Received my Member Guidebook from the NAR. It sat in the letterbox for a couple of days and the snails found it quite easy to digest. I guess that is why it is called "snail mail".
What did you do rocket wise today?

A lot easier to track when they come down. It is fun to fly in the snow.Where about do you fly and what limit of wind speed do you not fly?The Iris is a nice looking rocket.

The Iris seems to be a very stable rocket design, no spin or weathercocking during ascent. Began scratch building a 2.6" version last week - I hope it performs the same way. We are in northern Ontario, Canada. Lots of room to launch in winter, not so much in the summer. Wind speed was a calm 5mph but I would normally fly up to 15 mph. Only downside is recovery has to be quick or you end up with a tube filled with melted snow!

Getting closer to finishing my 7 motor Job....
Got to add nose weight when I get the electronics package into the e-bay.....

Nice work looks mean !
Awesome
I catch myself stopping and considering buying this rocket every time I see it
Looking good
interested to hear what you have to say about this when you launch

(Friday, not today) Got 2 kits, and 2 retainers I ordered on black friday. Kits were in stock when I placed the order but not when it came time to pack and ship them. Vendor kept me updated via email every few weeks until they shipped it out.
<new tab → Google → "LOG magnum"> I see that a stock Magnum it's 3×29 mm. What's the seven motor configuration?

From the LOC site:
Standard Magnum Rocket Kit. 80″ tall, 54mmt with 6x29mmt. 34″ Booster with 24″ payload section. 60″ Parachute, 25′ Tubular Nylon with ends sewn.
https://locprecision.com/product/magnum/
Pick "Magnum" and not "Mangnum 3E" which is a 75mm with av-bay

It has a 54mm in the center, and (6) 29mm's around it. Two of the 29's vent to the top with the center motor, the other four are plugged.
I did have to contact LOC to get this old style version.

Happy to have finished a challenging Bomarc 2.6 scratch build.
Goals: light weight, low cost, G motor capable.
Approx 80 parts. Prime and paint in a few months.
735 grams. 29mm MM
-------------------------------------------------------------
1/4" mahogany veneer underlay plywood, finished thickness 0.168"
Majority of the ply grains are running perpendicular.
The outer veneer is paper thin on this sheet and running parallel.
Used some wood filler and block-sanded to smooth.
Balsa strips over and under wing to build the conduit.
Sand to fit body contour.
54mm decorative ramjet pods. Designed to allow small amount of air through.
Make some balsa nose cones using scraps. Cut circles and stacked/glued them.
After the lower section, motor mount, exhaust baffle and ramjet pods are installed, I set to dry.
Epoxy the wood Fin/conduit system to completed rocket airframe and install motor retainer.
Paint and fly in spring with this theme.
Still needs launch lugs installed.

The IRIS has always been my favorite rocket. You are right about about the IRIS being stable. I have had a few kits over the years all sizes and they always did well. Its the fin design I think .Your 2.6 version should perform very similar if you scale it. I scratch built 4.0 version a while back and waiting for a G80 motor. Yes, up to 15mph is good for drift. When you say a tube filled with snow, does that mean it landed in deep snow? Summer time is not favorable? It must be fun to have all that space. Good luck with your 2.6 Iris. Like to see it fly.
Congrats on this one. This will be a real head turner. You did an excellent job. What is your predicted altitude?

They must be interested to read it. Any damage done to the literature? Snail Mail is correct.
It is still readable, just a bit water and snail damaged.

That looks darn good to me. Did you use the same instructions from Estes? This is a nice rocket to fly. I had one once. I cant remember if it was 18mm or 24mm. What mount did you do? Where did the parts come from?

I have a pic of my 4.0 , 29mm , 68 inch Iris Scratch built. Next to it is an Estes Iris 18mm.

While not an actual kit, I've been working on a Semroc Texas Firefly that I put together via a parts order wit eRockets. This is a very satisfying upscale of the Centuri Firefly, which I'm also working on. The Texas version is nice and solid and one can imagine it being a great cornfield flyer. Yesterday I finished sanding. Today I hope to get the launch lug attached and prime it. Next launch window is February 13, so no need to rush.

I hope I'm saying "that's the most dark matter motors I've ever seen go at the same time"
Realistically, I think I am bout 2-3 months from launch. I'd like to fly an I-280 and a pair of H115DM's for a test shot.
Not today, but a couple days ago I ordered the various important parts I still needed for my next build, a Wildman 5" Gizmo.
Should be a fun little build but I think between the Gizmo and my previous Mega Magg, the stubby rocket urge has been satiated for a while.

How do you fly a highway on any motor?
(Many years ago, it once took me 4 hours to get from Fairfield to Hoboken due to an epic traffic jam on I-280.)

If u think of it or have someone else video the launch be great to see
Good luck !!
I grew up right in the center of that map.

Thanks. I grabbed the OR file for the original design from K'Tesh's plan thread and then made a few mods. I upped the motor mount to a 24mm, extended it to 3.75" and replaced the motor hook with a retainer. Also replaced the plastic nose cone with a balsa cone. I'm partial to balsa cones as I can add or remove weights (washers) easily in the field if the stability caliber becomes an issue with a given motor. The parts are just standard bulk build parts from either BMS or eRockets.

Very nice. I haven't built one in a long time. Is it an 18 or 24mm?

Pretty epic amount of painting to do at this point once it warms up.
