Okay, DJI Digital System is a very good FPV system. More range than their analogue counterparts. This controller is designed for use with DJI/Caddx Air Pods and cannot be used with the new DJI FPV Complete Drone System. Now I know DJI is money hungry, but limit the number of controllers you need in your digital FPV world. With the "1" controller I control 20 models stored in my analog Flysky controller. God, DJI could do the same. It's a bit of a chore for me to reach out every time you want to launch another digital drone model. Hence 4 stars, DJI failed when they could turn on the screen and maybe add at least 5 memory savings per controller or save money on the screen and use 5 buttons for your saved states. While I think the digital system is more comfortable to fly, my analog system lines up faster from the ground to the air compared to DJI WAYYYY's digital system. I love the included 4920mAh battery that takes forever to charge, so don't let it drop below 50% to speed up the charge rate. I will not give up my analogue system, but will only buy DJI/Caddx systems from now on.
