Well the Dual inline Axi 5330 is pretty big. I'm not sure about others though.
There are still massive three-phase motors used in industrial applications that are bigger than any of our model motors.

Check out the Plettenberg Predator outrunner. They claim up to 33 LB aircraft.
I saw it at Toledo this year. It's not as heavy as it looks.
I believe the rep said it is capable of up to 2500 watts. If I am wrong, ignore me, my wife does.

Check out the "BAM" motor from www.neumotors.com The 2215/2Y version is a 6kW motor that turns can turn a 30/20 prop. A larger version is in the works for this summer

Holy smokes. 5500 Watts peak and motor weights 25 oz. Crazy. Now we're talking. I love Neu motors. The 2215/1Y is rated at 145 amps. I'm in love.

And the Predator Outrunner: "Composite ARF Yak 55, at an all up weight of 29 lbs, with 14S3P Kokam 9600mAh, pulling 220Amps peak. Prop was a RASA 26 x 12."

220 Amps peak!!! I don't think I've ever even seen an ESC that is rated at 220 Amp bursts. Is there such a thing?

Other big motors include the actro monster, the astro 120, and the hacker A60 L 's. These range from 2500 to 5000 watts. Lots of choices if you decide to get into the big birds.

Just for fun, I looked up a few motors that are mentioned in this thread:

pletti predator: up to 10,000 watts! Weighs 55 oz, up to 30" props. Direct drive. Price?

Neu BAM. Up to 5500 watts, up to 30" props, 33 oz. with gearbox. Cost around $750.

Astro 120: 32 oz, up to 20" props direct, $299

Those BIG Lehner are on sale at finedesignrc.com, I bought a 2240-10D from them and like the Lehner, just smooth and innovative with changable kV feature, eg mine have a kv~1500, change the winding from Delta to Wye could turn it to kv=1500x1,7=2250.
They are 2 poles motor like hackers, I 'feel' those 2 poles motor more smooth in idle , and that makes them for good sport motors.(this may not be true scientifically,but just with my experience ).
Take a look at them with no lost anyway.

Which Lehner would you pick to push a 8lb plane on a 6s??

lehner have a calculator on their site... it looks for a few parameters like revs and amps etc. and then suggests a motor for you...

something like a 1930 series (230g) should give you 800 watts comfortably and efficiently with plenty to spare if pushed

Milt,

I'm waiting for the Komodo "KH-5030 Outrunner Motor Kit" so I can get 2KW for under $40.
