It does look good for the price,the problem is that it is a fairly hot wind,3000kv is getting up there.I run an ebay special 3000kv on a Slinger wing with a 5.2x5.2 prop,and the amps on that are about as high as I want to take it on my flightpower 20C 2100 3S.I will check the draw later if you like,but I know its high.A 6 inch prop on it would stress out you batteries and esc.Even though the new batteries claim 20c,I would take that with a fairly large grain of salt.
My favourite motor on 3S on the Stryker is the Align 400L @2500kv.It draws nearly 30 amps on a 6x4,which is about the minimum size prop that you want on a Stryker.The Mega 16/15/4 is a 2200kv motor from memory,so you can prop up a bit,or go 4S with less pitch.The 3000kv motor is a bit too hot to run 4S,unless you are talking ducted fan,or are using really small props.
My advice is to get something in the range of 1800 to 2500kv,and use your prop selection to keep your amps below 30 or thereabouts.Whatever motor you choose,at 30amps x 11 volts +330watts...which should widen your eyes somewhat,it sure did for me the first time I tried it...
Strykers are good in that you can generally run higher amps through your motor than recommended due to the airflow through the motor...the same holds true for the esc,keep her cool,and you can push them a bit.I would also go for a 45amp esc if its not too much dearer.Keep an eye for the future..
Hope this helps,
