18", on OR I made the fin can as a separate body tube made of plastic. Total rocket weight is 78g w/o motor.
 
This one weighs in at 3.5 oz. without motor, 5.2 oz. with a D12-7. OR sims say 920 ft. Never flown an altimeter in it, but the Mk.1 eyeball says that is pretty close.

Did you get a coupler to fit in the cardboard section of the stock can? I couldn't get one to fit, so I peeled off the estes cardboard and it slides into the BT-55 tube nicely. Did you dod anything to the cone that would normally be for igniting the next stage? Is there a payload bay on yours?

Nice looking BTW.

On mine I made the hole of the cone a bit bigger with my dremel.

I was thinking the same for the single stage. I found that couplers do indeed fit (though tight) so I am going to make sister rockets. One single stage with the can and one two stage with an 'E' motor mount as I have some E-9-6's in need of a job. I think I will try to use one NC with a cargo bay and share it between the rockets to hold the JL Altimeter3.

Since I'm building 3 of these rockets with the booster 55 I decided to put my Dremel to work on one. I carefully removed the forward portion of the fin can to allow the use of the longer 24mm E 9/12 motors. I made a motor block that I coated in JB weld to give it some heat resistance.

You are my hero, I looked at that and decided it wasn't worth it. I am working on one that starts with a D12 in a booster 55, I added a coupler but it mates to a traditional BT55 rocket with a D/E mount. I plan to run the D-12 to an E9-6 and see what happens, Rocksim says ~2500ft.

I had couplers in the spares box that fit just fine so I've used those. Someone else here on the forums (I apologize for not remembering who it was) suggested peeling the short piece of tube off and going directly into the BT-55, but I haven't tried it that way yet.

I didn't do anything to the cone at all, but I did wonder if I should! So far so good, but I am a bit concerned that it could cause a problem if you get one of those Estes D "12 gauge" ejection charges...

This is another one of my "booster builds". I had a bunch of transitions rolling around in the spare parts bin... :p

Anyone out there willing to provide the ID specs of these boosters? I would like to use them as fin cans so need to know what size tube will fit.
Thanks

Typically one just uses a length of Estes coupler and the appropriate body tube, e.g. for the bt55 can use a bt55 coupler and a length of bt55.

Note that the PSII E2X booster is a weird size that's hard to source IIRC.
