Problem Solving
Take-off:
1. Face into the wind, hold the plane horizontally and launch with a pushing motion.
2. Extend transmitter antenna all the way and check plane responds properly to transmitter
signal.
o
3. After launching,Climb 10-20 at full throttle. If plane doesn't climb accordingly, adjust
elevator control. After reaching an altitude of about 40m, begin making circular circuits with
the plane. You can also take off from the ground, gradually move the throttle stick to full
power, keep the plane straight by adding rudder stick when necessary.
Once plane is at full power into wind and has sufficient air speed gradually add a little
elevator until plane slowly lifts off the ground. Be careful not to over control the plane, just
keep steady and straight and climb to a safe height. At this point you should start to make
circular climbs and then into level flight.
Flight:
1. The plane should fly level at around 50% of full throttle.
2. The flight time will be prolonged if you allow the plane to sometimes glide at a safe altitude.
Landing:
When the battery runs low, the auto-cut relay may stop the propeller from rotating or you
should place the throttle to minimum. When the propeller stops rotating, decide your landing
route based on wind direction and landing area. Turn wide into wind. From altitude of about
1m use the elevator to land the plane horizontally, these ensure a safe landing.
