Brief:
This be t' 24mm version o' Joseph Peklicz's monocopter rocket. He has a 18mm version, shiver me timbers, 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, matey, and they were pre-shaped, and pre cut. T' single balsa blade is pre-coated with paper. Aye aye! This adds strength without t' additional weight. Avast! Begad! Instructions are hand drawn on a single sheet o' paper.
Construction be quick since everythin' except t' gluin' was done for you. Avast, me proud beauty! Avast! Gluin' t' motor tube t' t' center hub was t' most time consumin' process. Begad! Avast, me proud beauty! This be t' most critical part o' t' kit, me bucko, since t' force o' t' motor will try t' rip t' motor tube off o' t' hub. Well, blow me down! I decided t' use wood glue for this task. Begad! I did nay want t' extra weight o' epoxy. I did one modification t' me monocopter: I did nay install t' cardboard bulkhead that is placed against t' thrust ring. Aye aye! 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, I did nay paint me monocopter. Blimey! Begad! 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. I'd say that mine got about 30 ft with a D12-0. Avast! Blimey! For t' second flight, I used a E11-3J reload. Well, blow me down! Much better. Begad! Ya scallywag! 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. Aye aye! It flew fine, me bucko, but on t' way down, t' win' hit t' rope fence around t' pads. T' monocopter's win' was shattered beyond repair.
Recovery:
I think me monocopter was nay balanced. Well, blow me down! T' reason I say this it wandered in one direction. Ahoy! Ahoy! 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. Ya scallywag! Avast, me proud beauty! I liked t' way everythin' was pretty much done for you. Arrr! Flights are interestin' and unique. Begad! Aye aye! This rocket is well worth t' purchase.

T' followin' excerpt is from "Sport Rocketry". Well, blow me down! T' intention is t' allow guests t' get a basic feelin' about a kit. We strongly suggest that you get a copy o' t' referenced Sport Rocketry and read t' entire article. Avast, me proud beauty! Inside you will find many helpful hints in construction as well as other useful information. Avast! For more information, use t' two links above.
(Sport Rocketry - May/June 2001 - page 32 - by Mort Binstock)
"A monocopter is a one-blade helicopter, 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 be a disaster: t' main blade broke off and parts shredded everywhere... Avast, me proud beauty! Subsequent inspection revealed t' damage was nay severe and t' model was 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 was most rewarding. Ya scallywag! Blimey! T' repaired "D"izzy flew powered by a D12-5. Begad! Avast! Lift off be unusual and spectacular t' watch (look at it go!) with an estimated 50 ft. Aye aye! altitude."
"T' monocopter... Ya scallywag! Avast, me proud beauty! ascended with a quick and straight boost. Ahoy! T' monocopter then descended slowly, arrr, shiver me timbers, matey, experiencin' no further damage."
T' article also provides a brief history o' monocopters. Arrr! T' kit provides for a different launch and recovery than typical rocket kits.
