Here are my two new assembled HS38 Rockets by Bombshell Miniatures. I'll call them the X-3 and X-4 models (three- and four-engine, experimental.)
The conversions were very easy owing to the nice resin. I sliced off some wings, filed down some edges, drilled a couple pinning holes, and added a nose cone with some green stuff. I'll give the glue and green stuff plenty of time to cure, and will start priming tomorrow.
I should have ordered another pilot so I could put together this nice little Scooty Puff Jr. model.
Update: I almost forgot to do one more thing to my X-4; I clipped the wings. I wanted it to have less of a "flying" look and more of a "speed" look. And these ships are mostly supposed to be flying through space, anyway, so there's no need for wings. (And yes, the pilots aren't wearing pressure suits, but I prefer to see them in the spirit of retro scifi, when all you needed was a leather jacket and a gas mask to survive in space.)
