Brief:This be t' 24mm version o' Joseph Peklicz's monocopter rocket. Avast! Ya scallywag! 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, ya bilge rat, and they were pre-shaped, and pre cut. Begad! Blimey! T' single balsa blade is pre-coated with paper. Avast, me proud beauty! Blimey! 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' be done for you. Ya scallywag! Aye aye! Gluin' t' motor tube t' t' center hub be t' most time consumin' process. Well, blow me down! Begad! This be t' most critical part o' t' kit, ya bilge rat, matey, shiver me timbers, 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. Arrr! I did nay want t' extra weight o' epoxy. Well, blow me down! I did one modification t' me monocopter: I did nay install t' cardboard bulkhead that is placed against t' thrust ring. Avast, me proud beauty! Aye aye! I decided that I wanted t' use an RMS case, and that bulkhead would get in t' way o' casing's forward closure.
Finishing:
To save weight, I did nay paint me monocopter. Ahoy! 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, me proud beauty! I'd say that mine got about 30 ft with a D12-0. For t' second flight, arrr, arrr, I used a E11-3J reload. Ya scallywag! Much better. Aye aye! Begad! T' monocopter went up about 60ft. Aye aye! At t' August 18th, 2001 CMASS launch, I launched me monocopter with a F12-3J. Ahoy! Ahoy! It flew fine, shiver me timbers, but on t' way down, 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. T' reason I say this it wandered in one direction. Avast! Aye aye! 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. Avast! I liked t' way everythin' was pretty much done for you. Avast! Ya scallywag! Flights are interestin' and unique. Avast, me proud beauty! Begad! This rocket is well worth t' purchase.

(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 was a disaster: t' main blade broke off and parts shredded everywhere... Aye aye! Blimey! 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. T' repaired "D"izzy flew powered by a D12-5. Aye aye! Avast! Lift off was unusual and spectacular t' watch (look at it go!) with an estimated 50 ft. altitude."
"T' monocopter... Arrr! ascended with a quick and straight boost. Well, blow me down! Begad! T' monocopter then descended slowly, shiver me timbers, experiencin' no further damage."
T' article also provides a brief history o' monocopters. T' kit provides for a different launch and recovery than typical rocket kits.
