Thanks. It's a scratch build. I borrowed the fin design from the Mach1 65mm plan and went from there. I wanted something fairly simple as this was my 1st experience with rail buttons, ttw fins, and epoxy fillets not to mention my 1st mpr build. So far, no major snags....fingers crossed.
Kinda what I've been thinking. 18mm tubes. Even with an A and two 1/2As it'll go damn high.
How about 13 mm adapters and ¼As?
Oh heck yeah. The seams between the two pieces of fin plate you'd be a fool to deal with with the fin in the way.
Nothing. It was a serious slog to get to that point. Probably 8 hours of work. The remaining 90 parameters are going to take much greater divining of the values than most of what has already been dealt with, and they are the more critical values that the control systems depend on for a successful flight.
I meant to say in my earlier reply, please get someome in your club to record the presentation, and please post it.
No pressure eh
. Let me see what we can do.

Smart idea to test with this nice sounding design. What size motor do you plan to use on its maiden flight?
Final primer coat went on the Vexillum. I'll probably do the wet sand on Tuesday. I was a little sloppy with the epoxy on the front end of the fins, so this will most likely be a 3 to 5 rocket (looks reasonably presentable from 3 to 5 feet away.
I like the fin arrangement. Very nice.

Wow! These fins are not coming off at all. What is the rockets length?
It fly's very well on single stage or using the booster with it. A nice performer. You will love it. It was my first 2 stage rocket. Thanks for the nice comment on my upscale Arcon Hi.
Awesome John. Have you ever used West systems black dye? This rocket will put on a nice show.
This is my first time using the dye. All my other HP rockets are painted, but this one will not be, so I'm probably better off in the looks department by having black epoxy than the default yellow.
It has to be over 200 acres of crop fields. The group launches 2 times in the spring and 2 times in the fall.
It's just surface mounting and glue.
Had to look up Luton Town.
no, but a close friend is. Luton is his home town and I’ve become rather fond of them. The local hardware store had a pretty poor selection colors, so this is what I came up with
. So I am sure there is no flight data but will look.
Leaning towards a F23fj-7. Sims a little over 1400ft so visibility and recovery should be decent.
Thanks for the info on your rocket. Arcas is a nice looking rocket. Are you going to paint it to the scale paint scheme? I have an Aerotech model from years ago and it is a great flyer. No, I never did a Build thread on Arcon Hi or my scratch built up scale. I wish I did. I see they are all out of stock of them. It is a fun kit to build and a cool looking rocket. You should hold on to it and build it. Its a good one for any collection.
That should be a good show on an F23 FJ. I have a couple of those Im itching to launch in my Aerotech Arcas. What is your rockets weight?
I watched the video on YT. Nice time lapse video. Nice launch too! Was it a cluster flight? I noticed how your drink in the glass got smaller and smaller.
Great job on the build.
All nice shots.I am just taking baby steps with Ex motors. I mixed up rocket candy and poured some 24mm grains using spent 24/40 casting tubes, nozzle, o rings etc.

I am grateful the motor produced enough thrust to clear the rod at a decent velocity, but mam was it a slow flight. I saw it slow and nose over at 100' shortly after burn out. It was a 1.8s burn, was looking for a E30 but it was not anything close to that.

I had a 808 cam and Raven 3 in the payload section. I will look for video, but it was so slow and low the Raven never armed after launch
