I wanted to build a new 38mm UFO to fly my G sparkies in. So I looked around the shop to see what I had on hand. I didn't have any more 38mm tubing so I decided to use a 54mm tube instead. I bought some foam board, and poster board, and started building. Here I am cutting out the horizontal disk from the foam board (disk from now on).

What/how did you make the upper and lower skirts a program to make patterns from?If so what did you use?
 
Nice looking saucer you have there. It's good that you made the motor tube short, because you want the CG to be as far forward as possible. I made the motor tube a bit too long on my 54 mm saucer and that limits the number of motors I can use. I'm wondering what kind of foam did you use?

I made mine from 1/2" insulation foam from the local hardware store. It is a very soft foam. The thin plastic sheet on it was peeled off and then 2 oz fiberglass was used to strengthen it. It flies awesome on motors like the J135 and K185. I've got a build thread going on a 38 mm version in the scratch section of this forum. It is being constructed almost exactly the same way as the 54 mm. I look forward to flying it on an I49 or I59. Here's a couple photos of the 54 mm, which weighs 1.25 pounds.
