Mini M&M Rocket - AslansMonkey

简介

While joking with my son that I need to stop buying Pringles because I keep making rockets out of the tubes, he held up a package of mini M&Ms we'd just bought for my grandson and said "I bet you'd make a rocket out of this!" So I did. And here it is. Build instructions: There are two different versions of the fin unit. 1) Uses a BT-5 (13mm) motor tube. You'll need a motor block if you build that one. It's slightly lighter than the all plastic one, but more hassle. It works though. I built one this way. I believe the weight difference is negligible but this one may hold up better long term than the all plastic one. 2) An all plastic one sized for Estes 13mm motors. Held up fine for the one launch I've done so far, time will tell if it lasts for long. Build Notes: * I use 250lb kevlar string as a shock cord. It's fire proof...enough. * I also use a small square of nomex cloth instead of wadding. These are both visible in the photo. * Use a streamer for recovery, it's a light rocket. * Drill a hole in the cap and run the shock cord through it, knotting it above the cap and gluing it in place. Then cut off the hinge. I didn't do this at first and 3 of the five rockets lost their cap at apogee when it got blown off the rocket. That hinge is NOT strong enough. * I had to glue 3 10-24 hex nuts to the lid for weight. They came off on the initial launch, you can kind of tell as it reaches max height in the video. Be sure to sand the lid before…
