Put the Double Ringer together tonight - takes about 45 minutes and you need scotch tape, plastic cement, and scissors. I used medium CA to glue the plastic fin unit into the body tube.
Very interesting looking bird - hope to fly it soon.

Nice to see the Phantom back!
Like the Two Stage Big Bertha to. |

I've seen this configuration several times over the years. Seems like 40% off coupons at Hobby Lobby and plentiful Baby Berthas led to many different bashes, some of which were stagers like this. But I can't see that booster tumbling in, not unless weight is added to the fin tips. Doug .

The booster on the Bertha does in fact Tumble.

If you follow the Boosted Bertha link posted above, there is a link to “Download Instructions”. Besides having moderately larger booster fins, it has a screw-on motor retainer (as does the upper stage). With that added mass toward the aft end, it looks like it would tumble or possibly come in fairly flat to me.
Two features I really like — booster venting thru centering rings, out the aft end, and TTW booster fins. Looks to be a fun rocket.

The Double ringer gliders are rolled from card stock so lots of replacement decoration options are possible.

How about a 29mm bigger Polaris or Comet. 3"? |

A few things from the forum at NARAM last night - a new boost glider that appeared to have some Shrox-like characteristics, a single stage SAM 83(?) that looks like a companion to the Sasha, confirmation that the current BLACK POWDER 29mm motors are as big as they’re going to get BUT a very strong hint that more powerful PSII motors are coming, and that new PSII builder kits will be upscale versions of classic Estes/Centuri designs. Plus it sounded like B14s are coming back. Oh, and a little fly and forget mini rocket called the Luna Bug - think Mosquito with curved footpad equipped fins.
