Contest flying, Sport flying, what's the fracking difference.....

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 have to wonder about this Boosted Bertha. The booster will surely come in ballistic - must be heck on the forward end of it.

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.

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.

I'm a little puzzled by the use of artwork instead of finished models on the linked-too pages.

I have such a huge back-log of kits that I'm not sure that I'd buy any of these, but the staged Bertha and the Double Ringer are neat ideas.

It would be neat to convert the Boosted Bertha into a Boosted RANGER with a payload section and 2 stages of 3x18mm cluster power.
