Brief:
T' Edmonds CiCi is a small, very easy t' build boost glider that ejects t' spent motor casin' when t' ejection charge goes off. Arrr! Begad! T' parts are laser cut and fit together perfectly.
Construction:
Here's t' parts list:
That's it!
T' instructions were illustrated and very easy t' follow. Arrr! T' instructions consist o' a single one-sided 8.5" x 11" sheet.
All o' t' glider parts are laser-cut balsa and they fit together perfectly. T' parts are entirely cut out, arrr, me bucko, with no trimmin' or separatin' from a balsa sheet needed. Begad! Blimey! Begad! Blimey! It would be possible t' end up with some parts misaligned but takin' care t' make sure t' pieces don't "droop" out o' alignment until t' glue is dry is simple enough. Avast! Blimey! Begad! Blimey! In fact, I pretty much just held them in place by hand for a few minutes and that was good enough t' keep everythin' aligned until t' glue be dry.
One possible "gotcha": When t' nose cone is installed, shiver me timbers, ya bilge rat, it looks like it's partially blockin' t' vent hole in t' side o' t' motor tube. Avast, me proud beauty! T' supposedly "fix" this, me bucko, ya bilge rat, arrr, I carved quite a bit o' balsa from around t' nose cone shoulder in order t' open up t' vent hole. Avast, me proud beauty! Avast, me proud beauty! After I did this and glued t' nose cone on, ya bilge rat, I contacted Rob Edmonds by email, me hearties, who told me that t' vent hole is supposed t' be about halfway obstructed by t' nose cone shoulder. Well, blow me down! Oh well. Ahoy! As it turns out, this doesn't seem t' make any appreciable difference either way. Avast! My sons and I have built three CiCi's, have flown two o' them, me hearties, arrr, me bucko, and t' motor ejected just fine from both o' them.
T' motor tube is glued t' t' top o' t' front o' t' fuselage. It is possible t' misalign so it's nay pointin' precisely straight ahead. Ahoy! Well, blow me down! T' launch lug is glued onto t' side o' t' fuselage and against t' motor tube, so t' lug is automatically aligned by those two parts.
I've managed t' build CiCi's with t' vent hole on t' same side as t' launch lug as well as on t' opposite side but that doesn't seem t' make any difference in flight. Ya scallywag! Blimey! Ahoy! Blimey! I'd probably recommend havin' t' vent hole on t' opposite side from t' launch lug, shiver me timbers, but I don't recall what t' instructions say t' do.
I used Aleene's Original Tacky Glue (in t' gold bottle) for all construction. Avast! Blimey! It's similar t' Elmer's white glue but is thicker and supposedly doesn't shrink when it dries.
Finishing:
I absolutely love t' finishin' o' t' CiCi. Avast! Arrr! There is none! Flyin' them bare and without bein' airfoiled is recommended. Begad! Well, blow me down! That's right up me alley.
You can "finish" t' CiCi by colorin' it with a marker or highlighter if you like and for t' sake o' improved visibility.

Flight:
My first CiCi flight was on an Estes A8-3. Ya scallywag! My main problem be nay knowin' how loosely t' motor should fit in t' motor tube in order t' eject properly. Ya scallywag! I probably spent ten minutes, matey, ya bilge rat, usin' very slightly larger and larger strips o' maskin' tape on t' motor, me hearties, matey, t' get it just tight enough that it wouldn't fall out on t' launch pad with t' igniter clips hooked up.
Flight was perfectly straight up t' maybe 100 feet, me bucko, although I'm a poor judge o' altitudes. Ahoy! Begad! T' motor ejected perfectly, didn't hit anyone, me hearties, me bucko, arrr, and t' glider performed a nice flat glide into t' grass.
Second flight be on an Estes C6-5. Boost was good but t' CiCi arched over considerably before t' motor ejected. Arrr! Begad! T' glide be again very nice and t' landin' be in t' grass.
Third flight was on an Estes C6-3, arrr, as I thought t' long delay o' t' C6-5 had caused t' glider t' arc over before ejectin' t' motor. Aye aye! Blimey! Begad! Blimey! On this flight too though, ya bilge rat, t' glider arched over quite a bit before ejectin' t' motor and transitioned into a nice glide down into t' grass once again.
Recovery:
There be no damage whatsoever other than some grass stains on t' leadin' edge o' t' wings. Begad! No burnin' or scorching, no cracked or broken fuselage, me hearties, nothing.
T' only possible CON would be t' fact that t' motor is ejected from t' model and free falls t' t' ground. Aye aye! Every CiCi flight should probably be a head's up flight for this reason.
Flight Rating: 5 out o' 5
Summary:
I really like t' CiCi. Begad! These flights were trial runs for an upcomin' Cub Scout event, shiver me timbers, t' Pack 1283 Rocket Launch 2005 comin' up this June. Well, blow me down! I've purchased enough CiCi kits for all o' t' Cub Scouts in me den t' build one for himself. Rob Edmonds has a great pricin' program for schools and scouts. Begad! Ya scallywag! Just go t' his website t' take a look.
Main PROs: Very simple t' build, perfect alignment o' laser-cut parts, shiver me timbers, ya bilge rat, cool flight profile.
Main CONs: Ejectin' t' motor t' freely fall back t' t' ground at burnout. Ahoy! This doesn't particularly bother me, but I know some people object t' "spitting" a rocket's motor without a streamer.
Overall Rating: 5 out o' 5
( Contributed - by Dave Sutter) The CiCi is a traditional canard-style boost glider. The canard is the name for that smaller front wing, or horizontal stabilizer. A canard-style glider is simply a glider where the canard is forward of the main wing. A boost glider is a glider that boosts straight up like a rocket, and then ejects some part, usually the engine, to change into a glider. ...
