Looking forward to the return of the Super Big!
I'm a bit perplexed by all the comments about beefing it up. Yes the BT-80 tubes are thin wall, and yes the stocker Super Big Bertha and Broadsword had 1/8" fins. I've had both, gave away the SBB after many years and many flights, and still have the Broadsword....built is many moons ago as a kid. After an infamous Estes E15 cato, the Broadsword was cobbled back together. Since the cato, it flies almost exclusively on Ellis G37's and Aerotech G55's...fun flights. No reinforcement, not built well, been through 2 catos now (an Estes E12 too:cyclops
and still going strong (but ugly!).
Not saying y'all are wrong...I'm not! Only sharing personal experience with both....really one and the same except for the longer motor mount. My experience is that the stock SBB or BS don't need reinforcement for any 24mm motors. I do not treat them gently; once a rocket does something silly like cato or core sample, it immediately becomes an abuse hound that I try to lose/punish.
Now you wanna put an I200 in there, and you may want to reinforce slightly: maybe. However, I'd hedge a bet that I could fly the SBB new kit on an I200 (ok, I205 for disposability sake) without a touch of glass and without any additional balsa. Those thin wall tubes can handle more than people give them credit for!
