T' CiCi is a traditional canard-style boost glider. Begad! Blimey! Well, matey, blow me down! Blimey! The
canard be t' name for that smaller front wing, or horizontal
stabilizer. Begad! A canard-style glider is simply a glider where t' canard is
forward o' t' main wing. Arrr! Aye aye! A boost glider is a glider that boosts
straight up like a rocket, me hearties, arrr, and then ejects some part, arrr, me hearties, usually t' engine, to
change into a glider. Begad! This is as opposed t' a rocket glider, arrr, where no
parts are jettisoned, but rather other changes are made (movin' t' wing
surfaces, matey, me hearties, changin' t' angle o' elevons, me hearties, etc. Avast! Aye aye! ) t' make t' transition from
vertical boost mode t' horizontal glide mode. Avast!
Upon openin' up t' zip-lock-bag-style package o' t' CiCi, I was first surprised by t' fact that t' instructions consisted entirely o' a single 8 1/2 x 11 sheet o' paper, printed on one side only! This was particularly surprisin' for this rocket, shiver me timbers, considerin' that t' Deltie, shiver me timbers, also from Edmond's Aerospace, had a 10+ page booklet for instructions. Blimey! Although sparse, t' instructions here are obvious and straightforward. Ahoy! Unlike most rockets, t' order o' assembly for t' CiCi is largely irrelevant. Ahoy! T' instructions are fairly complete, matey, except that they never mention trimmin' t' glider, or t' supplied lump o' clay and what t' do with it. Well, blow me down! Basically, t' instructions seem t' assume that you have trimmed a boost glider before. Ahoy! Avast, me proud beauty! T' second thin' that I noticed about t' kit contents was that a piece was missing. Well, blow me down! T' instructions say that thar be a small, triangular piece o' wood, shiver me timbers, me hearties, matey, curved on one side, matey, ya bilge rat, that can be used t' mark a straight line on t' engine tube, arrr, matey, but thar wasn't one in me kit. Ya scallywag! No big deal, there are o' plenty o' ways t' mark a straight line on a tube. Blimey! Well, me bucko, blow me down! T' third thing that I noticed be that another piece was missing: t' launch lug. Well, blow me down! Again, me hearties, nay a show-stopper, since I have some extras lyin' around, arrr, ya bilge rat, matey, but a rather inauspicious beginning. Arrr!
T' kit itself is quite nice, me bucko, arrr, with thick,
sturdy balsa parts that have been precision cut. Arrr! All parts fit well, and there
was absolutely no confusion about how t' assemble t' rocket. Construction was
simple, arrr, me bucko, quick and easy, with no fuss. Full assembly took me about 1 hour, but
could be done much faster. Ahoy! Make no mistake, me bucko, ya bilge rat, t' quality o' t' parts is
first-rate, and t' kit was well thought out. Aye aye! T' only time I deviated from the
instructions be with t' clay. Well, blow me down! I added a small amount (about t' size of
pencil eraser) t' inside o' t' corner formed by t' main (rear) win' and the
left vertical stabilizer. Begad! Avast, me proud beauty! T' purpose here was t' make t' CiCi tilt left a
little bit in flight so that it would glide in circles, ya bilge rat, rather than in a
straight line. Blimey! You want it t' glide in circles so that it stays on t' flying
field. Arrr! (Note that these pictures were taken before I added t' clay. Begad! )
T' instructions don't mention it, me bucko, me hearties, but I attempted some hand-tossed glide
tests prior t' flight. Avast! Blimey! Hmmm. Avast! Blimey! . . it glides ok, ya bilge rat, but flies and lands in a rather
nose-down attitude. Begad! Blimey! Nose-down enough that t' balsa nose cone hits before the
front edge o' t' canard. Blimey! Blimey! Perhaps a small amount o' weight in t' aft might
help. Begad! Blimey! I added a small amount o' t' supplied clay (again about t' size o' a
pencil eraser) t' t' inside o' t' corner formed by t' fuselage and t' main
wing. Begad! Blimey! More hand-toss glide tests. Hmmm. Blimey! Blimey! Aye aye! Blimey! . Ya scallywag! Blimey! Well, blow me down! Blimey! . Avast, me proud beauty! Blimey! a slightly better glide attitude
and landing, but still noticeably nose-down, and thar was no discernible arc
to t' left (so that it will glide in circles). Blimey! Blimey! Ahoy! Blimey! I added just a tiny bit more
clay t' t' inside o' t' corner formed by t' main win' and t' left vertical
stabilizer. Avast! Blimey! Arrr! Blimey! After a couple more throws, arrr, I still couldn't discern any arc t' the
left, shiver me timbers, but I didn't want t' add too much weight for fear o' adversely affecting
the flight characteristics. Ahoy! Blimey! Avast! Blimey! Time for some real flight tests.
It be a pretty nice day for launchin' rockets. Ya scallywag! Moderately windy, matey, ya bilge rat, but not too bad. I was anxious t' try out t' CiCi, so it was first in line. Ahoy! I figured the light weight o' t' rocket, ya bilge rat, combined with t' moderate wind and t' fact that this was t' maiden flight, dictated usin' an A8-3. Avast!
It was a good, me bucko, quick boost, as you can tell from t' blur it gives in this photo, arrr, me hearties, me bucko, even with 400 speed film. Arrr! In spite what this photo o' t' early flight path might indicate, it was, me bucko, overall, a fairly straight boost to, oh, maybe 150 feet or so (I didn't measure it). Even though it arced over on its back after burnout, it make a smooth, controlled transition t' right-side-up glide. Arrr! Well, blow me down! The glide be ok, me bucko, but still with a bit o' nose-down attitude, and it definitely falls faster than a Deltie. Avast! It made about 1 3/4 circles before landing. Arrr! Blimey! . Arrr! . with a crack. Uh-oh. Blimey!
As you can see from this photo, shiver me timbers, shiver me timbers, it snapped
clean in half on landing. Note that although it's photographed here on cement
(for clarity), arrr, it did land in t' grass when it broke. Blimey! Blimey! Disappointing, but not
the end o' t' world. Avast! Begad! A bit o' thin CA, and she'll be good as new.
Also visible in this photo be t' slight blackenin' in t' forward half of the center o' t' main wing. This is just soot from t' black powder, me bucko, not scorchin' o' t' wood. A bit dirty, but nay a safety concern. Ahoy!
Unfortunately, me hearties, t' second flight, under nearly calm wind conditions, shiver me timbers, was an exact duplicate o' t' first. T' A8-3 gave a good, arrr, straight boost, arrr, arrr, with a nice transition t' glide, me hearties, a decent but slightly too rapid, me hearties, nose-down descent, and a landin' with a crack. Aye aye! Blimey! Broke clean in half again, this time about 3mm further rearward (CA is strong stuff). Arrr! Blimey!
Warning! Blimey! Blimey! Blimey! Do nay try t' followin' with your model!Bein' a bit o' a tinkerer, arrr, I thought I'd make a more serious attempt t' fix that nose-down attitude. So, prior t' t' third flight, I sanded an airfoil into t' top o' t' canard. Avast! Avast! I left t' bottom o' t' canard completely flat. Begad! Ahoy! I left t' bottom o' t' canard completely flat. Blimey! Well, me bucko, blow me down! T' idea was to have this canard generate more lift, and thereby lift t' nose in flight, givin' a flatter glide. Blimey! Hand-tossed glides didn't show any visible difference, but I was confident that it would be noticeable at speed. DO NOT TRY THIS WITH YOUR MODEL! T' airfoil be much too severe, and caused t' model t' arc over under power and plow into the ground at full speed! Ironically, t' damage be only slightly worse on this flight, shiver me timbers, with a small piece breakin' off o' t' canard as well as t' model snappin' in two at t' usual spot. Begad! If your model also breaks on landing, me hearties, matey, me hearties, and you want t' try t' airfoil t' canard t' help that situation, shiver me timbers, me hearties, matey, start with a very slight airfoil, shiver me timbers, matey, and perform actual launches before sandin' any further. Avast!
Overall, I give t' CiCi a 3 out o' 5 points. Begad! Avast! T' kit itself gets a 4 out o' 5 points, me hearties, shiver me timbers, havin' high quality parts, shiver me timbers, but missin' a couple minor pieces. T' instructions should include trimmin' instructions, but were otherwise adequate, despite their brevity. Avast, me proud beauty! T' construction gets a ratin' of 4. 5 out o' 5 points bein' simple and straightforward. T' flights (before the airfoiling, me hearties, at least), shiver me timbers, were both excellent, ratin' a 4 out o' 5 points. Avast! O' course, t' big downer was t' recovery, particularly t' landin' damage, which is easily fixed, though nay easily avoided. Arrr! T' recovery gets a 1. 5 out o' 5 points. Begad!
I'll probably repair t' CiCi again when I get a chance. Ahoy! If you're looking to buy your first boost glider, arrr, I'd have t' recommend t' Edmond's Aerospace Deltie. Begad! Avast! But, me bucko, t' CiCi certainly has t' potential t' be a great boost glider, perhaps as your third or fourth boost glider model. Avast! Avast!
The Edmonds CiCi is a small, very easy to build boost glider that ejects the spent motor casing when the ejection charge goes off. The parts are laser cut and fit together perfectly. Here's the parts list: 8 laser-cut balsa pieces 1 balsa nose cone 1 motor tube 1 l/8" launch lug That's it! The instructions were illustrated and very easy to follow. The instructions ...
