Orange rx goes on the ppm pads on the board. Not sbus.
In config tab on receiver, choose ppm.
Set modes up. Arm switch on Aux1
Angle & horizon on Aux2.
Then in the transmitter menu match Aux1 to the swd switch. 2position switch.
Then Aux2 to swc, the 3 position switch.
Although nothing is setup on the 3rd step of the 3 position. It is acro by default.
If you want to fly just acro all you have to do is set the aux 1 for arming & don't apply anything to aux 2 in modes tab.
All 3 positions will be acro.
Not recommended for newbs without a few hours on a sum.
I would suggest having air mode on as well.
There is that many versions of naze now
I don't know if yours has an osd.
Can you post a pic of your board.
