I'm getting a Extreme Flight extra 78" and i'm new to the whole powerbox scene. I've noticed that everyone flying bigger planes use some sort of powerbox and have decided to purchase one myself. I understand the principal of powerboxes and all of the upsides, but need a little information on compatibility with my transmitter the Multiplex SX. Do i need some separate parts to get telemetry on my transmitter? Is Powerbox Evolution the best product for me with this transmitter?
