Flight attention
Do not fly at any place where another same-frequency model is being operated.
Taking off:
Always take off toward the wind.
When launch F9F-8 COUGAR by hands, maximize the power (include the
micro-adjuster) and run several meters, then throw the F9F-8 COUGAR horizontally.
When launch F9F-8 COUGAR on the ground, maximize the power and let F9F-8
COUGAR accelerate in direction of the wind and keep it running straightly, after it run
more than 60 feet, then pull the elevator joy stick, and it will take off.
Flight:
To keep F9F-8 COUGAR flying only need 50% of the maximum power, it is a good idea
to fly with power for a while and glide for a while. In this way you can prolong the
maximum flight time and familiarize yourself with landing approaches.
Landing:
Before landing, switch off the power, fly along with the wind, and when F9F-8 COUGAR
flies near to the ground, then pull the elevator joystick and F9F-8 COUGAR will landing
gently. With more practice, then you could control the model easily.
