Connect the RPM sensor and thermocouple on its
respective sockets, in the orientation that is shown in the

be extended using good quality servo extensions.
Airspeed (pitot) sensor, if used, must be connected as shown in the
picture, at the side of the data terminal connection.
About solenoid valves, please note that they should be of the same
rated voltage as the battery and consume less than 0,5A.

The last two sockets are used
for the connection of the
solenoid valves. Bottom position

solenoid, and the upper position
