Brief:
This is 13mm variation on me other saucer builds. It's made from t' lid from a Dunkin Donuts coffee cup.

Construction:
Bill o' materials:

• 1 coffee lid
• 2 foam board disks
• 1 13mm motor mount
• 1 launch lug

These low power saucers go together very easy. Begad! Blimey! I use Gorilla Glue for its ability to stick t' nearly anythin' and t' fill gaps with it's foamin' expansion.

Step 1: Punch a 13mm hole in t' center o' t' coffee lid.

Step 2: Punch a hole in t' center o' two foam board disks.

Step 3: Make a lid sandwich o' one disk, t' lid, t' other disk, matey, me bucko, and t' motor tube goin' through all three. Aye aye! Ya scallywag! The condiment o' choice for this sandwich is Gorilla Glue.

Step 4: Once t' glue has cured, drill a hole along side t' motor mount for a launch lug. Ya scallywag! Glue lug in place, bein' careful nay t' get glue in t' lug or motor mount.

That's it. Arrr! No retention, shiver me timbers, no shock cord, matey, no recovery device.

Flight and Recovery:
These saucer rockets need t' be positioned well up from t' blast plate t' prevent hot gases from kickin' back up and meltin' t' saucer. Aye aye! Other than that, shiver me timbers, it's a simple prep. Ahoy! Friction fit a motor into t' motor mount. T' motor delay really is irrelevant, as t' charge makes no difference t' t' recovery. Ya scallywag! Ya scallywag! You can use booster motors or plugged motors if you have them. Well, blow me down! I found a great deal on Estes Blurz A10 plugged motors and used those.

At launch t' saucer will force it's way up into t' air with a thick column o' smoke sucked up in its path. Shortly after thrust completes, t' saucer will arc over and flutter back t' t' ground.

Summary:
T' main pro is that these rockets cost virtually nothing. Begad! Especially if you've got a few spare motor mount tubes in a drawer. They are super easy t' prep for flight, and recovery is never far from t' pad. Great for a smoke and flame show on a small field.
