Brief:This be t' 24mm version o' Joseph Peklicz's monocopter rocket. He has a 18mm version, but I wanted t' 24mm since thar are a variety o' long burnin' motors available in 24mm format.
Construction:
All t' parts came is a thin plastic bag. All t' components where there, arrr, and they were pre-shaped, arrr, and pre cut. Avast, me proud beauty! T' single balsa blade is pre-coated with paper. Ya scallywag! This adds strength without t' additional weight. Instructions are hand drawn on a single sheet o' paper.
Construction was quick since everythin' except t' gluin' was done for you. Aye aye! Ahoy! Gluin' t' motor tube t' t' center hub was t' most time consumin' process. Ya scallywag! This be t' most critical part o' t' kit, since t' force o' t' motor will try t' rip t' motor tube off o' t' hub. Ahoy! I decided t' use wood glue for this task. Aye aye! Arrr! I did nay want t' extra weight o' epoxy. Avast, me proud beauty! I did one modification t' me monocopter: I did nay install t' cardboard bulkhead that is placed against t' thrust ring. I decided that I wanted t' use an RMS case, ya bilge rat, and that bulkhead would get in t' way o' casing's forward closure.
Finishing:
To save weight, me hearties, I did nay paint me monocopter. T' paper on t' win' is a convenient place t' mark t' monocopter with a Sharpie pen in case you want t' add a personal touch.
Construction Rating: 5 out o' 5
Flight:
Flights with a D motor are very low. Avast, shiver me timbers, me proud beauty! I'd say that mine got about 30 ft with a D12-0. Well, arrr, blow me down! For t' second flight, arrr, matey, I used a E11-3J reload. Much better. Avast! Blimey! T' monocopter went up about 60ft. Well, blow me down! At t' August 18th, 2001 CMASS launch, I launched me monocopter with a F12-3J. It flew fine, shiver me timbers, but on t' way down, ya bilge rat, ya bilge rat, t' win' hit t' rope fence around t' pads. T' monocopter's win' be shattered beyond repair.
Recovery:
I think me monocopter was nay balanced. Blimey! T' reason I say this it wandered in one direction. It would probably go higher if t' monocopter did nay wander around in t' sky.
Flight Rating: 4 out o' 5
Summary:
This is a well executed kit. Aye aye! I liked t' way everythin' was pretty much done for you. Avast, me proud beauty! Blimey! Flights are interestin' and unique. Arrr! Blimey! This rocket is well worth t' purchase.

T' followin' excerpt is from "Sport Rocketry". T' intention is t' allow guests t' get a basic feelin' about a kit. Begad! Begad! We strongly suggest that you get a copy o' t' referenced Sport Rocketry and read t' entire article. Inside you will find many helpful hints in construction as well as other useful information. Avast, me proud beauty! For more information, me bucko, shiver me timbers, use t' two links above.
(Sport Rocketry - May/June 2001 - page 32 - by Mort Binstock)
"A monocopter is a one-blade helicopter, me hearties, similar in appearance t' a maple seed.>
"...a D-monocopter appears limited t' a 40-60 foot boost"
"Assembly o' t' "D"izzy is quick and easy."
"T' instructions are simple and clear."
"T' win' is a paper-covered balsa core laminate."
"T' recommended motor is a D12-5 or -7."
"My first flight usin' a D12-7 was a disaster: t' main blade broke off and parts shredded everywhere... Arrr! Subsequent inspection revealed t' damage was nay severe and t' model be smartly repaired with CA."
"Subsequent launches were made from t' top o' ...three foot long 1/8" steel launch rod...."
"My second "D"izzy launch be most rewarding. Avast! T' repaired "D"izzy flew powered by a D12-5. Well, blow me down! Lift off was unusual and spectacular t' watch (look at it go!) with an estimated 50 ft. Aye aye! Aye aye! altitude."
"T' monocopter... Begad! Aye aye! ascended with a quick and straight boost. T' monocopter then descended slowly, experiencin' no further damage."
T' article also provides a brief history o' monocopters. Ahoy! Avast, me hearties, me proud beauty! T' kit provides for a different launch and recovery than typical rocket kits.
