We have been flying with a Master and Slave remote. When the camera operator sets camera mode to Manual and I take off, it immediately switches back to Auto and stair stepping can be seen in the video image as the exposure changes. When this occurs, the operator cannot change the setting back, We tried landing and resetting Manual control a few times, which operated on the ground. Then as soon as the I1 lifts off, it reverts to Auto a few feet off the ground. Any tips?
