Hello, I have been getting extremely into drones over the past few years. I have become a pretty decent pilot and I feel that I am ready for an upgrade. I bought an Open-Source Cheerson CX-20 to "build" to understand more about how UAVs work (not just how to fly them). I've went ahead and done some normal upgrades like a gimbal, landing gear, and props but now I need some help. I would like to get a bigger battery to be able to support the added weight but I have no idea what to get? I am also looking to put telemetry into the drone and not quite sure what all I need.
I would really appreciate any advice or input!
