Ross,
Nice pics. Would like to hear your pilot's report when you get it in the air. I have not built mine yet, but fly a good replica on G3, and I haven't had a need for dual rates. I would also be curious if any other pilot's have used dual rates or expo.

What is your motor/prop set up. You said it balances, and you just used the stock ballast, and a little weight in the cowl. I would love to hear your total weight since you achieved CG with the stock ballast. Good job!
