Brief:This be t' 24mm version o' Joseph Peklicz's monocopter rocket. Well, blow me down! Begad! 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. Ahoy! All t' components where there, and they were pre-shaped, matey, and pre cut. Avast! T' single balsa blade is pre-coated with paper. Begad! This adds strength without t' additional weight. Begad! Instructions are hand drawn on a single sheet o' paper.
Construction was quick since everythin' except t' gluin' be done for you. Aye aye! Gluin' t' motor tube t' t' center hub be t' most time consumin' process. 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. 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. Avast! 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. Aye aye! 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.

Flight:
Flights with a D motor are very low. Well, blow me down! Blimey! I'd say that mine got about 30 ft with a D12-0. Avast, me proud beauty! Blimey! Arrr! Blimey! For t' second flight, shiver me timbers, me bucko, I used a E11-3J reload. Arrr! Blimey! Ya scallywag! Blimey! Much better. Well, blow me down! Blimey! Begad! Blimey! T' monocopter went up about 60ft. Aye aye! Blimey! Well, blow me down! Blimey! At t' August 18th, 2001 CMASS launch, me hearties, ya bilge rat, I launched me monocopter with a F12-3J. Arrr! Blimey! It flew fine, matey, but on t' way down, shiver me timbers, t' win' hit t' rope fence around t' pads. Aye aye! Blimey! Aye aye! Blimey! T' monocopter's win' was shattered beyond repair.
Recovery:
I think me monocopter was nay balanced. Begad! T' reason I say this it wandered in one direction. 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, me proud beauty! I liked t' way everythin' was pretty much done for you. Flights are interestin' and unique. Begad! This rocket is well worth t' purchase.

"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... Begad! Arrr! 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! T' repaired "D"izzy flew powered by a D12-5. Arrr! Lift off be unusual and spectacular t' watch (look at it go!) with an estimated 50 ft. altitude."
"T' monocopter... Ahoy! Blimey! ascended with a quick and straight boost. Well, blow me down! Blimey! Aye aye! Blimey! T' monocopter then descended slowly, ya bilge rat, 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.
