While flying GSPro mission with M200, I sometime loose RC connection (remote controller strength signal turns yellow).  At times the same mission is completed without any signal loss.  I have a Parrot Sequoia sensor attached to the drone (sunshine sensor on top).  Any ideas why this might be happening?
