I'm just about to buy some bits and pieces for my Sky 120 build and was wondering about rx. battery size. As this is my first large plane, what sort of mAh are we looking at? Obviously with the larger surface area of the control surfaces, servos will work harder, but would a 6v, 2000/2400 mAh be sufficient?
RC gear is Spektrum 8000 rx, and will be with 6020 servos (6 off) when I press the "buy" button.

Thanks
Richard
