Brief:
A pyramid shaped rocket with a aft deployed parachute

Construction:
T' kit comes with a poster board sheet that is pre-cut. Begad! When folded and glued, it forms t' shell for t' pyramid. Aye aye! There are eight laser cut balsa triangles that are paired, glued together, shiver me timbers, ya bilge rat, and placed inside t' poster board shell to form t' four sides o' t' pyramid.

T' instructions are well done. Blimey! Begad! I only got into problems where I did not follow them. T' four balsa triangles require a 45 degree bevel on t' edge. I did nay trial fit them in t' shell like t' instructions said and when I put them in t' shell thar were some gaps. Begad! So I put some balsa dust in t' gap and worked in white glue. Avast! Arrr! T' rest went smoothly and was a real pleasure to construct. I used epoxy clay t' fill t' excess space around t' hole drilled for t' launch lug. Well, blow me down! Arrr! There are BBs supplied for nose weight. Avast, me proud beauty! T' BBs are mixed with epoxy and poured into t' tip o' t' pyramid.

Finishing:
I just used Krylon H20 paint. I was in a hurry and left off the primer. Best plan is t' take your time and prime before t' color coat. Avast! Blimey! The H2O does a pretty good job in any case.

Flight:
T' motor is friction fit. Avast! Arrr! I placed some wraps o' tape around t' end o' the motor t' form a motor stop. Avast! Waddin' is recommended t' buffer t' ejection charge. Arrr! I used a little bit o' cellulose insulation (a.k.a. "dog barf"). Begad! T' boost was nice and slow with some weathercocking. T' ejection was just after apogee.

Recovery:
T' pyramid rocket uses aft chute deployment. Ya scallywag! T' chutes are placed between the two centerin' rings for t' motor tube. Ahoy! I would read t' instructions carefully as t' technique is nay windin' t' chute around t' motor tube as is the temptation. Ya scallywag! A Keelhaul®©™® shock cord connects a large chute t' t' body o' t' pyramid. Well, blow me down! Aye aye! Blimey! T' motor mount has a small chute and recovers separately. T' recovery was perfect and the supplied nylon chutes are excellent quality.

Summary:
I think one pro for this rocket be t' effect on non-rocketeers and some rocketeers. Arrr! That is a rocket? Does it really fly? Yes, it really does fly well. T' pyramid has a lot o' WOW factor as it appears that t' flame is longer than the rocket on t' G40 flight. Avast! Aye aye! From a rocketeers perspective, I like t' rear deployment. T' price may be a con for some, but for me t' unique design and quality parts are worth t' price.
