RE: 1/2a texaco
With it being a slower flying type plane, you can get away with a lot of different motors. So a lower KV rating swinging a larger prop.
I have a couple of these [link=http://www.hobbypeople.net/index.php/engines-motors/motors-escs-more-1/brushless-rc-aircraft-motors-1/kms-31-21-brushless-motor-51g-1750kv.html] Budget motor[/link] I am running a GWs orange 10X4.7 prop with a 3s battery. Pulls the 12 ounce plane around very well.
I have this one too. I use a smaller prop to go faster. [link=http://www.hobbypeople.net/index.php/engines-motors/motors-escs-more-1/brushless-rc-aircraft-motors-1/2208-09-brushless-motor-w-hardware.html]motor 2[/link]
So, these will fly it in a slower manner like a powered glider. It will not fly it like a pylon racer. I have used these motors to fly a 60 inch glider. It would not win a speed contest, yet it climbed up nicely and I was able to get some good air time with them.
