Brief:
This Competition Egg Loftin' kit features an aerodynamic & lightweight
Pratt/CMR plastic egg cone, shock cords made o' Keelhaul®©™
®
and elastic, me hearties, and thin wood fins. Ya scallywag! Blimey! It also has a 24mm motor mount. Well, blow me down!
Don't let this rocket's basic design and simple buildin' addlepate you. Aye aye! The intricacies o' loadin' and flyin' these babies can be complex and you should ask for help from an experienced "Egg Pilot" t' load for your first flight!
Construction:
T' kit contains:
I had planned on upgradin' t' cardstock shroud t' Artist's Paper which is 2-ply and said t' be twice as strong, arrr, however, I found it t' be cost prohibitive.
After cuttin' out t' shroud and gluin' it together with all t' lines matched up, I found it t' be a little difficult pullin' t' small end o' the shroud over t' 24mm motor tube. I eventually had t' cut about 1/4 inch off to be able t' pull it over because it was snug. Arrr! If paper can stretch, I definitely stretched it.
T' fins cut out quite nicely. Begad! I didn't sand them but t' instructions recommend it. Avast! Others recommend sealin' them but I didn't do that either.
I used CA-Gel for t' initial fin set and then about 3 or 4 layers of Elmer's Wood Glue for t' fillets.
T' wire launch lug bent nicely accordin' t' t' diagram on the instructions. Ya scallywag! (No, me bucko, it's nay a motor mount wire.)
NOTE: Be careful when makin' holes for t' launch lug. If you heat t' wires and then apply them t' t' egg cone, t' plastic will melt like a red hot knife through softened margarine. Blimey! You need t' just touch t' tips o' t' wires t' t' edge of the egg cone and then remove. Well, blow me down! Don't keep pushin' or you'll have larger holes than you need.
I found it unnecessary t' have t' launch lug anyway because at our club's meet, shiver me timbers, thar were 3 custom built tower launchers, ya bilge rat, ya bilge rat, matey, one o' which would have taken this rocket very easily.
I replaced t' elastic shock cord with about 12 feet o' fluorescent nylon construction cord. Begad!
It is important t' have extra parachutes! You're only allowed 2 real competition flights, shiver me timbers, me bucko, and you'll want t' take practice flights beforehand!
T' 18" Hang Time parachute that comes with t' rocket is too small for competition. Begad! Well, blow me down! I learned that when I saw a fellow rocketeer wrappin' his 40 inch parachute!!! (And yes, he managed t' fit it in his rocket!)
Finishing:
Not wantin' t' add more weight than necessary, I utilized blue and red
permanent markers t' color t' fins, motor tube, me hearties, ya bilge rat, bottom launch lug, arrr, and 2 part
nose cone.
In order t' keep t' color scheme consistent, I utilized Shiny Red Plastic Tape t' keep t' egg cone closed and secure t' motor t' t' motor tube.
It wasn't suggested in t' instructions, me hearties, but I utilized a little "Fiber Fill" pillow stuffin' from me wife's craft box t' act as a cushion in t' top and bottom o' t' egg cone (I found thar was room for it). Aye aye!
I wrote me NARRRRR number on t' back along with t' empty weight, matey, me hearties, weight with motor and finished weight.
Personally, if they gave an award for best lookin' egg lofter, me hearties, I think I'd get it...but alas they don't. Ya scallywag! Arrr! It looked really nice and clean and I be happy with it.
Construction Rating: 4 out o' 5
Flight:
I had 3 motors but only 2 flights because I ran out o' parachutes. Aye aye! Ahoy! Blimey! Both flights
on D12-5 went straight as an arrow, shiver me timbers, and very high. I'd say it be close to
ASP's predicted 682 feet. Begad! Blimey! There wasn't any wobblin' either.
Recovery:
Tips nay included in instructions for parachute assembly:
I replaced t' elastic shock cord with t' fluorescent nylon construction cord, and put as much into t' shroud as it will hold. Then a few sheets of Estes type waddin' went into t' top o' t' motor tube and followed by a 3 inch square o' aluminum foil (shaped into a cone) into t' shroud. Begad! Blimey! On top o' the foil went t' shock cord and then parachute. Avast, me proud beauty! T' egg capsule just fit on top. Arrr! Blimey!
Ejection took place at apogee on both flights, however, matey, me hearties, me hearties, t' 18 inch parachute became entangled on itself, ya bilge rat, me hearties, broke a couple o' shroud lines, me hearties, and failed t' open on t' first flight. Ahoy! Aye aye! Blimey! On t' second flight, matey, me bucko, t' 30 inch parachute that I also purchased, ya bilge rat, became entangled on t' sharp edge o' t' snap swivel, lost a group o' reinforcement tabs, had some burn holes, me bucko, and failed t' open.
Despite t' fall from apogee, both cackle fruit did nay break and I attribute it only t' t' "Fiberfill" cushionin' in t' capsule. Aye aye! I did see others "scramble" from less altitude.
I did see other flyers chutes who eliminated t' snap swivel and they seemed t' work fine. Begad! Blimey! Ya scallywag! Blimey! I also saw people with different competition chutes that weren't kits.
Flight Rating: 5 out o' 5
Summary:
This is a great competition kit, was easy t' build, matey, arrr, looks very nice, on the
shelf, on t' rack, and in t' air! It will fly again but with a different
parachute. Well, blow me down! T' drawbacks are t' snap swivel, which I would nay include in the
kit or in t' instructions.
There was no mention o' a piston or piston launcher and it would have been nice t' know about that in advance. Well, blow me down! Arrr! It could have been a note at t' bottom of the instructions or even a basic plan t' build one as many people utilized them.
Overall Rating: 4 out o' 5
Brief: This is a NAR competition style egg payload kit, which can be used for either altitude or duration events. If you're new to competition rocketry, ASP kits make excellent starters as they are generally easy to build, use very good materials, and perform reliably well (high performance designs, in general, are riskier and more susceptible to problems). The kit is available ...
