Is it really required? Certainly not. But I have a history of hard landings
and broken fins, so this is what I do. Like I said, I have the material, why
not use it? I could just use glass, but the carbon looks great, and because
of the decal, I’ll have to put a good clear coat on it anyway. It will look
even better. I bag most of my rockets. Have been for years, so it’s kind of
how I build anything bigger than 38mm, and sometimes even then. For small
stuff I still use glass, but I just do it by hand. ;-)

Carbon lay-up will look cool - but is it really necessary for J and K motors?
wont break mach 2 unless you put a good sized L on there...

Great discussion guys. The crap you see on Curtis' fin stock is actually 3M
Industrial grade Rubber cement. If you think about the operation, you're
gonna stack 3 sheets of G10
and cut them out, a rocket kit at a time. You really want that stuff to be
strong since any slippage means you have a fin out of wack.
Acetone, lots of it, you bath it in that and use T-Shirt towel material like
you find at ACE.
Scott ripped the tabs off of the fins, I ran a 1/16" bevel to round them all
over. Lookin killer - and no rubber glue :-)

Cool. Good input. I recently acquired an older RDAS compact and was thinking
of using it. While rather large by today's standards, they are still
excellent units. I also have an old pyro based 'chute release, but I've never
really liked it. It let me down several times. So I figured I'd just use
shear pins and pack it in the nose. Sounds like that works well.
While I have no plans to try and wreck it on a 54mm K motor, a full J will
still stress it, so I'm doing a carbon fiber lay up. I've got the material
and a vacuum pump. I did the same to my Blue Iguana, and it came out great.
If course those were surface mounted fins, but still: why skimp?
Thanks a lot,
Steve

I've used just acetone on Madcow's fins, it takes a good bit of elbow grease
but I've gotten them to come clean without any other chemicals, and no
residue afterwards.
I've built a very similar Madcow/Rocketry Warehouse kit twice now, the Osprey
75 (OOP), which was another 3" head-end deploy (HED) rocket, airframe is
about a half-inch shorter and the fins quite a bit longer. I've always flown
it DD. I use a 36" TFR chute in the nose, wrapped in a nomex blanket with
~18' of 3/16" tubular kevlar, it all fits (the chute *might* be thin-mil, I
forget). I replaced the screw that holds the NC tip in with a 1/4" forged
eyebolt (OSH sells these) cut to the right length. Originally I used an
Eggtimer TRS to do both GPS and deployment in the avbay, after crashing the
first one I built the second one as a sustainer and fly it 2-stage now, I use
an RRC3 and an RTx now, to get GPS + DD + airstart. For the booster I use a
Chute Release since it only separates at the ISC.
I'm considering building my Avalanche as a sustainer as well, should be able
to leverage everything I did for the Osprey 75 since the kits are so similar.

I used some (previously used) lacquer thinner, which contains acetone. But it
was a later choice. Perhaps the oils I used (mineral spirits, WD-40)
inhibited it somewhat. I ultimately used a card scraper and that WD-40. It
worked. But as mentioned, I had to further scrub the crap out of them to get
all THAT off.
In the end, they look great, but as also mentioned, I intend to do a carbon
fiber lay up, so they're getting totally scuffed up anyway before I do that.
BTW, it was pretty hard to get that stack of fins apart initially. No match
for my 1" chisel, but still. But I guess they need to keep them together to
rout them out. (I assume they use a CNC router to cut them out.)
The rest of the kit is fine. I did have to open the fin slots just a bit
(much too tight) but that's typical.
I do have a question for the list: if attempting to do dual deployment, is
anyone attempting to pack the main in the nose cone? Or are you planning to
use something like a jolly logic chute release and pop it all out at the top?
There looks to be enough room in the N/C for a main, but it will be a fairly
tight fit. Plus, I'll need to replace the screw holding the tip on the N/C
with an eye-bolt.
Just wondering if you were expecting to simply chase it down or try to bring
it down dual.
Thanks.

Acetone does a clean fairly quick removal after it softens.

I see you haven't yet gotten the gunk (tape residue?) off your fins.
It took me over an hour to clean it all off. I tried a bunch of things to try
to clean it off including Goo-Gone, IPA, Mineral spirits and lacquer thinner.
The only thing I found that even kind of cut it was WD-40. Still had to use
some Scottch Bright to get some of it off. Of course then I had to scrub them
all with Dawn and rinse them in IPA.
But they look pretty and clean now. Too bad I'm going to scuff then up, put a
couple layers of CF over them, and stuff them in a vacuum bag. But hey, no
lumps. :-)

Here is a photo with motor tube installed. The fins need to be ground down to
fit into slots. Having a grinder with a flappy type grinding disk sure helped
in getting it to fit the slots. It got dark so I could not take a photo of
the fins installed. I only got 9 out of 12 fillets epoxied inside the body to
motor tube/fins today. Larry Taylor

Yeah, I wish. Too short a burn. My Little dog is almost the same rocket and
it barely touchs 3400' AGL with that load :(
Thats a painted finish (2K urethane). At least, it was :-)

Hey James,
I think that you forgot a "0" after the "3". I think the K2045 has a little
more oomph than 3K in a 6 pound rocket. Lol

Here's the RASAero and Rocksim files.
It's about a 6lb rocket loaded with a K2045 and will do about 3K.
CP is optimal at 30" from the nose. It will need about 4 oz of mass up front;
I plan to put electronics (MARSA) and some Lipos up there.
I'm thinking 40' mylar streamer drogue.
