To bring this back to the original topic (I know, spoilsport ) - I received an order from AC Supply today that included examples of both the new Boosted Bertha and the Gryphon glider, but also three Phantoms.

The new version of the Phantom is complete except for adhesives. It even includes the wadding. The cutaway motor is pre-made so none of that cutting out the vacuum-formed part and painting it. The body tube is 5.5 inches long, so it builds up into a model exactly the same size as the Alpha III.

The new clear fin unit and nose cone are not quite as crystal clear as the 1207 Phantoms from “back in the day” but have a very slightly frosted appearance. This won’t detract from the purpose of the model.

All in all I’m really pleased to see this one back. I’ll be giving one to the Museum of Flight for use in their Amelia’s Aero Club program and one to South Seattle College for use by their rocketry club and newly-created NAR section.

I’ll post a side-by-side with a vintage Phantom after I assemble this one.

The Boosted Bertha uses the new 18mm screw-on motor retainers, which is a nice touch.

Speaking of which, I got a couple of packages of those in this order as well - three sets to a package. The retainer is pretty light - 2.3g for a set, which is 0.9g heavier than an Estes motor hook (the one from the new Phantom, to be particular). A quick dry fit with a model in progress on my workbench says that if you put a motor block in the usual place (for a 1/4 inch motor overhang aft of the tube) these new retainers will be perfectly situated. The motor will protrude 1/8 of an inch aft of the portion of the retainer that you glue to the motor tube and the retaining cap has plenty of threads to go on about two turns and then snug down against the motor. Nice.

I'm going to build a new Phantom just to launch it to ruin the tube with nasty looking orange ejection junk.
When in doubt, WHACK the GAS and DITCH the brake !!!

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.



As John Boren noted the Boosted Bertha’s booster does in fact tumble very nicely. I now have four flights on mine and the first stage has tumbled as it should (and landed relatively softly) every time.

No weights on fin tips. The booster, however has substantially larger fins than the sustainer (which has the same planform as the current “regular” Big Bertha). It is also gap-staged and has a 4.5 inch long body.

Attached is a frame grab from the maiden flight video. It doesn’t show the booster tumbling....but it certainly does.
