[suggestion] Add isolated Up/Down control buttons and auto-balance the flexbot

[liubenyuan]

Hi,

Could I add isolated Up/Down buttons, so that the flexbot can auto-adjust the balance of the plane ?

I find my flexbot has fixed bias to north-east (2'o clock), is there any fixed to this ?

In fact, there are hidden Up/Down buttons, double click on right sceen take a small step up, double click on left sceen will take a small step down.

@i find my flexbot has fixed bias to north-east (2'o clock), is there any fixed to this ?
The Mag sensor should be calibrated.
