My plane crashed.

I was flying at about a 45 degree dive, direclty towards myself, about 50 feet altitude, wings level, and pulled back on the stick and rolled to the right.  At that point the right wing detahced rather viloently.  The right wing drifted gently to the ground.  The left wing, and the rest of the plane, drove full throttle directly into a rail on a rail-road track (about 100 yards behind me.)  I cannot think of anything harder to run into than a steel rail. 

Aside from the wing being split in half, the damage was extensive.  Pretty much everything forward of the CG was no longer connected to the plane.  The plate holding the Servos was detached, and hanging by bent control wires.  The engine, landing on a different side of the rail than the rest of the plane, also attached in a general sense by control wires, appears to be okay.  The muffler leading edge is dented, and I couldn't find a splinter of wood from the prop, but the engine feels okay (it resists spinning with the glow plug in, but spins smoothly with the glow plug out.)

The throttle servo lost it's top, and will need some parts, at least. 

The right wing is in great shape.  The left wing took a big hit and may never be repaired.  If anyone has a left wing to a SIG Kadet LT-40, I would really appriciate knowing what they want for it.
