Holding Revs when dropping to idle

[Funky]

I'm sorry everyone, I have read about this problem a few times, but I don't remember the answer. I have been searching for about an hour through different threads but I can't come up with an answer.

I'm flying a Titan with OS 50 hyper/MP2. When I land my 50 and bring it down to idle it wants to hold the higher revs for a short period before coming down to idle. If I land quickly and cut my throttle trim to 0, sometimes it will continue to idle for 3-4 seconds before finally settling down and dying. Is my low end needle too rich or too lean? The low end screw is at the halfway point right now.

I would bet your low end is to lean.

Usually means your low end is too lean. Some engine/pipe combos do this no matter what you do though.

I would also check your one-way autorotation bearing. If it has seized, the energy stored in the blades can drag the engine along despite your throttle cut.
