Hi Jim,

here is another entry from me for your DOM-Contest.

It’s the ‘Metal Invader’, a futuristic space ship. As the most of my own designed rockets, it is not very difficult to build, but I think it looks a little bit different to many other models.

I know small delta-shaped fins at the bottom and large fins at the top are not very good for stability. But so the model has an unique look (I hope so) and with a little nose weight it’s a stable flyer too.

Here’s the parts list:

Body Tube: length 305 mm; 25 mm diameter
Body Tube: length 150 mm; 35 mm diameter
Transition: 35 mm – 25 mm
Nose Cone: 35 mm diameter
Nose Weight: 18 grammes
Motor Mount: 18 mm
Launch Lug
Recovery Stuff: Kevlar cord, elastic shock cord, parachute (36cm)

Overall length: 580 mm
Weight: About 80 grammes
Recommended engines: B4-4, C6-3, C6-5

I painted it with metallic shining colours and applied some decals

I have pictures of the finished model and a successful lift-off, a Space-Cad file, a drawing and the fin and decal patterns for you.

Maybe you like it
