User Manual

After you have completed all of your radio setup, take the model outside and install your propeller. Test
run your power system in a safe manner. Recommended power level for the Extra is 350-440 watts.
NOTE: Small brushless motors typically have aluminum prop adaptors with aluminum screws threads.
These threads are easily stripped or broken. DO NOT apply too much torque when tightening your
prop. A wrench is not necessary, it applies too much torque. We prefer a nut-driver or pliers.
Be sure to check the motor manufacturer’s recommendations for help in selecting a prop.
Recommended Equipment for the 47” Extra:
Motor: Omega 103g1030KV (12 x 6 prop)
Omega 130g 870KV (14 x 7 prop)

Special note about servo arms:
3DHS manufactures longer servo arms for the Hitec HS-65 servo. Some transmitter setups require
longer servo arms to achieve full 3D throw.
