Cri-Cri Jet

[RST Engineering]

I'll be a sumbitch, you are right. Here ya go...

Noted French pilot Nicolas Charmont has installed 2 AMT Olympus
turbines in his Cri Cri together with AMT on-board automatic
start-up units and individual EDT's.
The Cri Cri weighs 170 Kg, and should have enhanced
performance withover 36 Kg of thrust available.
The Cri Cri has made his maiden flight in the weekeind of 7-8 March.
Top speed at this flight was 240 km/hour (150 mph). Flying with
only one engine the speed is still 160 km/hour (100mph).

You have never seen that before? That has been posted -many- times before.
Among the favorite debates, is how long the TBO is. Short, I think, in the
almost hundred hour range. Also, they are tremendous fuel hogs. To fly a
medium range, you would not have enough weight left (after fuel) to bring
the pilot along.

It would be an interesting way to log multi and jet time. <g>

(Copied from a different thread - Re: juan missing JJJJJJJJ)

http://www.flight.cz/cricri/english/index.php
This page (bottom) says 63 kg and 75 kg ...for the twin prop versions.

They list "Weight at take-off" as "170 kg," which is... 70 kg (Cri-Cri) +
100 kg (220 lbs for pilot and fuel)

Also this quote: "Whole fuselage weight is about 14 kilograms."

I've seen these numbers confused before. I'm still not 100% sure, but I'm
leaning toward the Cri-Cri having an empty weight of under 200 lbs (90 kg).

Yup, Part 103 legal baby!!! ....well except for the 5 gallon limit on Jet A
....and max speed limit of 55kts/63mph ....<g>

Does the twin-jet Cri-Cri still exist or does someone need to build one
to get the Guiness mistake fixed?

Light Sport Pilot has the restrictions of no turbines and no twins, however,
Part 103 has no such restrictions - but 103 does have the fuel limit of 5
gallons, speed limit of 63 mph and the weight limit of 254 lbs. Safety
equipment can be added above and beyond the 254 limit ...like how about
another 5 gallons of fuel please - for safety!

Guiness World Record smallest jet, only cares about it being a "jet" and
"162 kg" max weight...

Now if you actually want to fly it (apparently Yawn doesn't), then you
can do the FAA paperwork for what classification you desire...

I will contribute to the cause, that has the current record holder
replaced...

Hmmmm at 30 GPH per side, (those little engines use a lot of fuel)
That's about 5 minutes total . Yah outta be able to make some where
around 5,000 to 10,000 feet before flame out. Gas is needed for
climb, but optional for landing.

Wow, that RC/B52 had 8 of them... Seems excessive, without going back to
research it on the manufacters website for a looksee...

I didn't see this line back in the thread so here's some shots of the
twin engine Kri Kri http://www.amtjets.com/gallery_real_plain.html

The larger engine uses 22.5 ounces of fuel per minute, or 1,350 per
hour. That at roughly 6# per gallon that is 14 GPH. (The add said
they had improved efficiency ) Go to http://www.amtjets.com
and select specifications. The fuel consumption is near the bottom
of the chart.

That works out to be 28 per hour or a whole 10 minutes with 5 gallons
on board.

Anyone know of any flying CriCri in the Eastern US?

28 lbs/hour......or am i missing something, but 28 lbs/hour gives you
almost a full hour with 2 pound researves.......I also believe those
fuel flow figures to be at max thrust.......anyone know

When I talked with Nicolas Charmont, he said he can't fly more than 40mn....

There appear to be new contenders:

Yah, but will the landing gear hold together through rotation?

I'm sure zzzoom could roll, loop and spin them...

Well, spin anyway...

Nope. The Cri-cri is _longer_ than the BD-5J. That's why the BD-5J has held
the record for more than 25 years.

I think they need to reconsider by using weight and surface area...

[enewbold]

There's a Yahoo group that has a large number of members who either build or fly the Cri Cri. They probably could tell you how many are flying in the US:

While you're at it, throw size of the country of the designer into it...
sheesh. Knock yourself out.
