Well, I looked back at my "level one development" and i asked myself "WHAT THE HECK WAS I THINKING?" an I1299N for a level one? a 12" parasheet? 3/32 ply at mach 1.8? Well first of all, right off the bat i would like to apologize for doubting any of you. It's time to find a More practical way to do HPR ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Ok, Well this is actually a clone build, But i figured it would get more attention if i left out the "Clone" Part
Ok so For those of you who dont know, USR was a Rocket manufacturer from 1979-2005, at its peak it had a full line of Motors and kits. They were Interesting, to say the least.
Ok the backstory is over, and here are some problems i have run into with the cloneing:
1: The 3.16" body tube, i have 2 sub-options:
a. I can roll my own tube, using a BT300 as a mandrel, maybe with something wraped around it
b. I can use a 4" tube and just use centering rings instead of the original "MMTs as the lower body tube"
So if anyone can find a 3.16" BT let me know please.
2: the 12 C6 engines that this kit was originally based around.
The C6 Contains 10.8 grams of propellent, and 12 of those would make it a HPR rocket. SO that limits my motor choices to the A8, A6, B6,B4, the D21 and D24T (12 motor cases FYI)
So those are the only problems i could see.
As far as the dimensions go, i will take the picture off the USR site and use the 3.16" as the BT diameter and go from there.
I have almost no other data on this so any help would be greatly appreciated. Oh and the USR page about the Swarm C6-7 Is here at https://v-serv.com/usr/kits/swarmc67.htm Here is one thing that i wanna point out upfront, the kit doesn't weight 0 grams as the page says! :roll:
Thanks,
SD
