RE: SD 10G or what?
Well I set up my Katana with the 10G. Everything was easy to find and easy to set. I think it is easier than my 9C. I have the reciever plugged into a Smartfly Power expander pro. With 9 servos that made it real easy to plug it all in. 2 5200mah lipos into 2 regs right to the power expander.
I was using 2 72mhz recievers to handle all the servos before.
