Geez - dntmn - Looks like everybody is tired of the pizazz. Your plan looks good. I've used both the Sato 72 and the YS63. Can't see much difference in flying. 13/6 APC definitely outperforms every thing else I've tried for this airplane engine combo. I started out with my cg at 3 3/4 and moved it back to 5 inches in 1/4 inch encrements. I settled on 4 3/4. At 5 inch the plane was manageable but unstable in pitch, very touchy to land even on low rates and the pitch rate during flying seemed to be a little unpredictable. It didn't seem to follow stick input real well but I'm not using the best servos for this thing either.
I set up the control throws and expo per the instructions except for rudder for the first flights. I don't have dualrate for rudder so I just went for the max without it hitting the elevators. I would make first flight on low rates and the cg at about 3 3/4 just to make sure what the plane wants to do. If it's like mine it'll fly fine but won't do much. High rate on the elevator is about right for normal flying. Low rate on the aileron is way to low and high rate turns the plane into a drill plus in my opinion tends to kill manuevers. I finally settled on a throw about half way between low and high and maybe a little closer to high on the ailerons. The high rate elevator is not enough for reliable water falls or flips. Mostly you get a very tight stalled loop but not a tumble. I'm going to make my high elevator throws my low rate and go to the extreme on my high rates and see what happens. It'll give me a little trouble landing in a wind but that's OK. With flaperons I'm using 75%. I can't really say they do much except they seem to help with a hover, and need to be turn off when landing. I think I'll go to 100% and see how the plane likes that.
This plane is not really a "fun fly" but more of a fun to fly that can do a lot of stuff. It's too quirky and heavy for a real fun fly.
