[sps180]

I have about 14 hours on my Challenger 180 and on my last outing I noticed some issue accelerating or running at 4k-5k RPM. Sounded like some type of rate limiter was engaged by the engine. The engine would sound limited for a couple of seconds and then cycle back to normal. At idle or 6k rpm no problems. I checked to see that nothing was caught up in the impeller and it is clear. Anyone have similar issues with their C-180?
