This is not speculation - it is based on experience. The added ounce of a little 2cell lipo does not have a noticible effect on performance of these planes.
BTW, I will be at SEFF and will bring a Pogo, Little Toni, and Outrageous.
Look forward to seeing you there.
This completely ignores the fact that a separate BEC http://www.castlecreations.com/products/ccbec.html
will NOT be affected by an ESC failure.
Not to mention that with your 2 cell lipo scenario, if you are not running Spektrum you still need a regulator!
