Hey all. Just need to know what an oversped engine sounds like when it is doing it or signs you are getting close to this condition. IE:OS .32. Thanks

I know, I know, get a tach! Working on it, just trying to get educated and learn what it would sound like.

When it sounds like it's going to explode or you feel the need to back away.

I agree!
Quantum is 100% correct, there are two speeds that the rotor head can turn. The speed that doesnt sound like its gonna explode and the speed that sounds like its gonna explode. You increase the first speed until it sounds like the second speed then back off a few % points on the throttle.

Tach to verify........

The only people who truly know where the edge lies, are those who have gone over.

Someone on here must have an old engine that they don't care about anymore. Maybe they could make a video so we can see? ...and hear.
