Where is that kit from? I like it. Motor mount size?Got the BT-50 Black Brant ready for primer/paint...

Not Wally but the kit came from Mach1rocketry.com .Where is that kit from? I like it. Motor mount size?
As o1d_dude said, it's from Mach 1. This has an 18mm motor mount. I added the motor retainer. They have several fiberglass LPR kits, BT-20 through BT-60, plus mid and HPR up to 4 inches. Very nice quality.Where is that kit from? I like it. Motor mount size?
Gave my scratch built Standard Missile a final paint coat. Just waiting on the decal pack to arrive to finish it off.
Finished painting and de-masking of my semi-scale 260 Space Booster. Now I can install the railbuttons.

I finally ordered one of those, that looks great!Finishing up the Flis ACME Spitfire. I wanted it to resemble the Far Side panel so I used Monokote aluminum trim for the body and red on the nose. The fins should be Monokote blue to match the 'toon but I liked the look of metal panels and used laser printed label stock instead; the original art came from the Flis website. I still need to do some detail, mostly the seams need some work. The rivet lines could be better, but for a first effort with a new-to-me method of finishing it came out OK.

Looking at the instructions, it seems the main chute does go between the centering rings, but not wrapped around the pod like the pod chute. Regardless, cool kit.Resurrected a long stalled build I started months ago.
The Estes Design of the Month Kamikaze Baka.
https://www.spacemodeling.org/jimz/eirp_70.htmGot hung up on the clear canopy and the rear ejection design.
Clear dope is not an effective glue for the clear plastic seams. Too weak.
Replaced the canopy with heavy cardstock instead. With glue tabs.
And the design is for dual chute rear ejection with a pop pod.
First, don't see a thrust ring or coupler to prevent the pod from travelling all the way to the nose of the airframe during thrust.
Second, while the smaller chute is wrapped around the pod tube between the centering rings (that's fine) the main chute is ahead of the pod. How does it get ejected from the tube? Seems like the ejection charge will be pushing the main chute into instead of out of the airframe.
So I switched it to traditional single chute nose blow design. KISS.
Which makes the tail fins vulnerable to damage at landing.
I'll take the tradeoff.
Better to have the chute deploy at the nose end than not deploy at all.

You're right! Now I'd be concerned about the pod sliding out with two notches for the main chute shroud lines. Seems like that would jam if it doesn't slide out straight.Looking at the instructions, it seems the main chute does go between the centering rings, but not wrapped around the pod like the pod chute. Regardless, cool kit.
Thank you! The nozzle is two cardstock transitions around a 38mm motor mount tube. Those two transitions, the nose cone, and the central transition all were homemade, along with a number of bulkheads and centering rings. The three transitions were made from five layers of cardstock soaked in epoxy. There's a centering ring at the aft end of the nozzle, and the space between is filled with expanding foam.That's real clean! Is the nozzle for show is there a long skinny motor hiding in there?
I've been building and repairing since Monday. I was at a little launch yesterday. I was trying out spooler pods which where pretty successful even with a couple of over stuffed A10-3Ts blowing through. I almost lost a Silver Hawk that I had since '98-9 (one of the original prototypes), but found it in the middle of the road on the way out. I'm having more of my bad luck and Pauli Effect with mini-cams today. I'm starting a thread about that.
Glad you found it Doug; wish you were still selling kits. I particularly liked the Silver Hawk.
My L3 project was the same thing except the tubes were 7.5" and 6
Yep. Party streamers from reputable companies make for great wadding. That's all I use.Should work! I use dollar tree party streamer when using wadding. Fire retardant treated and biodegradable.
I bought some from Amazon but it was horribly combustible so returned it. Gonna visit the Party Store next...Yep. Party streamers from reputable companies make for great wadding. That's all I use.
It's called weather cocking, named after rooster-themed weathervanes.Better launching success than last time. With the engine adapters, the rockets seem to go perpendicular to the wind, then with the wind on parachute. What's the science of that?
Model airplane guys use a glue called " Formula 560 Canopy Glue " ( Pacer pt -56 ) might want to check it out.Resurrected a long stalled build I started months ago.

The Trivecta 318 was a 'rocket of the day' yesterday so I went ahead and ordered one at 20% off... I already have the Trivecta 329 waiting to be built...I went outside to paint this morning, but it was raining. Instead I ended up ordering a few things.
I have a Mach 1 Trivecta 318 coming and an Estes Sterling Silver coming. I haven't build a cluster or staged rockets before, so I figured I might as well start small.
I also added a few bits to make a Mach 1 BT55 Electron into a near MD 29MM build and an Estes Crossfire ISX just because.
