Corkscrew 2 Build Finished!

I sprayed the nose cone black to give it a better color balance.

What an easy fun build.

This was a true budget model, all spare and leftover parts.

I've already got it loaded and ready for flight!

Followup:

The Corkscrew has flown four times since this build was posted. All stable flights, with a 1/2A3-2t and A3-4t engines.

It was just personal preference, but I ended up cutting off 4" from the bottom of the BT-5 body tube. This involved cutting off the lugs and ring. The old Kevlar was tied to a new engine block and the block glued in place.

I felt the model would look better a little shorter, closer to Bruce Levison's original design.

The picture at the right shows the shorter version.

In the end, I found out the .40 oz. of nose weight wasn't needed. It made the model too stable and caused it to corkscrew less. Without the nose weight it does corkscrew more during boost, you can easily see it in the spiraling smoke trail.

Thanks to Bruce Levison, a great simple design - different is good!
