If it has a 24mm mount, a RMS 24 D15, E18, or E28 would work along with SU 18mm D10, 18mm D24, 24mm E15, or 24mm E30 should work.
You better have good glue joints with the D24, E28, and E30 though.
I have seen as little thrust as an old Composite Dynamics E20 rip fins clean off with poor glue joints.

I have an original Antares in the box. When I build it, I'll either go 24mm, or more likely, a 2x18mm cluster. It just looks like it'll be way under powered on the recommended B4-2 or C6-3.

Bill,

Have you considered doing the Orbitron ? I can't imagine the outside pods would hold up very well to landings but it sure is a cool design.

No, but someone else did it a few years back. I think you're right on the pods. They seem like they'd be in the perfect spot to be damaged every flight.

I, too, have a Canaroc Antares kit. The blow-molded nose cones are quite rough with a lot of flash. I saw the Sunward kit at a local hobby shop and knew it was an clone in a different scale.

Had to get the Canaroc Antares kit all those years ago as my daughter's name is Antares. I was an astronomy major until advanced calculus made me an Air Force missile technician. My now 40 year old daughter has a almost-three daughter of her own. Still cloning an Estes Antares kit with parts from SEMROC so that I can give it and an original Estes kit to Antares.

NEVER have understood a 2x18 or any other 2x cluster.
A 2x18 max would be equal to a D12 unless using composite D10/21/24 motors.
A 3x18 cluster makes some sense as it will get one more total n-sec than a single D12, or if using composite D's, it gets one 60n-sec.

I would go 24mm as there are lots of options there up to the 24mm 50n-sec RMS F24 or F39.

The Orbitron looks cool. Was that ever produced ?
I seem to recall that was catalogued but not produced.

I have a couple of 2x18 birds that I built because I had the motor mounts that I got in a big purchase off of Ebay. A 2x18 cluster of A8-3s works nicely with a Big Bertha sized bird at B6-4 Field. I have no particular attraction to them. It was just something different.

It's very simple. Take two A8-x motors and you end up with a thrust profile similar to your beloved B-14. In addition to that, you get the fun of clustering.

A8-x multiplied by 2 as tested:

Total impulse 4.64 n-s
Peak thrust 19.46 n
Burn time 0.73 seconds

The A8-5 cluster becomes a true B19-5. Though it is a little heavier than a B14, it's great for lifting heavy loads safely to lower altitudes than a C11, perfect for a camera rocket on a school playground, small park, or large back yard.

I never thought of it that way. I think two 18mm rockets fit in a BT-55 tube. That would make for some cool upscaled two stagers.

Hey Bill;

Good thread. About the clustering (or pairing) of two 18 mm motors. 2*0.736" results in an ID of 1.472"; that's not going to fit inside a BT-55. But it would in a BT-60 (ID = 1.595").

Good luck!
