What causes shaking?

[EZ1]

I alway monitor the temps, etc. That's why I can't understand why the shaking starts. Usually, I get a message in red when something happens to the engine, but I'm not getting that. It is also strange to me that it happens in such totally different airplanes.

Yes this happens to everyone..the shaking isn't enough damage for a red warning in the chat menu. You are running too hot, or too high RPM.

There's nothing else to say about this..you are killing your engine...when you reduce throttle all the way the shaking will stop..this is how you know you jacked up the engine and its not a bug! Try it

I didn't think it was a bug, I just wanted to know what I may have done wrong. Thanks for all the responses.

I think there are 3 main things you have to consider to avoid that: mixture setting, water radiator and oil radiator. In 109 E4, for example, ( automatic prop pitch ) with both radiators open is enough to avoid shaken.
Check also your prop pitch if manual. It can cause you to over rpm the engine when diving at high speed.

If your engine shakes it some thing you've done or not. High revs and/or temp. Try getting used to lower your revs when cruising and always keep a close eye on temps. Cut the throttle befor diving if you don't have time to set the prop, it only takes seconds to blow the engine in a dive.
