Two things to think about.
1). In the past, using the Victor 883 controllers, there was a built-in deadband of 10%. The controllers wouldn't start driving the motors until more than 1.2 V was requested. I believe the 884s don't have that deadband. Have your software folks put one in the code. EXAMPLE - If output is less than 137, then set it to 127. Something like that.
2). The drill motors run differently in reverse than forward. More than likely, you have one motor running backwards relative to the other. This is expected. Think about it. There will be a slight efficiency difference between your port and starboard motors since they are facing in opposite directions. This has something to do with the brushes being asymmetric.
The 10% deadband should clear up your problem. Good Luck.
