SERVOS
Because of the size and weight of the Extra 330L, standard servos do not produce enough
torque for high performance aerobatics or 3-D flight. The following are the minimum
torque requirements for this level of performance:
Ailerons:
Flaps:
Elevators:
Rudder:
Throttle:
Choke:
Also, due to the number of high load servos, we strongly urge you to use a good flight pack
of at least 2000 mah or better.
CAUTIONS:
Gas engines, because of the ignition systems, require some special care. The ignition is
capable of producing radio interference that can shorten the range of the radio gear.
To help minimize these problems use the following recommendations: Never use a solid
wire for throttle control, use Nyrod or other plastic nonconductor. Keep all radio gear at
least 12 inches from all ignition components, such as battery, switches, wiring and the unit
itself. If a servo is used to operate the ignition on/off switch, do not mount the switch at the
servo, instead use a piece of Nyrod and a remote switch bracket. Be sure spark plug wires
are shielded and the shield is properly grounded to the engine. Follow the engine
manufactures instructions. Large powerful servos have a higher power consumption rate
than standard servos, for this reason it is important the battery selected be capable of
supplying the required amperage. The switch harness must also be of the heavy-duty type.
A lightweight switch may overheat and fail under high loads.
