The Q500 is older technology but one of the most reliable quadcopters ever built. It is easy to fly and is a stable camera platform. It is not a long distance aircraft and not a speedster. Think B-17.
Most new users have issues with the video feed and which may cause you to loose orientation. If that happens, switch to Home mode until you regain your orientation and then switch back to Angle mode.
Don't take off in Smart mode unless you are 30' away.
Don't launch until you have 13 sats locked on the Q and 8-10 on the ST10.
Remove the camera for your first few flights until you feel comfortable flying and landing.
The Q does not return to the takeoff point. It returns to the controller and will land about 15' away "in the line of flight".
In Smart mode it is automatically in follow me mode. If the controller moves, so does the Q.
The 13" props cause a lot of ground effect when landing so it will bounce below 3' above the ground. If you have trouble landing bring it down to about 12" above the ground, then press and hold the red button until it lands and the motors shut down.
Be prepared to land when the battery voltage reads about 10.7 volts. Don't wait for the low battery warning.
