rates set to the recommended, and high rates 45 degrees, up and down, on the elevator. Double for ailerons and max deflection on the rudder. The plane will snap out of loops on very small elevator deflections!! The high rate was set-up for spins 3d etc. The flat spins were very flat, almost no decent with the power on, Blenders, were very good. Snaps very snappy. Knife-edge was doable, but the conditions were windy so no real conclusions about that, but it did climb on knife-edge. The rudder is very powerful and slows the knife-edge down very quickly if you use too much. I didn’t try a knife-edge loop. The Y push rod is holding up well and the plane doesn’t skew out of loops. I haven’t weighed it yet but I would guess about, or just over 5lbs.

So in answer to your question I think that servos in the tail for the elevators are over kill.

Good luck

Kris
