Bokuda, Looking great!

Just some food for thought:

The servos as per the plans are the ticket to getting the plane to balance close to CG. The servos in the tail weigh about 3 ozs total for the 2(one per stab Half)
The 3 ozs in the tail equals a weiglt loss of "more" than 8 ozs you must have in the nose section to maintain CG location.

You used a lighter engine than the plane was designed for, so you helped your problem there. Maybe you can work out installing the dual servos in your stab halves, or move the elevator servo to a bottom of fuse, hatch accessed, about 2/3 down the fuse towards the tail. That would save you some of the weight you are going to have to add to the tail.

I have not heard of any misprints on the CG. I guess its all in how you want a plane to fly, and how you like it to feel.. The CG range may be that large to be able to move it around an inch or so and still get good flight characteristics.

The one improvement I have heard of is smaller wings and stabs, with some sweep forward on the TE. Suppose to improve the snaps and spins.
The 1100 in wing cannot help but be stable. Too stable for some I guess.
