I have a REVO with one bank set to use ATTI and the on board BARO for emergency position hold if I loose VTX.
But, flying around with it on would be pointless.
Other banks are set on ACRO+
Learn to fly so you can fly around in ACRO+ or RATE modes.
I try out an auto level mode from time to time but it's just way to restrictive.
My other CC3D machines are set ACRO+ ACRO+ and 3rd bank to ATTI.
If I loose VTX up high I figure I can flick to ATTI and LOS fly it back if I can see it.
If not then I just crash it.
Once you can fly in a Manual mode, you will never fly in an Auto Level mode again.
