I'm going to be building an Estes Goblin for dry-lake launches with AT 24/40, maybe 24/60 power. Probably F35 or F39 as the highest average impulse, as I'm more interested in altitude than speed with this model. Will have an Eggfinder Mini in the nose. I want durability on the hard desert. Have already decided to go with 1/16 bass and TTW construction for the fins. Thinking about papering them.
Also leaning toward a hot-wire chute release run off a Quark for motor-eject dual deploy with a 15-in Estes chute. Which should get it slowed down enough that just painting the basswood and TTW with good fillets might be more than good.
I have a Harbor Freight vacuum pump. Thinking maybe BSI 30-minute epoxy thinned with isopropyl alcohol and some nice smooth bond office paper bagged would give me the smoothest finish with greatest strength.
Is this massive overkill? Any recommendations or pointers? I've done a little searching, but found limited results on bagging fins for papering them.
Monokote is also an option, and would probably be lighter and easier. Would just have to paint the yellow ones, as I only have red, black and white. I guess white MK under yellow paint and black MK for black would probably give best cosmetic results. Do the Estes water transfer decals stick to Monokote?
Should I invest in the BMS foil-lined MMT for the AT cases? (Guess I should pick up some centering rings to go with the OD greater than Estes BT-50, too...)
Any other thoughts?
