Instructions
Spin the rotor with your hands and make sure the rotor rotates evenly and does not wobble.
Turn on the helicopter and watch for vibrations. It is normal for the helicopter to vibrate while the blade is first spooling up. The helicopter should not vibrate a lot once the rotor blade is up to speed.
Slowly increase the power to the rotors until the helicopter lightly hovers above the ground. Allow the helicopter to hover for 30 seconds then turn it off.
Inspect the rotor blades and make sure they are still secure. If the unit is intact, your helicopter's rotor is ready for flight.
