Spirit can be used as a gyro, stabilisation and rescue system. Wiring to the unit depends on the type of receiver used.

Spirit is pre-programmed to 1520µs servo neutral impulse and 50Hz frequency – please ensure you have the correct servo parameters selected as specified by your servo manufacturer.

Some connectors have non-standard dimensions that could interfere with neighboring connectors after plugging in the unit. As a solution, we recommend replacing these connectors with JR or Futaba type.

Never plug a connector for powering the unit into the SYS or ELE/PIT/AIL positions or you may risk damaging the unit.

1 GYRO

R/C models can take advantage of the full capabilities of the Spirit unit. The Spirit will stabilize the model on all axes and also make it less affected by wind or other unfavorable conditions. When properly set up, flight characteristics should be more stable which will give you the confidence to carry out even the most challenging maneuvers.

Neverthless you can also completely disable the unit' operation so that the control will be same as without the system. Then it can be anytime re-enabled during the flight.

2 SERVO CONNECTION

CH1 – 1st Aileron / Elevon servo

CH2 – Elevator servo

CH3 – 2nd Aileron / Elevon servo

CH4 – Rudder servo

CH0 – 2nd Elevator (optional) servo

AUX2 (AUX for Spirit RS, GTR, W1) – 2nd Rudder (optional) servo

AUX (THR for Spirit RS, GTR, W1) – Throttle Output - ESC or Throttle Servo

Flying wing (Delta) models should use only CH1 and CH3 servo outputs.

3 RECEIVER CONNECTION

Receiver wiring is described at this page: https://manual.spirit-system.com/index.php?title=Wiring

All schematics can be found also at the Spirit Settings PC software - Setup Wizard.

Never plug a connector for powering the unit to SYS or ELE/PIT/AIL ports.

4 CONNECTOR ORIENTATION

4.1 μSpirit

Pin layout of the JST-ZH(R) connectors is different from standard Servo connectors. BROWN (Middle) wire is GND pin. ORANGE wire is SIGNAL pin. RED wire is +5V (BEC voltage). By using JST-Servo cables you can connect a classic Servos and all Spirit peripherals to the μSpirit even with Servo connectors.

4.2 Spirit and Spirit Pro

All cables connected to the unit must be oriented so that the signal wire (Lightest color wire) is closer to the connector pin label, towards the center of the unit. This orients the negative (darkest color wire) toward the edge of the unit.
