At what frequency are you sampling the accelerometer output?

What is the frequency of the mechanical noise?

For now I sampling the data at 200Hz. It depends on me.
The mechanical frequency is around 60Hz if I'm not mistaken (at half of throttle).

In that case you could damp it in software, if you like, by averaging the samples over a short interval, for example the period of the noise or some multiple of it. Given that the natural frequency at which your system responds to your control is presumably much, much lower than 60Hz, you can probably afford to average over a much longer period.
