Would the 12L be ok on 8s and a smaller prop? The only reason I want to get the 12L is because it's $20 cheaper as an add on. Should I just eat the $20 and buy the 14L? This will be my biggest plane to date. Largest now is a 59" slick. Anybody have a link or just tell me how to go about setting up the cc bec pro with receiver and do I use a separate liFe pack to power reciever and servos? If so what cell count and mAh? Sorry for all the questions I just want to make sure I get all this right being this will be my first big plane and I've always used the internal bec to power everything on all my other planes. Ok I'll go read the 71" slick thread now to see how people set there's up.
Just my $0.02 but I would recommend looking into the Motrofly 4325-310. I have the 280kV motor on my 71" Slick and it is ridiculous. I'm running a CC Ice 100A, Xoar 20x8 and a separate LiFe Rx pack.
As for the Rx/servo power you can either use the internal BEC or a separate Rx pack. If you use a Rx pack you will have to disable the ESC internal BEC by cutting or pulling out the middle red wire. One tip is to plug it into an extension and cut the middle wire on that so you aren't messing w/ the ESC wires.
I personally like using the separate Rx pack because that way if the flight batteries eject or destroy themselves you can at least have power to glide the plane in. For reference I use an 1800mAH LiFe in my Slick and I take out roughly 80-90mAH per 8:30 min flight.
