Plenty of people started building them but very few flew. What was the problem, anyone?
I bought a set of plans/build licence several years ago, and quickly realised that it was a fairly complex little aircraft with a high component count that had to be built to very exacting standards (more so than normal). At the time I decided that it was beyond my capabilities and patience. I was in touch with a French company that was going to start producing pre-cut and drilled kit components but it came to nought.

I still have the plans if anybody has the urge to rush out and build one. :)

In the world of 'One day...' I'd love to build a Cri-Cri. One day, when I have the time...and the space...and the money. When did you get your plans & what did they cost then? I've heard that they're no longer available from the designer, although I have no information about the veracity of this rumour.

What sort of things did you feel required more than basic sheet metal fabrication skills? Are there items that must be forged, milled or turned? Special tools? I've never even seen plans for a Cri-Cri so I'm a bit in the blind about what's needed.

But to have a Cri-Cri! Imagine the comments taxiing one at Orlando International... :E

I got the plans from M. Colomban many years ago and have no recollection of what I paid although a quick Google suggests the last known price as being €208? I believe you are correct and that plans are no longer available and I further understand that some of the aluminium extrusions and other components are very hard to find.

I was just naive (and very young!) in thinking little aeroplane = little work! No superhuman skills are required although some components do need to be turned and machined. The wing skins are glued to the foam ribs and held in place with a vacuum bag until cured I seem to recall. The tolerances to work too were very strict as you can imagine with a wing area of just 34 square feet it has to be built very accurately. In short I did/do not have the patience for the many hundreds of hours work needed, having studied the 42 sheets of blueprints and read the construction manuals I have the utmost admiration for anybody who builds their own aircraft.

Also be aware that the American version (Cricket?) might be modified in an unsatisfactory way.

This is G-SHOG
 
I found someone brave enough to pose in front of the Cri Cri as a size reference. I'm not sure it was such a good choice of comparison.

I offered to buy the aeroplane off of the owner, on the spot, but he looked as though he wanted to own it for another 100 years. :)

“Will the Cri-Cri fly at all on one engine?”

There are a variety of engines used, but I have seen one flown on one engine as part of a display in France and it was doing aerobatics…

It has a reputation of being hard to build, but Dyn Aero do sell some bits for them. His next plan build aircraft, the MC100 Banbi was also quite a challenge, until it was redesigned into the MCR01 by Mr C Robin. Mine took me 1800 hours, but I did get there in the end!

I'm sure G-SHOG was part of a display where it landed on top of a speeding Shogun (presumably hence the reg).

Have rummage briefly through youtube but cant find owt.

WellI was close: it was the takeoff

When the Airbus A380 comes to Oshkosh this summer, apparently one of the pilots is bringing his Cri-Cri along too, as cargo.....

In an overhead locker? Or the baggage hold?

I wanna Cri-Cri.! I wanna Cri-Cri! <stomp>



"Wonder what it costs to build one?" muses a little voice in my head.

The first time I saw a Cri-Cri in action at Biggin Hill, My first thought was "I'd like an hour in that!" As for cost....Pass.

There is a Yahoo Group which discusses the Cricri in great detail. It is more for the actual builders rather than the "dreamers" so if you go there as a "dreamer", please read the info (all the questions you will have have been asked before , so search) but let the builders get on with their serious discussions. Here is the site CriCri : CriCri.
Michael Columban still sells plan sets for the aircraft. However, due to a past litigation problem, he will not sell them to anyone from the USA. As you will see at the Yahoo site, it is strongly recommended not to proceed with the Heintz Cricket (US version) which allegedly has some design modifications which are "unsafe" and have lead to some accidents.
The Cricri is certainly a unique aircraft.

Hello JamesTigris,

I just want to ask if, Do you have the CRICRI building manual?
I am planning to build one.

tacpot 6th Jul 2018 19:59

I've seen that there is now an electric Cri-Cri. This could be a factor in a resurgence in interest in the design as the availability of the JPX engines was one of the factors holding it back. The unusual materials used in construction and the lack of support from Colomban to select alternatives still make it difficult to see how any new ones will be built

Jan Olieslagers 6th Jul 2018 20:13

Unfortunately, an electric-powered Cri-Cri suffered a bad accident, killing a person quite well-known in tinkering circles in a rather horrible way. I know of no proof that either the aeroplane design or the particular electric installation were to blame, still there was very little news after that; if any at all.

Very sad, but why would an electric aircraft catch fire?

Possibly because they were high powered Li-ion batteries and short circuited in the accident.
Near here at an industrial estate at Royan, a company built an electric Cr-Cri , but in carbon fibre. Then went on to build an electric tandem twin trainer which had an endurance of 45 min. Looked good and tested well. But AirBus pulled the funding, so not going into production.
IIRR, the Cri-Cri had four motors, two on each side, back to back.
