I think about installing additional 915MHz receiver into drone which has 2.4GHz receiver. I want to keep controls when 2.4GHz is jammed or drone flied too far (or behind large obstacle).
But opposite team will try to hack and steal our drone during the flight, so, it's a bit dangerous to have two simultaneously working receivers when we use only one.
Does this idea have a sence? Is it possible to add reserve communication line to drone with keeping safety (maybe receivers can be switched in some way)?
