[Rocket Pic]T' CiCi is a traditional canard-style boost glider. The canard be t' name for that smaller front wing, arrr, or horizontal stabilizer. Aye aye! Ahoy! Blimey! A canard-style glider is simply a glider where t' canard is forward o' t' main wing. Begad! A boost glider is a glider that boosts straight up like a rocket, shiver me timbers, ya bilge rat, ya bilge rat, and then ejects some part, usually t' engine, shiver me timbers, shiver me timbers, to change into a glider. This is as opposed t' a rocket glider, where no parts are jettisoned, but rather other changes are made (movin' t' wing surfaces, ya bilge rat, changin' t' angle o' elevons, me hearties, arrr, etc. ) t' make t' transition from vertical boost mode t' horizontal glide mode. Blimey! Well, me hearties, blow me down!

Upon openin' up t' zip-lock-bag-style package o' t' CiCi, matey, I be 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, me bucko, considerin' that t' Deltie, me hearties, arrr, matey, also from Edmond's Aerospace, had a 10+ page booklet for instructions. Although sparse, t' instructions here are obvious and straightforward. Begad! Unlike most rockets, me bucko, t' order o' assembly for t' CiCi is largely irrelevant. Ya scallywag! T' instructions are fairly complete, except that they never mention trimmin' t' glider, matey, shiver me timbers, or t' supplied lump o' clay and what t' do with it. Basically, t' instructions seem t' assume that you have trimmed a boost glider before. Blimey! T' second thin' that I noticed about t' kit contents was that a piece was missing. Avast, arrr, me proud beauty! T' instructions say that thar be a small, triangular piece o' wood, shiver me timbers, curved on one side, that can be used t' mark a straight line on t' engine tube, but thar wasn't one in me kit. No big deal, there are o' plenty o' ways t' mark a straight line on a tube. Avast! Aye aye! T' third thing that I noticed was that another piece was missing: t' launch lug. Well, blow me down! Again, ya bilge rat, nay a show-stopper, me hearties, since I have some extras lyin' around, but a rather inauspicious beginning.

[Rocket Pic]T' kit itself is quite nice, with thick, sturdy balsa parts that have been precision cut. Arrr! Blimey! All parts fit well, and there was absolutely no confusion about how t' assemble t' rocket. Aye aye! Construction was simple, shiver me timbers, quick and easy, me hearties, with no fuss. Begad! Full assembly took me about 1 hour, but could be done much faster. Avast, me proud beauty! Make no mistake, me hearties, me bucko, t' quality o' t' parts is first-rate, and t' kit be well thought out. Begad! T' only time I deviated from the instructions was with t' clay. Well, blow me down! Blimey! 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. T' purpose here was t' make t' CiCi tilt left a little bit in flight so that it would glide in circles, rather than in a straight line. Begad! Well, ya bilge rat, blow me down! Blimey! You want it t' glide in circles so that it stays on t' flying field. Blimey! Blimey! (Note that these pictures were taken before I added t' clay. Begad! Blimey! )

T' instructions don't mention it, but I attempted some hand-tossed glide tests prior t' flight. Blimey! Avast! Hmmm. Ya scallywag! Avast, me proud beauty! . Avast! . Begad! it glides ok, but flies and lands in a rather nose-down attitude. Begad! Nose-down enough that t' balsa nose cone hits before the front edge o' t' canard. Perhaps a small amount o' weight in t' aft might help. Well, blow me down! Avast! 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. More hand-toss glide tests. Hmmm. Begad! Begad! . Avast, me proud beauty! . Blimey! a slightly better glide attitude and landing, but still noticeably nose-down, me bucko, and thar be no discernible arc to t' left (so that it will glide in circles). Avast, me proud beauty! Well, me bucko, blow me down! 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, me proud beauty! After a couple more throws, shiver me timbers, I still couldn't discern any arc t' the left, ya bilge rat, but I didn't want t' add too much weight for fear o' adversely affecting the flight characteristics. Ya scallywag! Time for some real flight tests. [Rocket Pic]

It be a pretty nice day for launchin' rockets. Avast! Begad! Moderately windy, me bucko, but not too bad. Blimey! Aye aye! I was anxious t' try out t' CiCi, me hearties, so it be first in line. Ya scallywag! Avast! I figured the light weight o' t' rocket, combined with t' moderate wind and t' fact that this was t' maiden flight, me bucko, dictated usin' an A8-3. Aye aye! Avast!

It be a good, quick boost, matey, as you can tell from t' blur it gives in this photo, shiver me timbers, matey, even with 400 speed film. In spite what this photo o' t' early flight path might indicate, it was, shiver me timbers, overall, shiver me timbers, a fairly straight boost to, oh, ya bilge rat, maybe 150 feet or so (I didn't measure it). Avast, me proud beauty! Begad! Even though it arced over on its back after burnout, it make a smooth, me bucko, me bucko, controlled transition t' right-side-up glide. Avast, me proud beauty! The glide was ok, but still with a bit o' nose-down attitude, me hearties, and it definitely falls faster than a Deltie. Begad! Avast! It made about 1 3/4 circles before landing. Blimey! . Begad! . with a crack. Ahoy! Uh-oh. Begad!

[Rocket Pic]As you can see from this photo, me hearties, it snapped clean in half on landing. Arrr! Note that although it's photographed here on cement (for clarity), matey, it did land in t' grass when it broke. Begad! Disappointing, but not the end o' t' world. Aye aye! Blimey! 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. Blimey! Avast! This is just soot from t' black powder, not scorchin' o' t' wood. Ya scallywag! Ahoy! A bit dirty, but nay a safety concern. Aye aye! Begad!

Unfortunately, shiver me timbers, t' second flight, under nearly calm wind conditions, was an exact duplicate o' t' first. Ya scallywag! T' A8-3 gave a good, straight boost, with a nice transition t' glide, a decent but slightly too rapid, nose-down descent, and a landin' with a crack. Ahoy! Blimey! Broke clean in half again, this time about 3mm further rearward (CA is strong stuff). Arrr!

Warning! 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. So, prior t' t' third flight, I sanded an airfoil into t' top o' t' canard. Begad! Ya scallywag! I left t' bottom o' t' canard completely flat. Ahoy! I left t' bottom o' t' canard completely flat. T' idea was to have this canard generate more lift, me bucko, shiver me timbers, and thereby lift t' nose in flight, givin' a flatter glide. Blimey! Hand-tossed glides didn't show any visible difference, but I be confident that it would be noticeable at speed. Ahoy! Avast, me proud beauty! DO NOT TRY THIS WITH YOUR MODEL! T' airfoil be much too severe, me bucko, and caused t' model t' arc over under power and plow into the ground at full speed! Ironically, me bucko, t' damage be only slightly worse on this flight, 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, and you want t' try t' airfoil t' canard t' help that situation, start with a very slight airfoil, and perform actual launches before sandin' any further.

Overall, matey, I give t' CiCi a 3 out o' 5 points. Well, blow me down! T' kit itself gets a 4 out o' 5 points, havin' high quality parts, me bucko, but missin' a couple minor pieces. Begad! T' instructions should include trimmin' instructions, me hearties, but were otherwise adequate, shiver me timbers, ya bilge rat, despite their brevity. T' construction gets a ratin' of 4. 5 out o' 5 points bein' simple and straightforward. Avast! T' flights (before the airfoiling, at least), were both excellent, ratin' a 4 out o' 5 points. Blimey! O' course, me hearties, t' big downer was t' recovery, particularly t' landin' damage, matey, which is easily fixed, though nay easily avoided. Well, blow me down! T' recovery gets a 1. 5 out o' 5 points. Begad!

I'll probably repair t' CiCi again when I get a chance. Well, blow me down! Aye aye! If you're looking to buy your first boost glider, shiver me timbers, I'd have t' recommend t' Edmond's Aerospace Deltie. Avast! But, matey, t' CiCi certainly has t' potential t' be a great boost glider, perhaps as your third or fourth boost glider model. Avast, me proud beauty!

  • Edmonds Aerospace CiCi By John Thro

    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 ...

1. My kit came without clay, but had the little tube marking piece. I bought it from Apogee Components over the Internet; a very easy experience with a quick arrival. 2. I too, tried a test glide in the house. I too, saw the nose down attitude. In fact, the third test glide resulted in a break in the same location as shown in the picture above. Having read the above review, I was thinking, Oh no, I bought a bum steer! I reglued the break, and took it to the local MASA launch in Elk River MN the next day anyway thinking Oh well, the failure will be spectacular. Much to my surprise, the thing flew well on both a 1/2A6-2 and an A8-3. I did not try and tinker with it to get a good test glide. I flew it as-is out of the box (plastic). SO, DO NOT TRY TO TRIM THIS GLIDER. FLY IT AS-IS! 3. Some notes on whether to finish this by painting would be appreciated, as well as some warning about not trimming before your fly. I rate this a 4. 5 on build, a 5 on flight and a 5 overall. My 10 year old daughter could do it all by herself if Dad would just get out of the way and let her do it. This review is misleading in that the builder deviated from instructions before he flew it.

The CiCi is a quick build and looks nice. It flies well on A8-3 motors, but Rob, the glider designer, told me to find a big field and put it up on a C motor. Well, I tried a B6-4 first and both wings shredded. And not at the weak points where the rudders(?) were glued to the rear wing, but in the middle of the rear wing. Not pretty! I need to research the cause and try it again. Generally, Edmonds products are easy to build, look good and fly well. The review was solid

Mine came with neither the clay or tube marker, but went together nicely. I flew it six hours after I built it, but could have gone sooner. The CiCi went up in an upside down arc and just when we were about to give it up as a power prang, the ejection charge fired, the rocket performed a loop and righted itself, then headed off for the trees still flying at between 100 and 200'. (The trees are atop a large hill.) It hit near the treetop and bounced it's way down until it got stuck about 15-20' from the ground. After a couple of whacks with a tossed stick it flew the remaining distance to the ground unharmed. Interesting flight. I can't imagine the field that you'd need to fly this one on a C6-5. I'll trim it to glide in a circle next time. Choose your engines carefully for the CiCi. Start at the bottom and work your way up or kiss this one goodbye. It's a heck of a glider.

This was first attempt at a project of this kind. I figured it would be a great way to make use of the plethora of A8-3 motors I had left over from Blast-Off Flight Packs. The build was easy and it is amazing how precisely cut the parts were. The flight of my CiCi was fine, and I didn't have anything break and was pleased to see that an modestly priced kit could perform as well as it did. Before I assembled ANYTHING on the CiCi, I contacted Rob Edmonds regarding the use of paint, sealer, tissue for the wings, etc. He informed me that it is best to build it stock as the instructions show. Hence, that is exactly what I did. Neat little glider and a perfect use for A motors!

My CiCi flies great, except when the ejection charge snaps the fuselage in half. I've had to re-glue it 4-5 times because the ejection just breaks it in half. By now, all the CA has fixed the problem. When it flies right, it really is quite nice.

The CiCi was the star of the show for my neighborhood rocket launch today! Flew multiple times on A8-3, B4-2, and C6-3 on a field about 400 ft. square. B4-2 flights were perfect! The C6-3 flights rocked but were on the edge of being a bit too large for this size field. Recovery was in large graceful circles. [BTW, I tried for this effect by adding a fillet along one side of the fuselage.] No breakage problems though I took the suggestion from the tip below and poked a second hole in the body tube opposite the existing one. Stock construction other than that. Highly recommended!

I built my CiCi in about 12 minutes. The lazer cut parts go together very precisely. 1st flight was on a A8-3. I never thought ANYTHING could fly away, out of sight and into a swamp 1/4 to 1/2 mile away on an A8-3! and on a calm day! I lost it, but returned (in long pants) to find it later that evening. I have now trimmed it to fly in circles!!

I built my CiCi in about 7 minutes, used CA throughout. No problems. I used a center cutout from an estes engine mount(a bt20 sized disc of fiber paper) glued to the inside of the left vertical stab.(for trim weight) I also dusted the model with fluorescent pink paint and then rubbed it down with steel wool for a "stained" color effect with almost no weight. Also added the additional hole for the engine to vent. I did nothing in the way of sanding or shaping. Flew it 4 times in the first outing on A-8-3's, perfect results, nice straight boost,100' circles to the ground. The kids were ecstatic, and I was amazed. GREAT KIT!!!!!
