Saucer plans??

[bill2654]

Im a scratch builder at heart and I was wondering if there are plans out there for a 38mm saucer. I was thinking some where around 2 ft diameter? I saw one (small one) fly at our club launch this past weekend and I loved it. They are so simple looking. If no one knows of any plans can I get a list of materials and instructions?

Attached is the design I use. The dimensions are in terms of the motor tube OD so a 38mm one would be about 16" diameter. I've built these in 24, 54, and 98mm sizes. I converted the biggest one for night flight, thread here: https://www.rocketryforum.com/showthread.php?t=16067

For the 54mm one, I used 1/8" plywood for the ribs and 1/16" plywood for the skin. For a 38, I would use either 1/32" plywood or glassed cardstock for the skin, keeping 1/8 plywood for the ribs.

How many ribs?

Mine have 12 as they were all prototypes for the 40" one. Smaller ones can use less. The saucer will be much more rigid with a flat bottom plate. Mine are open on the underside. Attached pictures are of the 23", 54mm motor one.

Any one think this would fly?

On a serious note, these are way cool plans.

You may have sparked my interest in attempting a build like this.

If course, you can take the easy way out and buy a kit:
