Yes, Vito - let me know what you think of Mike's remedy there.
HED - Head End Deployment - simple form is coupler with switch-band in
middle. Shearpins
below nosecone shoulder, above booster (drogue section)
It's basically what you're already doing :-)

The kit is a great starting platform for a strong rocket. You need to
think to make it better as any other project.
There are several things to address on how to build it for maximum
performance.
The biggest problem to resolve is the metal nose piece.
The thin washer and flat base of the nose piece makes a serious problem.
Especially if your gonna spank this baby with a kick ass motor. Far more
serious than fin failure.
Just drop your nose cone on the floor and see what happens. It will come
completely lose.
I’m dealing with that now.
I’m happy with the kit as a super strong platform to build on.
Just seriously, would you guys with the abbreviations (such as HED) please
spell it out first so I know what the heck you are talking about.
Thanks

So the ARRD I have used before, I also used the breakwire thing jimmy
turned me onto - don't remember what it is called, in my garage.
I'm thinking 20' of kevlar, and this mylar streamer all wrapped up in a
Nomex...https://www.homedepot.com/p/Bird-B-Gone-Holographic-
Flash-Tape-Bird-Deterrent-150-ft-x-2-in-MMAFT-SIL/206044654
Imagine that thing re-entering from 5-10K :-)
Anyhow, cheap and easy fast up and down.
You know we have a points system for this race :-)

Yes, reliability is my biggest concern using a tether device. My thought
is to use multi-strand wire from the ebay to the tether device taped to the
shock cord, and then solder and heat shrink the e-match leads to the
multi-strand wire where they will not flex. I plan on using a deployment
bag to minimize flapping – but it is still going to flap no matter what.
I also looked at the Jolley Logic Chute Release, as it is all
self-contained. But it looks a little small for this application. It uses
a rubber bands to wrap the chute, and does not look like it would work in a
configuration where a drogue is deployed first, which then pulls the
deployment bag off when the tether is released to deploy the main.
Anyone with experience with this vs a traditional tether device?

Hi Tom,
I have something that came from Defy Gravity. I don't remember what it
was called. It uses an e-match to separate two haves that hold cable loops.
My concern is that this piece of machined aluminum and my parachute are
flapping in the breeze with an attached piece of e-match wire. I've had it
break before. Even if you tape it up to the shock cord with stain reliefs,
that solid core wire can break from excessive flexures.
How do you keep it together and reliable?
Thanks!
Steve

I am plan on deploying both the drogue and main out of the main body,
using a Tender Descender (never used one before) to release the main. The
method Mike Stoop describes sounds very interesting – one of those “I never
would have thought of doing it that way” – but I like to reserve the
nosecone space for my Beeline GPS and other flight tracking electronics.
Using the main body for both main and drogue, I can definitely fit a 54mm
K550, and maybe even a K700 – or maybe not. I am using an Aero Pack 54mm-3”
conical motor retainer, so that moves the motor a little aft, and I plan on
shortening the eBay tube from 7” to 5 or 6”, which will give a little more
space for motor and chutes.

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.
Steve

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. :-)

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 :-)

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.
