I was wondering if some one could give me a dezine for easy fall away boosters. Also easy robinson coupling plans, and also will liquid nails work for splicing?

Liquid Nails is a no. Are you able to get a polyurethane glue like pl premium?

Getting ready to launch this airstart/staging mecahism today if plans go well. The lower stage has a glueless pvc (no metal) version of the robinson coupling on board as well. I'll let you know how it goes.

Will pl 750 work? Or does it have to be premium? Can some one also tell me how to attach bottles end to end

PL Premium 3x or 8x is well tested and what I know will work. Anything else, you will be experimenting.

Check out the How to section of this forum yet? Some good stuff there.

Great! Best cure time for the plp is at least 4 days. But then the bottle should fail first.

Wow my phone must have mangled my post. Is the pl roofing black? I'll be very interested to hear your results.

Its black, it didn't burst at 80 psi, but the pvc launcher did lol

Oh um, you're supposed to use Schedule 40 at a minimum... best solution is to use steel for lower and screw on pvc launch tube. But pvc sched 40 works if you keep it under 200psi
