With our J10 customer he wanted to keep the size and more importantly weight to a minimum. He actually started with a PB Mercury but didn't care for the extra weight. The Cortex Pro/dual 7008 setup was the lightest most compact way to go while retaining a dual rx solution. It's a really slick setup. The output channels on the physical PWM ports on the 7008 can be shifted depending on what mode the 7008 is set to. Very cool.
