Purple,
I modified the bandito grande a lot to handle a gas engine. Sheeted the aft control surfaces with 1/16" balsa and mounted the servos in the back. The bandito builds very light and is a frame structure behind the wing trailing edge. I sheeted the inside of the frame with 1/8" balsa on the inside of the frame work so there wouldnt be any outside contour problems. I moved the firewall back 3 1/4" and made it out of 3/8" ply. I balanced with no led at all. Also moved the canopy back one fuse former and lowered the profile for a more streamlined look. I made a fiberglass cowl sorta P-51 style. The flaps and ailerons were increased in size to 2 1/2" wide. With all those mods, its ready to fly dry weight is 13 lbs 14.5 ozs. Attached is my stock built Bandito Grande and my modfied version. It flys great.
