Although you're using the recommendations from greatplanes things can still go wrong. The only way to know for sure is with a wattmeter, or at least a Multimeter capable of measuring amperage equal to or greater than the expected current draw of your plane.

If you don't mind, could you list again everything you have?

Plane:
Motor: (please indicate maximum allowed current draw just in case we can't find it on the web)
ESC: (please indicate maximum allowed current)
Prop: (size and pitch, manufacturer, if known, and type of prop, ie; Slow Fly, Direct Drive, Thin Electric, etc.)
Battery: (volts or number of cells, capacity in mAh, "C" rating)

Sorry to ask for this information again, but it will be a great help to have all the information in one place rather than having to search the entire thread to put it all together.

Thanks
