MotionRC is the best!
I received (in record time) my new Admiral 4-Cell, 4,000mAH, 40C discharge, Lithium Polymer pack and it is practically identical in size dimensions as the Turnigy 4-Cell, 3300mAH, 30C, Lithium Polymer pack that I am flying my Corsair presently.
Best, the new Admiral came with the T-Connector already soldered and can't wait to see the difference with the 40C discharge rating.
I had plans to change out the MAS 3-Blade Propeller and replace it with an XOAR Electric 2-Blade, 13 X 8 wood propeller but, want to observed what performance increase, if any, the new Admiral Battery pack allows.
