I really do not see any reason why I should have the MinimOSD on the plane/copter, if I use 433MHz telemetry radios.
Can't I just connect the 5V, GND, RX to the ground based 3DR Radio, and feed the MinimOSD the data on the ground, getting a clearer OSD, that will keep displaying even when the 5.8GHz video link goes down ? For telemetry, I do not need extremely fast updates. A couple updates per second is probably acceptable.
Doing this, I wonder if I can have multiple 3DR radios listening to the same plane radio ? I.e one for my MinimOSD / FPV and another for a ground station ? Or would I have to split the signal from a single 3DR radio on the ground ?
