Before changing the servo motors, I need to know something about the motion limits and power requirements of the large motors (FT 5335 M from Pololu).

Using an Arduino, any commands lower than 30 degrees do not correspond to movement, thus 30 degrees represents the most clockwise position (viewed from the top).

The 150 degree command is the last one that works in the counter clockwise position, thus I have about 120 degrees available for movement.

At 7.4 volts, two amps minimum is needed to during unloaded motor travel. About .12 amps are required to stay in position with no force applied.
