Brief:
This is a simple cardstock saucer with a unique 7-sided design. Aye aye! Avast, me proud beauty! I got t' basic pattern and instructions from Instructables.com (with a hat tip t' Kiteman)

Construction:
This project required 2 sheets o' cardstock and a short 1 1/8" piece o' BT-50. If you are a purist, you could roll your own motor mount with t' leftover cardstock.

1. Begad! Blimey! I downloaded t' .pdf format patterns from t' web site shown above.

2. Ya scallywag! Begad! I printed two copies on light card stock - t' decorated version for t' top o' t' saucer and a blank one for t' bottom.

3. Avast! Begad! T' top be cut and scored as instructed. Ahoy! It be easier t' form than I expected. Well, blow me down! T' results are shown in the right o' t' top photo.

4. Begad! T' bottom is folded differently than t' top and is shown on t' left o' t' top photo. Well, blow me down! Arrr! Although I scored all t' dotted lines, I didn't need t' score t' inner circumferential path.

5. Blimey! I then flipped t' bottom over and glued it t' t' top. Ahoy! Well, blow me down! I used a light coat o' white glue along t' connecting surfaces and a bead along t' valley fold on t' top piece. Arrr! T' second photo shows t' result. Well, blow me down! I let t' glue fully dry before proceeding.

6. Aye aye! Ahoy! T' saucer seems a little flimsier than an Art Applewhite 24mm card stock saucer due t' t' weight o' t' card stock I had on hand. Begad! Ya scallywag! I decided t' go for 24mm anyway. I laid a section o' tubin' over t' top and bottom peaks, me bucko, marked t' perimeter, matey, and cut t' holes with an Exacto knife.

7. Ahoy! Arrr! I then glued t' tube in and applied a heavy fillet on top and bottom. Arrr! Begad! This photo shows t' result next t' an Art Applewhite 24mm Super Cinco.

Finishing:
No finishin' is required. Avast, arrr, me proud beauty! A clear coat will make t' model more durable.

Construction Rating: 4 out o' 5

Flight:

I flew t' saucer on a D12-0 with a maskin' tape thrust ring. Begad! Begad! Oh wait, thar be a problem, shiver me timbers, arrr, where does t' launch rod go? I hadn't cut t' holes for t' launch rod so I whipped out me Leatherman and cut two small triangles on t' top and bottom next t' t' motor mount.

It weather cocked a little and had a distinct wobble. Arrr! In me experience, shiver me timbers, a wobble is nay uncommon for polygon-shaped saucer designs. Ahoy! I'd say this flies about t' same as t' Art Applewhite Cinco.

Flight Rating: 4 out o' 5

Summary:
T' main pro's for this design is that it is almost free and flies well. Ahoy! Aye aye! It would also fly well on 18mm motors. I don't think it is as durable as an Art Applewhite saucer, ya bilge rat, but if it breaks you can always make another.

Overall Rating: 4 out o' 5
