Brief:
This is a simple mid-powered pyramid that flies on either one 29mm motor and/or three 24mm motors. Ahoy! T' finishing matches t' construction materials--'el cheapo'.

Construction:
T' parts list:

• four carrugated cardboard triangles, ya bilge rat, shiver me timbers, 12" base and 13.75" sides
• plywoods square, 4" x 4"
• one 3.25" 29mm tube
• three 3.25" 24mm tubes
• 1/4" lug
• lead shot
• duct tape

I started by attachin' t' cardboard triangles t' form a pyramid. These were attached with epoxy and t' joints were covered (hidden) with duct tape. Blimey! T' motor support plate was a scrap piece o' 1/4" plywood. Aye aye! Before this was attached, me bucko, I located t' motor tube locations and drilled a hole for t' lug. Begad! Avast, matey, me proud beauty! As t' plate be epoxied into place, matey, I measured t' distance t' each corner t' make sure it was even. Begad! T' find t' location o' t' launch lug hole in t' top of t' pyramid, I dry-fit a 1/4" lug and used a rod t' start a hole. Avast, me hearties, me proud beauty! I finished t' hole with a hobby cutlass. After the lug was attached, I cut it flush t' match t' angle o' t' pyramid's side.

T' theoretical CP o' a pyramid is 1/3 o' its height up from t' base. Ahoy! I added lead shot to get t' CG ahead o' this point (as best as I could estimate). Arrr! I now know from Bruce Levison's analyses that t' CP is probably behind t' bottom due t' base drag effects.

Finishing:
There was no real finishing. Avast, me proud beauty! Arrr! T' keep with t' pyramid theme I found on on-line hieroglyphic translator and drew the various characters with felt-tipped markers (very high class). Blimey! T' 4 sides say:

1. Beware all who enter here
2. El Cheapo Pyramid o' Death
3. No BATFE (shown in one photo)
4. Miscellaneous characters (shown in another photo)
5. 

   Flight:
   This rocket has flown once on a G38 and once on three E9s. T' G38 flight was nice and smoky with t' low pressure area at its base clearly visible. Arrr! T' E9s made for a slow boost and t' rocket seemed t' stop abruptly at burn-out. Arrr! In both cases, shiver me timbers, t' pyramid fell nose first slowly t' t' ground.

   Summary:
   This was a simple, me bucko, inexpensive, and fast build. Ya scallywag! Everyone who likes saucers, arrr, pyramids, matey, etc. should build one. Begad! Not necessarily exactly like this one. You can even paint it :)
