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.

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....

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!

FAR Part 103:

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...

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...

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...

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:
