Small Gyroscope Sensor Recommendation

Hello,

I need a good, sensitive, gyroscope for a project I am working on.

The project is a self-balancing reaction wheel, for this I need an accelerometer and a gyroscope.

I currently have an adxl345 accelerometer which works well.

Is it better that I acquire a separate accelerometer and gyroscope to conserve space and weight?

Or should I just get a good gyroscope and put that next to the accelerometer?

If yes to either, then which one?

Thanks.

Many people use the MPU6050, which has both in one small package. But there are lots of other, more modern options. Pololu has a good collection.

Thanks
