For the past couple of months, I have been making spool rockets using CDs & BT-5, BT-20, & BT-50 tubing that fly on 13mm, 18mm, & 24mm motors, respectively. (See this thread for more information.) I am looking to upscale my design for use with 29mm & possibly even 38mm motors. My problem is this: A standard CD quite likely cannot handle the forces from the thrust of these larger motors. I need something with a larger diameter (greater surface area) but still has similar rigid yet flexible characteristics of a standard CD-ROM.
Someone from my club suggested using laserdiscs. IIRC, laserdiscs are the same size as standard LP vinyl records but what I can't remember is how thick and/or flexible they are. Does anyone have one of these (seemingly) ancient pieces of technology handy & that wouldn't mind assessing their potential use for my purpose?
eBay has proved to be a fairly abundant source for relatively inexpensive laserdisc movies but I don't want to go through the hassle of getting a couple unless I know they'll work.
Thanks for your help!
