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!

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.

Thanks,

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
