I am currently scratch building a JAR. I have only seen pictures of a few and decided to try one as I've heard they fly and hover well. Well, the plane is built, I just need to install the servos. The dimensions are 18" wide by 21" long. My control surfaces are 3.5". Power is going to be a LittleScreamer on an Etec 450mah 2cell with 8x4 GWS HD prop. GWS 4ch Rx with 3 Hyperion 3.7g servos. Here are my two questions.

1. CG (I am thinking about 5.25" back from the nose. At least a good place to start. To achieve this, the radio and everything will be in front of the CG)
2. Control throws. I don't want to have it too touchy so that it is unflyable, but have enough to fly the plane.

This pic is of it early on. I'll post more pics later.
