Range check

Perform the range check as described in the instruction manual of your radio. Ask a friend to hold the transmitter, and walk away holding the model in a regular flight position at the height of your shoulders. The servos have to respond to control inputs (control stick movements) without any glitching or jitter, with the motor off and at full throttle within the range stated by the radio manufacturer. Only prepare to fly if the range check is 100% successful.
