Issues:
1- Image transmission signal weak. Some cases fly 40-50' and gone other times booting up preparing to fly and immediately gone before airborne.

2- Have received several sensor failures.

3- Buzzing noise coming from cam/gimball area. Rotate up/down goes away. Back to forward starts again.

What I've tried:
1- Uninstall/reinstall apps
2- Format & different sd cards
3- Antenna discipline always good
4- IMU/gimbal/compass calibrations
5- Ribbon cable looks good

Above happens on GO & Litchi. Running ARGtech range extender which before these issues would get me out to over 7000'. Towards end of October while on vaca in Florida I put it up, was prompted for firmware update, flew and was fine. Back home after a week or so put up and issues started happening. Currently running up to date apps and firmware. Fly in a very rural area with little to no interference.

Sound like hardware issue of a sudden. IMU? Some posts stalk about inserting battery hard to jolt the circuit board/imu. Anyone else?
