A Progress Report On The New Plane

I've got a lot done, and the pics tell the story.




The fuselage was built on a pink foam "crutch".





The wing is complete, except for aileron servo installation.

Wing Building

Still flying the same planes but new Admiral batteries from MotionRC  put new life in the FMS 800. I'll probably order my next plane from them. Meanwhile I'm trying yet again to build a good wing from cheap materials. Latest effort uses Dollar Tree foam board. I find that the stuff with color is straighter. So I used that plus pink foam. A 48" strip of pink foam cut to a width of about 3 inches makes a center spar. sandwiched between sheets of foam board, the result is quite rigid. I'm using carpenter's wood glue. No spar is needed for a straight wing this size. The airfoil has a flat bottom. I'm using balsa triangle stock for a leading edge. Because the foam board is not long enough a full sheet makes a center section and the tips are added in separate pieces. When everything is glued up, vinyl packing tape will be used for reinforcement. Balsa trailing edge stock will make ailerons. The plane I hope to build with this wing is going to be along the lines of an old Ugly Stick, and I'll use a motor from an old, crashed, FMS 1280 and an upgraded prop. The motor will be up front in a tractor configuration. The wing will be spray painted with  Rust Oleum. The fuse will be a contrasting color. I'll post some pics soon. You could use these materials to make a symmetrical airfoil as well. Dowel or arrow shaft could be used for a leading edge. This plane will probably not use landing gear since I hand-launch everything and land in tall grass. I will probably just use aileron and elevator.
