Hello all, I've lurked here for a while, but decided I needed some input before a build...
I did lots of LPR as a youngster, and I am now getting back into this great hobby as my kids are getting bigger. My brother knows this and gave me a Priority Mail shipping tube thinking I could built a rocket out of it... hence the name Priority Mail.
Any of you who have handled these tubes know that they are fairly stout, maybe even too heavy. The tube I have is about 30" long, 2" diameter, and I'd estimate the wall thickness at over 1/16". My plan was to build this for 24/29mm and try to keep the budget as close to 0 as possible; hand made nose cone, motor mount, bulkhead(s), recovery, etc. I've never done MPR before, so I have/will be trolling these pages for info. My goal is not altitude or speed, just a very durable rocket that can be launched over and over, and be built on the cheap.
Now onto my ?'s:
I have some 1/4" pine stock laying around, and I was thinking about using this for some very stout fins. Any downsides to this? Weight is the first one I can think of...
I have not yet played with any Sim programs, so I'm wondering if my motor choices are right. I have lots of experience with Estes BP motors, and I have plenty of E9-4's laying around. My plan is to build this for 29mm and then adapt it down to 24mm for the first few flights.
Thanks in advance for any input...
Brian
