This is one of my cheap HL booster 55s. Its done up to look like some sort of sounding rocket...

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

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.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

Note that the PSII E2X booster is a weird size that's hard to source IIRC.
Note that the PSII E2X booster is NOT like the 2256 or 2257 . . .
