Just checked my ASP kit (Estes #0862)..................1/16" die cut balsa.

But, that's a thought if someone was willing to try it -- a laser-cut set of matteboard fins, 0.02" thick. Carl's material is far superior to what Estes used in the past, so it might hold up longer once it's been sealed and painted.
I heartily agree! Structurally, the long-chord, short-span, right-triangular A.S.P. fin is probably the strongest possible fin planform for use with *any* kind of fin material, so such "fibre" fins should hold up very well. If Carl brings out an A.S.P. kit (either Deci-Scale or a reproduction of the BT-20 size Estes A.S.P.), I would have absolutely no objections to fibre fins in the kit.

Thank you, Joe! Up to now I was 99% certain of this, but it's always best to have definite confirmation.

Carl, there you have it -- straight from the horse's mouth!

Sorry, 'shire, couldn't resist...

You've nothing to apologize for--I am pleased to (rhetorically speaking) be ridden thusly!

Ah--thank you for posting all of those! I'd never seen that...cardstock? red-and-black "roulette round" ASP (I've seen that round, but not that cardstock model). Being made for 13 mm motors, I presume the rolled body tube is BT-5 size (I used to have a mold master for a BT-5 size 5:1 tangent ogive, from which I cast solid polyurethane resin [with "investment cast" screw eyes] nose cones, for my Nova Hobbies ASP kit http://www.rocketreviews.com/nova-h...-mike-goss.html [I never sold kits with those, because I had so many balsa 5:1 ogive nose cones]). Today, one of the 3D printing folks could make such 5:1 BT-5 ogives. Also:

Those "super-caliber cone" ASP rounds look like the pictures in Dr. Richard Morrow's book, "Small Sounding Rockets" (which--the last I'd heard--he was working on reprinting, perhaps via POD [Print On Demand] publishing [here http://www.google.com/search?ei=9UK...0.VEJK4p7 cMxM is his book]). He also covered a two-stage sounding rocket that used that mushroom cloud sample-collecting nose cone, called the ASCAMP (see: http://www.google.com/search?source...160.Xuu7eh_FuMw ), and:

The ASCAMP used the delta-finned ASP as its first stage. The SCAMP second stage, which had Aerobee 350-like fins (although much smaller) and the "super-caliber cone," used the same "Baby Sergeant" rocket motor as that used for the Jupiter-C/Juno I and Juno II high-speed solid propellant upper stages.

You are entirely welcome . . . I believe that data should be shared, not hoarded.

A little more "FUN", from the same source . . .
