I fixed the image file. Seems like I need to find a new place to put my pictures.
Thank you!
This build is going to be equally as interesting to me. I've made up several of the build techniques I'm going to use on this, none have been tested. The only way I'll know if they work is to put them on the rocket.
The biggest challenges of this is going to be the removable fins and the 4.5" tube. Looking at the rocket once it's done, you will never be able to tell that the fins are removable. All of the screws and separation points will be hidden under scale details. As for the 4.5" tube, I'll use 2-part foam to build up the surface from a standard 4" tube. Hopefully, this will give me a scale-like finish for the fuel tank as well.
Right now, however, I am working on masters for the transition molds. The transitions I have right now are made of balsa right now. Through some miracle process, they will eventually be hollow fiberglass. The process of making the molds will most likely take a very long time, so this thread will go very slow for a while. I will post pictures as I go.
you can buy 4.5" tubing. Talk to Wildman or Liberty Launch systems. PR made some and they should be able to get it. If not I have 5 x 4.5" couplers that you can join with 4" BT and make a fiberglass BT out of the manual way.
That is what I was going to do for a 1/4th scale Terrier Nike (and might still)

Since you Are a high power flyer (and not to be a sterotype here) why not invest some cash into gismos that move the motor like in the real Aries rocket?

well at Narcon 48 a man had a computer gismo that had a self stabilizing computer, it would correct the angle of thrust for whatever shift there was in the rockets movement
what section should i put that in?are you talking about gyros? this is a topic for another thread. (im sure one will pop up in a few mins )

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ we're talking about thousands of dollars. A L3 project would cost less.
Plus, making that system in extreme miniature will be very, very, very,very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very, very difficult.
Bsmith, one thing you could try is to just put the buttons on the aft of the rocket and use a standoff on the rail. Because having the buttons at the top you wont have as much stability, if you put them at the bottom and use a standoff on the rail to keep it from hitting the fatter upper section you may get more time utilizing the buttons. Im not sure of the rockets measurements so im not sure which would be better.

That is by far the easiest option, but both my dad and me agree that it would look far better without the 2" standoffs on the lower section. I'm also not sure if 2" standoffs can support the torque of such a large rocket.
Hmm.. good idea
and the standoff would just fall away once it leaves the rail? There would probably be a danger of the standoff taking out the gimbal shroud though. I'll look into it.
One thing I probably want to avoid is putting any rail button below the leading edge of the fin, because that entire section of tubing will be completely removable and held in place by very tiny screws and about a 1/2" section of coupler on the top.
The rocket will be made with Blue Tube, but that section will still be iffy structure-wise.
here is a crazy idea, how about fly-away rail guides?
Thanks for being blunt
I didnt mean those i meant....... One sec for the linkhttps://www.apogeerockets.com/educati...sletter243.pdf
The entire 3" section is 35" long before it transitions. I don't have a final fin layout yet, but the removable section will most likely be 8-10" long. Once the length of the section is taken out, the MMT only has about 6" of tubing that it will glue into. It will be completely fine, with more than enough strength to take even a K, but there will only be enough room to put one button. After that, the other button will most likely be in the drouge bay.
Yeah, what your describing makes sense, but I don't think what I described makes sense to you.
The blast deflector for the pad I'm talking about would be 3 feet below where the rail starts. Because of this, when the rocket sits on an 8 foot rail, the buttons will still travel 8 feet on the rail. If the rocket sat on a normal pad, the buttons would only travel 5 of the 8 feet.
I think this might be what your talking about in "effectiveness." The buttons can be as far foward as you want them to be, you just have to have a rail long enough to let the rocket come up to speed. The pad design I have will just set the rocket down further on the rail, giving it enough room to gain enough speed.
