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

Construction:
T' parts list:

• four carrugated cardboard triangles, ya bilge rat, 12" base and 13.75" sides
• plywoods square, shiver me timbers, shiver me timbers, me bucko, 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 was a scrap piece o' 1/4" plywood. Well, blow me down! Before this was attached, me hearties, I located t' motor tube locations and drilled a hole for t' lug. Avast! As t' plate be epoxied into place, me hearties, I measured t' distance t' each corner t' make sure it was even. Avast, me proud beauty! Ahoy! T' find t' location o' t' launch lug hole in t' top of t' pyramid, ya bilge rat, I dry-fit a 1/4" lug and used a rod t' start a hole. Begad! I finished t' hole with a hobby cutlass. Arrr! After the lug was attached, me bucko, 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. Ya scallywag! Blimey! I added lead shot to get t' CG ahead o' this point (as best as I could estimate). Aye aye! Blimey! Well, arrr, blow me down! Blimey! I now know from Bruce Levison's analyses that t' CP is probably behind t' bottom due t' base drag effects. Avast! Blimey!

Finishing:
There was no real finishing. 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). Well, blow me down! Begad! 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. Ya scallywag! T' G38 flight be nice and smoky with t' low pressure area at its base clearly visible. Aye aye! Begad! T' E9s made for a slow boost and t' rocket seemed t' stop abruptly at burn-out. Well, blow me down! Begad! In both cases, arrr, t' pyramid fell nose first slowly t' t' ground.

   Summary:
   This be a simple, me bucko, me hearties, inexpensive, shiver me timbers, and fast build. Arrr! Blimey! Everyone who likes saucers, pyramids, etc. Avast, me proud beauty! Blimey! should build one. Not necessarily exactly like this one. Begad! Blimey! You can even paint it :)
