The three secrets to hand launching the Autel Drone from a boat are:
1 Make sure your boat is not moving because the drone wants to go straight up and so will correct for any motion losing altitude which is bad.
2. Make sure you press the stick straight up for launch. If you are off only a little the drone is trying to rotate and that will cause the drone to drop which is not good.
3. Wait much longer than you think before letting go of the drone. It’s a mistake to let it go when it feels weightless. Wait till it is really pulling and the props up to full speed.
