Denis Watkins Posted January 17, 2021 Share Posted January 17, 2021 Looks like a new carb and modified ignition, Quote: O.S. GF30 II Petrol with F-6040 Silencer (L-OS3A010) There are many attractive airplanes for 4 stroke 120/150 size glow engine in the market. GF30II perfectly fits airplanes in this category. The new carburetor 70T is designed for easy adjustment and stability. IG-07 ignitor 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. A long awaited radial mount is released at the same time as an optional part. Just spotted New Pump too: Quote The new pump PD-09 supplies fuel consistently regardless of the orientation of an airplane Edited By Denis Watkins on 17/01/2021 18:48:25 Quote Link to comment Share on other sites More sharing options...

Frank Skilbeck Posted January 17, 2021 Share Posted January 17, 2021 Practical rpm range 2,500 to 18,000 rpm, that should sound good, Quote Link to comment Share on other sites More sharing options...

Practical rpm range !! 9000 it should be, but it is the torque that tells all Quote Link to comment Share on other sites More sharing options...
