Hobby King has come out with 2 new multicopter motors in the 9014(!) size. One is 105kV, the other 135kV. With 385g, they are surely on the heavy side, but they are designed for 6S with a max current of 40A. According to the description, they were made for 26" props.
Surely nothing for your everyday sport quad, but now there's finally motors available which would allow building really big quads (MD4-1000 class and bigger) with reasonable air times.

Gary McCry maybe this can help...cw and ccw...tri blades too also remove 2 from 4blade and you are ready to go...any size is posible and onc you buy mounting plate wood props are cheap

similar if not the same.. http://rctigermotor.com/show.php?contentid=210
but where the hell are we to buy 26" props that aren't crazy expensive
Gary, when you move into the 24" and larger size of propellers you in "big boy" territory where you usually have to drill you own holes to match the motor your using (2 or 4 hole pattern). It's not that hard, just make a cardboard template using the center hole for referencing and take your time when drilling CF (don't apply to much pressure to the drill).
If anybody finds a not wood 24" or 26" prop actually made to fit these motors using the mounting plate rather than a through bolt prop adapter I'd like to know about it.
The biggest flat mount CF props I could find were 17"
Xoar lists wood props any size up to 40" but they need a conventional through bolt type prop adapter.
That's one way to do it. Cool
@Lanmark: I used to work with a ROV and there was 320volt DC in the cable from the remote to the ROV. Then a voltage divider in the ROV down to 24 volt for loads. 320volt don't require a thick cord.
I saw this on product's comments section

that would be one seriously thick extension cord.. especially since the cables going to that tiger motor already look like garden hoses.. lets see.. where can I find a 250A per motor extension cord :)
Propellers are hard to find for these, there are wood ones, but they would need a prop adapter.
And the 12 1/2 horsepower motor from RCTiger could power an ultralight.
Four of them could probably power a 1 man quadcopter although you'd probably need to run it from an extension cord.
Hmm great idea for a carnival ride - - well maybe not.
