The Fourmost Remote Fuel Control Valve is a device that allows the modeler to have complete control of his needle valve setting throughout the models operation.
The modeler can adjust the needle valve setting midflight, maintaining the optimum RPM for various flight and engine conditions.
When the model is on the ground the Remote Fuel Control Valve enables the modeler to adjust the needle valve setting, while keeping hands clear of propellers and other moving parts of the engine. The Remote Valve also provides a shutoff function. This may be activated while airborne or while on the ground, ensuring safe engine operation.
