Hi,

I built Hangar 9 Cub and I installed Evolution 10cc (Gas engine).

So far I did maybe 10 flights and everything went well until my last 3 flight.

I notice, when I was on the final, once I reduced the throttle almost all the way down, the RPM go down and after few seconds the RPM start to increase without me touching the throttle stick?

When the airplane was on the ground I did engine run up and it seems like the phenomena repeating itself. (only when I take Throttle all teh way down)

Anyone have any idea what’s the problem? (is it engine tuning or servo problem? or other)

Please advise.

Regards
Meir
