I run mine with all the stock hardware, and it's built by the manuals directions. I run standard servos. I have a Saito .91 on the nose and my CG is right around 6 1/4. Landings are a bit nervey because of the tail heavy characteristic, but they always come out looking pretty professional. I removed the blind nuts for the landing gear mount and drilled out the holes and tapped them for 1/4-20 nylons. I also added two more bolts, one at front center and one at rear center. Before flying it, I added a good bit of medium CA around the inside of the plane in the landing gear mount area. I also added some to the inside around the firewall area.

I have yet to have a problem with this plane. It is a bit snappy when using lots of throw on the elevator, but that should be expected. The more tail heavy it is, the better the 3D characteristics, but the crappier the landings. Every bit of added weight makes the elevator that much more sensitive, and the plane that much more snappy.

Like I said, mine is totally stock and I've yet to have a problem.
