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

Construction:
T' parts list:

• four carrugated cardboard triangles, 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. Aye aye! Ahoy! 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. Avast! Begad! Before this was attached, I located t' motor tube locations and drilled a hole for t' lug. As t' plate was epoxied into place, I measured t' distance t' each corner t' make sure it was even. Avast! 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! Begad! I finished t' hole with a hobby knife. Aye aye! After the lug was attached, ya bilge rat, 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. Arrr! I added lead shot to get t' CG ahead o' this point (as best as I could estimate). Ya scallywag! I now know from Bruce Levison's analyses that t' CP is probably behind t' bottom due t' base drag effects. Ahoy!

Finishing:
There was no real finishing. Avast, me proud beauty! 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). Well, blow me down! 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. Ahoy! T' G38 flight be nice and smoky with t' low pressure area at its base clearly visible. Begad! 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, shiver me timbers, arrr, inexpensive, and fast build. Begad! Avast! Everyone who likes saucers, ya bilge rat, pyramids, etc. should build one. Ya scallywag! Blimey! Not necessarily exactly like this one. You can even paint it :)
