It flies quite well. I have given it a good friend in Arizona. (Phil Pearce)

Nice one, I like that very much. Do we know the span for this model? I can't work out the right scaling on this one.

So I was going through my plans the other day when I came across a Gas Bird. I've always liked the design and often thought about building one. I did a quick web search, and came across a fantastic build log for the original 48" version. I converted it to two PDF files, because it's quite large, @117 pages, and have included it here for anyone else interested in this beautiful bird. By the way, the B&W picture at the top of the article, is a 150% size (built many years ago) by fellow club member Don Bekins. He gave it away a few years back in a raffle. I believe it's still flying with an OS .91 open rocker 4 stroke. I never saw it fly. Eut (California Condor) I'm sure you saw it, how'd it fly? He gave me the plans for it, but it's a VERY LARGE bird, to big for my shop!

AMA plans list on the web says 17 inches, and that's about what I measure on the plan. The MAN plans I've seen are 8 1/2 X 11 for each sheet.

Hey, channelmast. glad to see you like the Plato design. The wing was originally made from a glue-up of 1/8" balsa sheets to makle a 36" X 36" square. I think recommended power was between .19 to .30. An old Grid Leaks magazine had a small 3 view of a similar model using a Delta wing. Should make a fun ship, either version. Nothing fancy for a conversion to ERC. I'd probably go with elevons, rudder, and throttle today. In fact, both are on my to-do list. Since I think neither version showed a CG, I'd probably make a scale glider from sheet, trim it out for a good glide, and find the relative CG that way. It should transfer directly, at least for a ball park.

It was a very good flyer as I remember.

I was shure to have it!

Using the scale on page 1 of the plan and the measurement tool in Adobe I reckon the wing is made from 4" sheets and so the span would be 30"

MAN plans catalog and tissue

Gentlemen,

Among all those rescued plans I had was a copy of the January 1994 MAN plans catalog. It's just pic's and descriptions (and a little history) of the aircraft plans that are offered. There's a vintage section too.

I'll be happy to scan and post it if anyone is interested....may jog a memory of a plane or set of plans ......

Also, for all of us tissue guys, I've discovered what I think is a superior substitute for tissue.....Us old engineers, designers, and draftsmen called it onion skin. It weighs in at ~0.08 oz/ft2, comes in a 12" x 50' roll, cost about $6, shrinks well, takes both dope and paint well, and it appears to be 5 times stronger than tissue.
( I did a tear test of 1/2" wide strips......the tissue failed at 2 oz, the onion skin at 10)

See attached .jpg.....they don't call it onion skin anymore !

Calm winds

Funny you should mention this stuff...

I think it's what I'm using as a plan protector. See Photo 1...
