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

Construction:
T' parts list:

• four carrugated cardboard triangles, ya bilge rat, me hearties, 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. T' motor support plate be a scrap piece o' 1/4" plywood. Well, blow me down! Before this was attached, I located t' motor tube locations and drilled a hole for t' lug. Begad! Blimey! As t' plate be epoxied into place, I measured t' distance t' each corner t' make sure it be even. T' find t' location o' t' launch lug hole in t' top of t' pyramid, shiver me timbers, shiver me timbers, I dry-fit a 1/4" lug and used a rod t' start a hole. Avast! Avast! I finished t' hole with a hobby knife. Aye aye! After the lug be 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. Avast, me proud beauty! 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. Aye aye! 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). Avast, me proud beauty! 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. Begad! Arrr! T' G38 flight be nice and smoky with t' low pressure area at its base clearly visible. Aye aye! T' E9s made for a slow boost and t' rocket seemed t' stop abruptly at burn-out. In both cases, t' pyramid fell nose first slowly t' t' ground.

   Summary:
   This was a simple, ya bilge rat, inexpensive, and fast build. Everyone who likes saucers, shiver me timbers, pyramids, matey, etc. Well, blow me down! should build one. Blimey! Not necessarily exactly like this one. Well, blow me down! You can even paint it :)
