Your elevator is overly sensative, correct? I would double check the CG. If it's near the rearward part of the recomended range...or behind it I would move in forward. If the CG is pretty good (Smack on center or just in front of center) I would lower the travel of the elevator.

If you are using a computer radio you might try dialing in 20-30%.

Do only one of these things at a time and then fly. Make these adjustments in small increments so you get a feel for how they affect the performance of the plane.

Also, double check that each elevator half is centered in the same position and that they have exactly the same throw.

Once you get it so you are comfortable flying then you can concentrate on dialing it in, but as long as your afraid of the way it handles it's going to be tough to dial in anything.
