I bought one of these to find out if it would be enough to power my scratchbuilt Airbus A340-600 project with and was very pleased with what I received. The fan arrived perfectly balanced and the readings I got from my test stand were only slightly less than the listed specs. I suspect that proper ducting will close the gap.

On a 6s 25c 5,000 mAh pack and a K-Force 100A ESC I got the following:
Peak thrust: 5.5 pounds
Maximum sustained thrust: 5 pounds
Peak Current: 86.5 Amps
Peak Wattage: 1821 Watts
Efflux velocity: 118 mph

I don't know the max RPM yet, but I will post what I get as soon as I get the chance. In short, I would recommend this fan to anyone looking for a solid all-around 90mm unit at a bargain price.
