Greetings,

Haven't been on this forum for a long time, but with all this stay-at-home happening, I've been poking around and visited the Scale Forum here.

Attached below is a YouTube video of my 7X Upscale of the Estes X-Ray, about 11' ft tall.


I flew it on an Aerotech K700 White Lightening and it did very well. Tom the video guy for our Michigan Team 1 club edited a great video! Inside the clear section is my original X-Ray model from the mid 1970's. It is now the highest flying balsa rocket I ever made (albeit as a payload!).

A great upscale experience.

Nice! Fins got a little scary there for a moment.

How thick a rod is that? :eek:

Nice rocket and video. I like the editing. I always liked the X-Ray especially, but it's hard to put my finger on why. Is this the original paint scheme ?

I re-watched the video because I missed the scary fin. There it was, definitely scary.

Wow that was some wiggly fin action! What material were they made out of?

Can't ask for a nicer flight or video than that! I am curious, that's the largest rocket I've seen launched off what looks like a ROD. What was that, a 1" rod?

The wavy fins may be an artifact of the video process. We discussed this years ago on TRF.

Awesome flight and great vid. I love the original version hitching a lift in the payload bay. Classic!:cool:

That was quite a launch rod.:eek: Not so much a rod; more like bar stock.

It was MI Team 1's one inch thick rod, so yes... bar stock.
I scaled it true so fin flutter (3/16" G10 phenolic) set in at max Q. The 2560 N-S motor is a bit aggressive.

Yep, straight out of the 1975 catalog.

Yes! Good eye.
