Hey all,

I've been flying glow and gas airplanes for quite a while and I recently purchased E-Flite's Mini Edge 540 and when it comes to its setup, I'm pretty clueless.
First off, I have E-Flite's 20-Amp Sensorless Brushless ESC and after receiving it I learned that they suggest to use the updated version (the "B" version) as it will handle the 4 servos required for the plane. My question is can I use this ESC without any problems during flight? I plan on pushing this plane to the limit so I want to make sure it will work. I'm also a little foggy on what the difference between the two is...
This may seem like a dumb question, but again I'm clueless about this...I have an 11.1V 2100 mAh 3-cell Li-Po battery. Can I get away with just one battery? Or will I need multiple batteries if I'd like to fly multiple times?
I've also read the 10 page thread on this plane and I was considering going to an outrunner motor... the only thing is I'm clueless as to what to look for.
Well, that's all for now. Any help would be greatly appreciated.

Thanks!
Shane
