Default Booster idea?

Can I epoxy/JB Weld two or more Estes E12-0 boosters end to end, cap off the front booster, thereby having a longer run time? Planed use is in a scale model of a 50's fighter that used turbo jet and a rocket for power. I guess that the question really is can one booster fire through another case that has already fired.

Absolutely. In my Ghetto rigging days, I did that once and it worked fine. I taped mine together, however, LOL!

Or buy a reloadable 29mm or 32mm RCRG motor and use longer burning reloads. While tandem staging works to a degree, are you willing to risk the time and money invested in the model for a pair of glued together black powder motors?

OK, so who/where is "RCRG" motor. I've never heard of them and haven't seen them in my local hobby shop. Please give me a web address so that I can investigate. Thanks!

RCRG = radio control rocket glider, and Aerotech makes 24mm and 32mm long burning reloadable composite propellant motors for them.
