1. Don’t fly in winds over 7 mph! First-time pilots should get help from an experienced radio control pilot
during first flights.
2. Choose your flying field carefully–grass and soft ground with 600-foot diameter is optimal to fly
and will lengthen the life of the Aerobird Challenger
™
.
3. Remember that holding the right stick full over for too long can cause the Aerobird Challenger to spiral-
dive and crash. At the very first sign of the Aerobird Challenger beginning to spiral down, immediately
release the stick and give the opposite turn control to the spiral, then pull back on the elevator to level
flight and level the wings.
4. Don’t attempt to fly or do maneuvers beyond your flying abilities without seeking the assistance of an
experienced pilot.
5. If you’re gliding with the motor off, allow the Aerobird Challenger more area for turns.
6. Position yourself at your flying field to keep the sun at your back and out of your eyes. Wear sunglasses
on bright days.
7. Keep the Aerobird Challenger upwind, especially on windy days, to prevent it from “flying away”.
The wind is normally stronger at higher altitudes than it is on the ground.
8. Keep your plane in front of you so you don’t have to turn in circles as you fly. Try to avoid flying
directly overhead.
