Thanks CW46, We're having the tip over on taxi problem. Fly off grass. Unless cut very short, taxing is a problem. I want to balance it as far to the rear as I can without making it snappy. Bought it built so don't have plans. Thanks for your help! WLJ

Center of gravity is 5 1/2"- 5 3/4" behind the wing leading edge measured at the wing root.

FWIW - Suggested control surface travel:

Aileron - 7/8" up and down
Elevator- 1 1/8" up and down
Rudder - 2" left and right
Flaps - 85 degrees


Love those trucks leaving big boxes.

Status: offline 		.02 cents, cg the plane more forward than aft. It looks deceiving, with that big root chord, but if you get tail heavy or even aft, it becomes a very pitch sensitive airplane, more so than any plane I have ever flown. Set it toward the forward suggestion, and you have a rock solid airplane that can hold a straight line for you all day long, to the point of boredom!

Enjoy it.

Ray

Status: offline 		Just finished my 13th flight on my new Yellow Spit and mine is balanced 5-3/4 from the front of the wing. My take offs are done with full up elevator off grass with a gradual decrease in elevator as the speed picks up. Very little up elevator on the hard stuff.
G-38 for power and a 18-10 Pro Zinger(7400 rpms) and it weighs 25 lbs. 2-1/2 lbs of non cc material on the firewall
Speed is very fast for such a small engine. I do notice the speed bleeding off in my steep climb outs after a low fast pass though.
I love the way this aicraft flies! I cant say anything bad about this bird.
