I worked on a buddy's gun who had a modify AR latch installed (the one for the gearset) and it doesn't work on regular gears - ie. would not catch the latches on the bevel gear. After maybe a couple hundred rounds through the gun, his brand new modify piston (garbage IMO anyways) had the first tooth (from the back) folded/broken to the front of the piston and significant wear on most of the other teath on the 'wrong' side - caused by the piston moving forward while the sector was still engaged. So the AR latch is very important little piece.

On the motors topic, yes they will spin the other direction if the leads are reversed (outside of the grip/mechbox). I found on the motor I did it to that it was VERY slow compared to the proper direction. I don't believe this is bad for the motor, just inefficient. If you look at systemas new new Revolution mechboxes they have 4 gears in the mechbox - the extra gear causes the sector gear to reverse direction on a 'normal motor'. This is why Systema made a custom motor which is built to run in the opposite direction, so motor choices for the Revolution will be slim it seems.
