Again one I ordered from GiantCod instead of the chinese located HobbyKing: http://www.giantcod.co.uk/22176t-250w-1500kv-brushless-outrunner-motor-p-405612.html. I can buy these brushless motors from my local hobbyshop also.
Some websites list it as an 8x4 prop on 3s and 9x5 prop on 2s. I did some testing with my watt meter but this way you can't get it much above the recommended 22A on full throttle. I don't fly full throttle all the time anyway so I would suggest using the 9x5 prop on 3s. This way you can go over the recommended 22A without hitting the max of 28A and cruise around on a good efficiency.
When I received the motor it didn't look like the first picture that originally was displayed on the product page. Instead it looks like the motor on the new picture on the website:
No more of these motors for me for sure. I just noticed the NTM motors from hobbyking were in stock. Or at least some of them. I went ahead and ordered a 450 watt version, just to check it out. If that one runs wel those will be my next motor also.
