Anyone ever use the Estes PSII Booster?

What I want to know is, with the 29mm motor retention system that comes with the PSII rockets, how does the booster attach? Does it fit up inside the threaded retention system, or do you simply tape it on?

Thanks.

Yes, I've used it quite a bit.

The booster has a coupler at the top of it. You simply slide the booster into the bottom of which ever PSII E2X model you have and your done. No tapping of motors or the stages is needed. So after prepping the recovery system in the upper stage you would unscrew the motor retainer, slide in your 29mm BP motor and screw the retainer back in place. For the booster you unscrew the motor retainer, insert the 29mm BP booster motor, screw the retainer back on then slide the couple that's at the top of the booster into the bottom of the upper stage and your ready to launch.
