Notes: Due To The High-Power Vtx Onboard, The Temperature Of The Aio Flight Controller Will Be Relatively High In The Standby State, And The Camera Signal May Be Lost After A Couple Of Minutes Standby. This Is A Normal Phenomenon, Please Don’T Worry. We Strongly Recommend Using A Fan To Cool Down When Setting Up The Flight Control. Please Make Sure The Vtx Antenna Was Plugged Before Power For The Aio Flight Controller.
