Big Blinka
#1
Here's a scratch build that's so far only in primer, but I'm going to fly it Saturday anyway. After all, it's not meant to be seen in daylight. Big Grin  "Big Blinka" is a night launch rocket.

How did you accomplish that? It is really cool and I wouldn't mind copying your build sometime in the future when my build skills improve more!

There are details here:

I used a light-up foam baton party toy, 6 for $8 at Amazon. Added more LEDs to the top end and the nose cone. Stiffened the foam with a clear plastic tube up the middle. The tricky aspect is gluing: Nothing I found seems to want to stick really well to the foam, but I found JB Weld Clear seemed to be adequate especially with some holes poked in the foam's surface. If I were doing it again I'd change the design for how I did the bottom end of the upper section; as it is I'm just hoping it won't pull apart at ejection.

Ok... Here's my thoughts...

Sandwich the foam (no glue) between sections of body tube that are held in place with centering rings and/or tube couplers. The CR could be secured to the clear tube with masking tape, or medical paper tape. The tape would give the glue something to bond with.

Launching is Optional... Landing? That Depends on Trees.

Sharp looking rocket Rich! Hopefully I will be able to catch that at a night launch sometime..

I painted it. Black. Great color for a night flyer, right?  Rolleyes  Well, a lot of it's still white; there's a chance of seeing it even if the LEDs fail.
