The Joss Stick comes out nose heavy with a Magnum 1.08. I moved the battery to the rear of the radio compartment and it is still slightly nose heavy. When a friend of mine built his, I recommended he put the elevator and rudder servos in the tail. This gave him a good CG with the 1.08.

If you do use the 3000, here's what I would recommend:
1. Use dual aileron servos.
2. Use dual elevator servos located in the tail. I wouldn't trust a wood elevator joiner with a 3000.
3. Use pull-pull for the rudder servo.
4. Cut the nose off forward of the wing by half and fiberglass the firewall in place.
5. Fiberglass the wing joint.
6. Add bracing wires to the fin and stab.
7. Use good pinned hinges.

It will take some work, but it is doable. I have thought of doing it myself, just haven't gotten around to it.
