I am using my first YS 140 FZ on my pattern plane.I bought it used, it seems to have plenty of power.I am using a 16 x 10 prop and running power master pattern blend 25%.My problem is when I first start the engine I set the throttle trim so the engine idles good, but after I take off and fly a few minutes and come in for a landing the idle is quite fast making landing difficult.Any suggestions? Thanks

The idle is probably too lean, and the regulator may also be. Try re-setting them one at a time.

Thanks for the reply.although I'm not very familar with this engine.Do you know of a link that provides the info on how to set the idle on this engine?
