Here is the original thread. Progress went pretty slow on it but I finally finished it. This was one of those projects that got put on the back burner for no particular reason.
The original toy had a fixed turret but I managed to fix that problem. The turret still hangs up a bit on the pilots hatch but it won't really affect it's play ability and it's still much more useful than having a fixed turret. I had to glue a piece of plastic pipe into the top turret and then I glued a piece of heavy cardboard under the turret hole with a hole in it to make the turret turn. Nothing on the conversion was all that technical so I'm not sure why I kept putting it off. It's going to serve as a medium hover tank for my Hell Knights army.
There are some down sides to these toys. There seem to be made with quite a few vinyl parts which will make them difficult to paint without dealing with off gassing. I think the Krylon "Fusion" paints may work the best. They are a good selection when painting any plastic toy and they seem to have worked out fairly well when I have used them on similar projects. Another issue is that they have very odd articulation. It's likely I'll pick a pose and glue them into place anyway but it's still annoying. They are also lacking in weapons so I will have to add a few to them.
