Move the throttle stick to the bottom position and then switch on the transmitter.
Connect the battery pack to ESC. A special tone like "123" means the power supply is OK.
Several "beep–" tones should be emitted to present the amount of lithium battery cells.
When the self–test is finished, a long "beep–" tone should be emitted.
Slowly move the throttle stick up. The prop should start rotating clockwise (looking from the cockpit of the plane). If it spins in the opposite direction, pull the throttle stick back, disconnect the flight battery and swap any two of the three cables between the motor and the ESC. Then re-check again.
