O.S. GF30 II Petrol with F-6040 Silencer

There are many attractive air planes for 4 stroke 120/150 size glow engines available. GF30II perfectly fits this aircraft category. The new carburettor 70T is designed for easy adjustment and stability. IG-07 igniter has applied a new plug cap for easy fit to a spark plug. The plug cap moves freely on the spark plug so that you can decide the best angle of it depending on layout. The F-6040 silencer muffles the noises and creates typical 4-stroke exhaust sound. Linear throttle response is suitable for both scale and aerobatic airplanes.

F-6020 silencer, IF-07 igniter and spark plug ME-8 are included as standard accessories.

The new pump PD-09 supplies fuel consistently regardless of the orientation of an air plane. (The carburettor is removed to show the pump.)

The carburettor has a built-in regulator. The metering needle and the rotor are modified for easier adjustment and stability.
