CG Ultimate Control Throws
I hear you on the weather thing. I'm in Wisconsin and still under a foot of snow. I fly the Zagi a lot.
For your throws, I do fly a lot of aileron. Other good pilots in my club have taken the sticks and commemted on the "CRISP" aileron response. You may want to back off a bit, or add some expo to start off with. I also agree on the light rudder throw. This plane has one of the best rudders in the hobby, use it. Start off with 2 1/2 inches and work up to all but touching the elevators.
How is balancing the Saito going? Unless you moved servos to the tail, you'd better go buy some lead. My Webra (31 ounces with a muffler) took 3 ounces in the tail to get it to balance by the book. That was with the Rx and battery under the canopy. And I still feel the CG could have gone back quite a bit more. If I did another, I'd put the servos in the back.
Good luck, keep us up to date.
