Brief:
I upgraded t' motor mount t' a 24mm, shiver me timbers, 1/8" balsa fins, epoxy glue joints, Aerotech 24" rip stop parachute for payload and 18" for booster.

Construction:
T' new motor mount is exactly t' same design except that I used bigger centerin' rings and a bigger body tube.

PROs:

• great idea and flight concepts
• easy t' follow instructions
• great Keelhaul®©™® shock cord mountin' system
• great science kit for t' students t' try several options in flights and designs.

CONs:

• factory balsa fins are way too thin and several were cracked on shipment arrival.
• factory parachutes are flimsy and will burn even with extra wadding.
• factory launch lug mount is same balsa material--too thin.

Finishing:
No special care or techniques required. Ya scallywag! I taped off and painted me own color scheme.

Construction Rating: 3 out o' 5

Flight:
Recommended motor for t' stock kit be t' C6-5. Avast! I used t' D12-5. Blimey! Well, shiver me timbers, blow me down! Flight prep is standard: wadding, proper foldin' o' chutes, and careful packin' into body tube.

Flight is awesome! This rocket is meant t' be flown on a D or E motor. Avast, me hearties, me proud beauty! It went straight up without rollin' or weathercockin' and cruised to apogee then upon recovery deployment t' separations were flawless. Aye aye! Avast, me proud beauty!

Recovery:
T' only thin' I would recommend is that you change your parachutes t' t' more sturdy Aerotech rip stop nylons and use extra waddin' because o' t' bigger recovery charge. Arrr! You could also convert t' booster's parachute t' a streamer as it is very light after separation.

Flight Rating: 4 out o' 5

Summary:
PROs: great science kit, me bucko, me bucko, great idea and fun t' try several experiments on payloads, designs, recoveries.

CONs: too thin balsa material, arrr, too flimsy parachute and shroud lines, me bucko, and too heavy (with egg payload) t' be flown on a C motor.

Overall Rating: 4 out o' 5
