When I first discovered the Diskhound kit (picture) in the 1980's, I knew immediately that it would make a great space fighter. Just remove the legs and the guns, flip it over, file off some parts and add a little putty. Finally add a cockpit and change the scale to 1:144. Here it is:
I had three of these in the 80's, built to reflect various stages of wearout. This time I only got my hands on one (as a "vintage" kit) and decided to build the middle one.
Front view with illuminated beam guns (using flourescent color).
Back view with illuminated engines.
Obligatory 1:144 figure for scale.
Yes, there is a cockpit and yes, you can open it! :)
