I have to disagree with the use of this motor for anything larger than about 1/2A size -- they are rated at 11 amps for 60 sec., and up to about 125 watts. I doubt you'll get any kind of flight capability for anything larger than 150 - 175 sq. in. and weight of up to maybe 12 oz.
If you want to fly something the size of a Jr. Ringmaster or Jr. Flightstreak, you will need 225+ watts and the 2217/xx series of motors, in my experience. You can get a real cheap one - like a BP 2217/6 for about $20 - it will handle 20-25 amps on 3 cells and turn a 8-4 at over 11000 RPM.
For a Bearclaw, Skyray, etc., something over 350 watts will be needed.
I've been using a 2212/6 (BP or Suppo but the same numbering system as Axi) at about 10 amps on 2 cells - turns a 6-6 at over 13000 RPM. This on a 30" span, almost 200 sq. in. 1/2A size profile. This one has a Kv of 2250. For 3 cells, you could try whatever model has a Kv in the 1500-1800 range on something in the same range. On a light plane (about 10 oz.) this will do the beginner's pattern on 42' lines, but only just. In any kind of wind, probably 35' lines would be the max for comfort.
Just another opinion --
<Hobby Lobby no longer has spec's in their on-line catalog for any of the brushless motors, but here is a blurb from the review they reference:>
2212/26
This one would be a 7 to 8-cell nickel or 2S
Li-Poly direct replacement for most of the
geared 300 drives out there, in planes like the
GWS warbirds or Mountain Models or Stevens
AeroModel ships, using the same batteries and
props (9 to 11-inch diameter) as you would use
for the 300s. On 3S Li-Polys or on 10 nickel
cells, it is comfortable with 8 and 9-inch props,
or the 10x4.7, and at power levels up to 125+
watts. Planes like the foam Potensky Christen
Eagle from Hobby Lobby would be a good
application for this one on 3S Li-Polys.
