Sometimes, it's better to beg for forgiveness, than to ask for permission . . .

I have a new Semroc Spaceman kit from eRockets. It's been redesigned and includes recovery. I haven't slit it open yet so I don't yet know all the details on how it works.

Hmmm, I didn't realize this was offered as a redesign. I see it's 13mm too.

Yes it is 13mm--so you may actually get to fly it twice! :rolleyes:

The new kit has washers to destabilize it to cause it to tumble. Those are not called for in the original plans so should be a help. Laser cutting the fins with interlocking pieces and the alignment guide should help with the up part for the new kit. It looks like a big improvement.

I never built an original, but the Semroc kit is very nicely executed. The arms and legs interlock with the “jigsaw puzzle” interlocks. They are slightly different in shape so you can easily align the pieces visually. The alignment jig also helps hold pieces in place correctly as it is glued together.

My friend Pat Easter's 10X upscale Spaceman flew straight on a M2000 at LDRS 31 https://youtu.be/H6MisplYpXU

Unfortunately he forgot to attach the recovery device to the airframe.
