Got a bit more done tonight. I think I'm pretty well done with filling and sanding the bottom. I will go over it with finer paper before covering, but the shape is nice and smooth.

I started in on the landing gear setup. Unfortunatly, when I tried to bend the wire for the mains, both of them broke before reaching 90*. Either I will get new wires, or the axles that slide on to the end of these, I haven't decided yet. Adding the curve to the bottom of the plane made a bit more room for the main Retract Servo, but still is a very tight fit. I took a pic of a standard servo sitting there, hopefully the retract servo is that much shorter. If not, I can carve a bit out of the last rib in the wing, and the corresponding hole in the body to make the wires sit higher.
