I have a project that's nearing completion, at least it will be once I get my mojo back. It started out as an ICM OV-10A Bronco in 1/48 scale, and I've done some conversion work using scratch building, 3D printing and vacuform. Here is the model as of tonight: (note: if you don't see the image it's because your browser is blocking it. It works on Firefox.)
The build was coming along nicely until I hit some bumps in the road. The first bump is that the propeller blades are set at the wrong angle - they should be in flat pitch (blade angle = 0). No manufacturer of OV-10 kits has ever got this right, so it's hard to fault ICM for this. If I squint I can pretend they're at flat pitch.
The other road block was the decals. I really should sand them off and re-do them, but I don't have enough mojo left for that. From a distance they look fair.
The most arduous part was building the kit without the sponsons. This required sanding and filling the recesses for the sponsons, then scribing over them.
3D printed parts are: jet engine pod, ILS antennas, 230 gallon external tank, main landing gear, winch operator's seat, and a mold for vacuforming a clear cargo bay door.
To do: install winch operator's station, finish and install cargo door, finish decals
