Notes:
1
These signals should be run in a shielded cable along with the appropriate ground signal. Ground the cable
shield at the EZ Pilot end and to a servo mounting screw at the servo end of the shield.
2.
Power ground wiring should originate at the airframe ground point.
3.
The circuit breaker used to provide power for these inputs should be sized according to the size of the wire
. being used to provide power to the circuit. For 24 gauge wire, a 3 amp circuit breaker/fuse is appropriate.
