I suppose the whole idea of this glider was to look cooler than the space plane. And we need a place for the pilot, right? There is also the wee problem that the 2" payload section gets reduced to < 1/2" after the 2 shoulders & screw-eye. Hmmm, a grashopper decal might be in order...

You could increase the size of the payload section by cutting back the nose cone and bulkhead shoulders to a bare minimum.

You could also hollow out the nose cone base, allowing the weights to be placed well forward and perhaps friction-fitting them into place.

Even so, I suspect that payload capsule is pretty much cosmetic.

Dang, I am so excited to finish this and see it fly. Going to a big field this weekend for a kite festival. We will be first on the field so I was thinking of getting a launch or two in before the crowds (10k expected this year). I, however, hate to fly em unfinished, and am now back at work and not getting home until after 9. Can't have too many late nights.

I think I can pull it off if I drop the other 3 that I am working on.

Default Just finished my X-21

This forum was very helpful with this build. It helped clear up some of the gray areas I had reading the "small print" instructions. Anyway, here she is

Thanks, and nice looking X-21. How'd you do the checkerboard patterns?

I launched her for the first time today. It really was too windy, so used a 1/2A6-2. The wind really messed up the glide, well at least I didn't have to walk too far. Here is a launch pic. I'll try again next weekend at the WOOSH vintage rockets theme launch.
