All four fins are bonded and, so far, the fin can assembly weighs in at a ridiculously light 2lbs and 13oz. Even with the giant fillets, I'm anticipating we'll be under 4lbs before the NC, electronics, and recovery gear.

The sim weight has been set at 36lbs, assuming 8lbs for the rocket itself and the 28lb motor. We might just beat that in the real world. Should sim a hair higher in that case!

Current sim with fairly conservative settings shows around 48,000 with the aerotech tailcone closure that doesn't yet exist. There is ONE and, fortunately for me, Karl from AT said I'm welcome to borrow it for BALLS.

What epoxy are you using for this one? JB Weld for everything?
