yesterday just upgraded firmware for RC MA2 to support MA2s.
next hope that it will be new fw for MA2 with O3.

There should be additional hardware necessary...

Doubtful MA2 will get the O3 update--  from A2S reviews there are 4 antennas (2 front legs, 2 back legs) and MA2 only has 2 in the front.

MA2 doesn't have the 4 antennas like the Air2S for OC3.
