Mission controlled servo output.
I have been through this experience. The plane takes off ready for the mission to deliver a parcel. A servo output is programmed to release the payload at a given destination. Therefore the SERVOn_FUNCTION is set to 0. Plane is in the air and suddenly there is no need any longer for the delivery. So the plane flies back without ever reaching the drop zone. And now what. The parcel below the planes´ belly is a problem for the plane to land. Here is my point. Is there a way without a ground station to activate a servo dedicated to the planned mission? At the moment if servo function is 0, then the pilot can not activate it which is logical. But my experience tells me it would be handy if it could be operated from the TX too.
As it is now I had to land the plane with the parcel fastened to it which resulted in certain damage to the plane, to the parcel and to the release mechanism. Well just curious what ideas are there if there could be any. Maybe there is a way and I do not know it.
