Throttle manual control

To simplify the startup of models with combustion engines, we've designed a small portable device that connects to the receiver through the manual throttle control port.

When plugged in, the device temporarily overrides the transmitter’s signal and takes control of the throttle servo via its integrated sliding potentiometer, giving the pilot full authority during engine start‑up. A green LED on the controller and the receiver’s LED both light up to indicate that manual mode is active. Once the engine is running, simply unplug the device and the receiver will automatically resume listening to the transmitter.

The manual controller will adjust the throttle channel’s travel according to the endpoints defined for that channel in your model, protecting the servo from excessive mechanical movements that could damage it.

For aircraft with enclosed fuselages where the receiver is hard to reach, you can use a servo extension cable for the manual controller—keep one end attached to the receiver and secure the other at an easily accessible point on the fuselage. Make sure the extension is firmly fastened to prevent tugging during flight and observe correct polarity when connecting the starter.

Do not connect the manual controller to any pin other than its designated one. Observe the polarity marked on the receiver’s label. If after connecting it you notice the starter’s LED dimming and the throttle channel fails to respond when you operate it, the polarity is likely reversed.

Do not use the manual controller to attempt flying with it fixed at a constant throttle setting inside the aircraft. Although it might theoretically maintain a power level, it was not designed as an automatic flight system, and using it for this purpose may result in unpredictable behavior, loss of control, or even damage to the model.
