I bought the DJI Avata Explorer Combo as well as the DJI FPV controller 2 and succesfully linked them together. Once armed, I am able to control the throttle just enough to get some lift in the DJI avata but as soon as I push the throttle stick too high (about 10% up or more) the DJI avata goes full throttle and I am no longer able to control it. When I push down on the stick there is no immediate respone. I need to keep pushing down for about 5 seconds, then the drone shuts off its motors completely.
I tried it out in both Normal and Sport mode and have the exact same behaviour.

Hello there, sorry to hear that. Could you please provide some related video for us to futher check it for you? Thank you.
