How to regain control with transmitter

New to qgc. I have it working with apm 2.8 but I can not find anywhere how to regain control of the quad after I press takeoff. The quad will take off and hover at 10 meters but I have no control with the transmitter. Is there a way to regain control or is it in that mode until I land and arm it with the transmitter. I can press land and it will do so. Am I missing something? or am I having a dumb moment.

Although QGC will sort of work with firmwares that will run on an apm 2.8 it is not supported. That firmware is just too old the run with. You should have gotten an error about that when you connected to the vehicle.
