Frank..all I can tell you is make sure the TX is on and throttle set to idle before you connect the battery or the ESC won't arm. Other than that... :?
Gordo...the CC P10 will work fine. I have the same motor, 3S lipo and gear ratio as TailTwister and I have countless flights on the CC P10. The thing is..according to MotoCalc or whatever, these things will draw like 12 amps. But that's static (plane held stationary and unable to unload) at full throttle. If the plane can move, you can't use full throttle for more than a couple of seconds (plane will just get too far away!) and the amps really drop off if the plane isn't held stationary. Also, the CC P10 is rated for bursts of 15 Amps, and bursts is about all the full throttle you'll ever need.
Couple that to the fact that unless you are running like a TP 3S 2100 pack, your batteries will never deliver 10 amps, anyway. So even though the "numbers" say the CC P10 is too small, real world experience shows that they are a dandy little ESC for this size motor.
But, when I bought a second (actually third, but that's a different story!) ESC I went ahead and got the CC P25. It weighs just a little more, and it was in stock. At the time, the CC P10 was out of stock waiting on the new version.
I think it's gonna be hard to out 3D an E Sledge. The bipes are cool, but I've never flown one. I have the plans, and OverSpray has been wanting one forever, so one of these days..
