Here is how to get easy stunt points: 1. Go to Panau International Airport. 2. Drive any car (No Bikes) into the Airport. 3. Hook your car onto any moving plane (stunt jump recommended). 4. Keep the same speed as the plane until take off or else the grappling hook will come off 5. When the plane takes off you will dangle in the air and the stunt points will come flying in, as long as you don't let go.
When you find a billboard that features the face of the dictator Baby Panay use the grappling hook to position Rico directly over his face. If you then press 'Action' Rico will draw glasses and a mustache over the face.
