I did a test over friday/saturday using bob smith foam cure, simlar to foam-tac brand, it's a clear glue used for bonding foam that can be used as fillets or contact cement where you apply to both sides let dry then adhere, or just as a normal adhesive, it stays flexible. In any case, my polycarbonate fin test piece adhered really well to my test slot I made, so today I glued the fins in place and put clear fillets on them. Hope to re-fly it in two weeks.

Flight today at tri cities Washington was perfect, dead straight, perfect deployment and no damage, had 10mph winds too, very stable, weather was very sunny, great way to end the flying season.

Frank that flight today might have been the best yet I have seen for that rocket, it didn't even wiggle under boost.

Yup, and the altitude was about 100' higher than with the lower mass fins, so simulation matched pretty well. I love how these big foam rockets just hang for about 3-4 seconds at apogee before popping the chute, especially in a headwind.

My 8" diameter 6' tall Pershing 1A flight to 1100' from this weekend at tri cities, WA, courtesy of Derek McGuckin. Chute took a while to come out of the deployment bag but no damage to the model. Video thanks to Derek McGuckin.

Better than “open on impact!” Good thing it was built light to start with.

Nice to have a beautiful scale rocket that is tough enough to fly regularly. Of course, no matter how close to scale you built it, that’s one major difference between yours and the real thing: the REAL missile was a single-use edition.;)
