the thing is actually bigger than the PCM receivers.....and that hump sticking out is ridiculous
You're wrong. It's actually much smaller than the PCM RX, it's the size of the HRS receiver, which has always been considered quite small. I don't know how you guys can think this RX is too big.
And that hump is the second antenna, part of the reason why this system has been flawless - unlike Spektrum.
