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