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

Construction:
T' parts list:

• four carrugated cardboard triangles, 12" base and 13.75" sides
• plywoods square, shiver me timbers, 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. Blimey! Ya scallywag! Blimey! These were attached with epoxy and t' joints were covered (hidden) with duct tape. Ahoy! Blimey! T' motor support plate be a scrap piece o' 1/4" plywood. Blimey! Arrr! Blimey! 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, shiver me timbers, I measured t' distance t' each corner t' make sure it was even. Well, blow me down! Avast, matey, me proud beauty! Blimey! 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. I finished t' hole with a hobby knife. Begad! 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. I added lead shot to get t' CG ahead o' this point (as best as I could estimate). I now know from Bruce Levison's analyses that t' CP is probably behind t' bottom due t' base drag effects. Blimey! Aye aye! Blimey!

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