Eric, I am building the Testors HH-43 kit. I'm about 90% complete. Added stringers,longerons, vertical tunnel, back step area, seat, wiring, fuel tubes and few other things to cabin. Added overhead panel with circuit breaker panels, rotor brake cylinder and handle, wire bundles, etc in cockpit. Added exterior cable and tube bracing, jack points, antennas, drians, pitot tube, HF antenna wire on exterior, and cut out xsm screen openings, and engine intake and covered with brass screen. Need to try and come up with landing lights. Right now I'm stalled because my Future spay job came out poor, and I broke off the left side vertical fins. I Have two kits from Testors. Early kit came with decals from Italeri. The star and bar insignia seem to be the right size but the decals fall apart in water. The sheet is a combination of a little military and the rest civilian. Really poor. The second kit decals are from Scalemaster and are military, but the star and bar seem to be to large. I need to find a decal sheet that has USAF and numbers small enough to fit the vertical fins and some star and bar insignias. My references are some photos of the bird I crewed in Viet Nam S/N 59-1590. Becarefull with the tail it is fragile. Good Luck with your build. Scat
