I think this is a 3-channel, disguised as something else. I'm not seeing servos anywhere, and there may be only one inside the thing.
Looking for more pics...
The Tx for this model, the Double Horse 9100, is equipped with "trimming" sliders on each axis that moves.
I didn't determine if they were the same as, or finer adjusting than, the knobs you see at the upper corners of the unit, that do function.
