So the other day i was flying my karma around a waterfall and had been doing great but wanted to get a shot flying over the stream up over the water fall. so obviously getting a little too confident in my piloting abilities i start my maneuver and there is a small tree branch that pops into frame and run square into it and my drone falls into the water... well i retrieve it and get the battery out of it as quick as i can. i also let it dry for a week before attempting to power it up again. well when the i attempted to power up again there is seemingly no power going to the gimbal but when the gimbal is attached to the karma grip it powers up. i have not attempted to contact go pro yet but was wondering if anyone had ideas as to what my issue is there is no visible damage on the drone.
