Safety Precautions 

Some common-sense safety precautions are: 

1. Don't connect the motor battery until you have your frequency pin (or other frequency clearance means) and are ready to put the plane on the runway or hand-launch. 

2. Don't turn on the radio system until you are ready for your flight. Turn off the radio system as soon as possible after the flight. 

3. Make sure that the throttle is set to off before turning on your transmitter. Many digital speed controls have a function that won't allow the motor to turn until the throttle stick has been in, or moved to, the low position. Don't make it a habit of testing this function. 

4. Motor-on radio checks must be done with the aid of a helper. 

5. Check the leading edge and tip of your prop for molding flash, if it's not a wood prop. Carefully sand away molding flash with fine sandpaper.
