Get help to hand launch your aircraft so you can
concentrate on ying. If you must hand launch the
aircraft alone, hold the model in your dominant hand
and the transmitter in your other hand.
1. Face into the wind and apply 1/2 (50%) throttle.
2. Hold the plane horizontal and launch straight and
level into the wind.
3. The aircraft will climb under full throttle (100%).
4. Reduce to 50% throttle once the plane is at a
safe altitude (50-75 feet) to level out.
5. Use the throttle to control altitude.
To turn the aircraft make small controlled movements with the right stick.
For a right hand turn:
1. Move the right stick slowly to the right.
2. Once the turn begins, add in a little throttle to maintain
altitude.
3. Use gentle stick movements to continue the turn to the right.
• If the turn is too wide, add more right stick.
• If the turn is too tight, add less right stick.
4. To stop the turn, gently release the right stick and lower the throttle to maintain level ight.
Try to nish the turn at the same altitude it was started from.
Wind 0–5 mph
(0–8 km/h)
For a left hand turn, follow steps above, moving the stick to the left.
