Good point, Gary. I assumed it was in the 6-10 lb. range and based my recommendation on what I've flown successfully in that range. But someone else mentioned theirs weighed in at 15lbs. Seems a bit heavy, but nonetheless, it is what it is. So be sure to check the motor specs carefully against what your rocket weighs and choose accordingly...
Depends on the modifications and ammount of epoxy, etc - my original, no electronics, stock from the box Magnum weighed in at something like 8 lbs dry. 10-12 on the pad, depending on motors.
my dual deploy model with extra bulkheads, chutes, etc comes in 18 ish loaded ( never have weighed it dry, hmmm ) .
the stock kit is not that heavy and should not weigh much over similar height 4" birds.
I cringe when I hear about 4" x 84" rockets weighing in 10-12 lbs, when they should be in the 4-5 lb range.
Been doing this a looong time and no need to overbuild that much unless you're seriously going mach 1.5 or hitting them with huge motors, etc.
carry on, decide if you want dual deploy ( easier to add now then retrofit ) , build it up, then weigh the bird for motor choice.
