Another option would be to have the 24mm tube stick out from the main BT and glue strips of balsa to it to simulate the ridges on the original tailcone. Since it's painted black it would probably look pretty close.

Exclamation Updated RKT File -- 1987 Catalog Parts Demo

Attached is an updated RS8 version of the 87 Catalog Demo. After seeing what Geoffrey had in his RKT file, I now understand a little more of what he was doing. I also understand now why he didn't see my tube fins when viewing the file in RS7.

When I whipped up my RKT file, I took advantage of RS8 having a "Tube Fin" feature, which RS7 doesn't have. RS7 cannot recognize the script, and so it omits trying to draw the tubes. Geoffrey used a simple "inside tube" approach, which is all that RS7 offered. I can see his RKT file completely, but he cannot see mine because of the RS8-specific scripting.

Cool. I like how the little dowels just float out in the air. Less drag that way!

Exclamation New Plan -- Kryton

Here's another ring-fin, this time for 13mm motors. The A10-3T is the only recommended motor for this design, as the A3-4T deploys the parachute at too high a velocity. The maximum altitude is only about 190'.

Skill Level 2...

Schoolyard Sounders series.

Exclamation New Plan -- Aerobee-Hi 60

This plan is modernized and updated from a design I saw about 15 years ago by Pete Alway, in AmericanSpacemodeling magazine. His design was intended to be a gap-staged full-stack Aerobee-Hi, using a BT-60 upper body and a BT-55 booster. His original design was truly gap-staged, with a wide open area between the stages, per the prototype.

The BARCLONE version is just the upper stage of this stack, as I don't have the drawings for the booster available anymore. This version is a 181% upscale of the BARCLONE Aerobee-Hi, which was itself a 10% upscale of the original MMI-EIRP version. This model uses a SEMROC turned balsa nosecone following the dimensions of the currently-OOP PNC-60RL. (Please note: The SEMROC version also doesn't yet exist, but I'm hoping our good friend Carl will see his way to replicating it and making it available on his website).

Skill Level 1. Not a difficult model at all, in this configuration.

Flies to 900' on a D12-5; 1936' on an E15-7; 2336' on an F21W-8.

Respectable performance, I'd say...

Enjoy!

Sweet Craig. I can get you the booster dimensions, but you're going to have a helluva time with the interstage posts. I'd just go CHAD and make it one solid tube up the sustainer.

Pete built this around the same time I built a gap-staged Standard Missile 2 ER. Both models staged well except when Pete tried a B4 for the upper stage once and it didn't ignite. My SM-2 had the problem where the booster was stable after staging and cored in most of the time. That lead me to work on some gap stage booster recovery ideas.

Exclamation New Plan -- Cormes Protectorate Drakken Defender

Long title, but a good performer on a B6-4 or a C6-5. The Drakken Defender is a "family member" to the Empyria, Rampage, Scorpion, and Spectre.

Skill Level 3. A PDF of this design is almost ready, and it contains additional detailing pieces; the wing tips are 1/8" dowels and there are some small fins that are attached to the engine pod tubes.

(Cormes is pronounced KOR-meez...)

Thanks, Buzz. I could use them...

I remember the AmSpaM article, and Pete's construction method of using a JT-60 coupler epoxied to the struts; I'll probably just "borrow" that method, unless I can develop something more rugged and stout. If his method worked reasonably well most of the time, it still will...

Craig, I dig the design a lot, but the name makes me wonder when you'll have a black and light green design with "She-Go" in the name. (Those of you with kids will understand)...

Later,
EV
