1st scratch build

I recently came back after being out of the hobby for a long time. I have to say things have changed alot as far as resources go. Wish there'd been an internet when I was a kid. I found JimZ's site and love that I can build the rockets I grew up flying. One question though: I downloaded the plans to replace the photon disruptor I lost on it's maiden flight years ago and was wondering how I get the length of the different body tubes. I appreciate all your help in advance and I'll post pics when I get started building.

try the ninfinger site or Ye Olde Rocket Shoppe.

Thanks Jim, thats exactly what I needed. I hope to start building in a few days and will post pics of my progress.

Cool. Are you building the earlier Photon Disruptor or the later Photon Disruptor II? Don't forget to post those pictures!!!

Here is my 2.6" Photon Disruptor II

I'm rebuilding the original. I loved my first one. Even though it only flew once it went straight as an arrow and clean outa sight. I'm hoping to get an Estes designer pack in a few days and get started. After this I'd love to see about upscaling to a 24mm size, but I'm taking it one step at a time.

anybody know where I can find plans for the larger Photon Disrupter II?

Both the Photon disruptor #1282 and the Photon disruptor II # 2052 are available on the JimZ plans site.
