Error When Making Waypoints In Mission Planners

I want to try to make a waypoint mission in the mission planner, but I get an error, is there anyone who can help solve this problem?

Big age gap is not only bad in marriages but also causing problems with Arducopter and Mission Planner. :slight_smile: You should get a Mission Planner from the historical period which matches you flight controller firmware (which is around five years old).
You can access old releases of Mission Planner from here : a version around 1.3.3x will do.
