RE: Sig Wonder
Mike,
I had to mess with my CG quite a bit until I got it just right for me. I'm on the aft edge of the recommended range. It makes the plane pitch sensitive but I'm used to it. Start with your CG on the forward edge of the recommended range. Adjust it until you are comfortable. I sure miss the rudders sometimes but do not personally feel it is worth the extra weight, If someone tries it out let me know. These planes are a blast. I have flown it in 20-30 mph gusts. It penetrates great and floats in for that nice skid every time!! Have fun.
