ORIGINAL: cutaway
... I think I'm going to have to limit the throws on the elevator down to maybe 30 degrees. The ST C35 was running well on the GRW tank, and with 3/4oz of lead in the nose it was grooving fairly well with no tendency to hunt.
You can move the control spacing closer together at the handle to limit your movement. Then check where you get the best response. This way, when you change them on the plane, you know where to set it. Make sure you NEVER hit the limits on the plane before the handle or you will put undue stress on the plane...especially the elevator.
My Magician hunts and it annoys the heck out of me, maybe its LE is too blunt?
More likely it's something else. Check that the balance is not too far back. CL planes balance about 25% behind the leading edge of the wing chord (forward from most RC balance). The more forward, the more stable. Next, check that the wing, stab, and engine are set parallel to the center line. Most affect is wing and stab not parallel.
Good luck.
