Post Straight drift
I wrote a short Arcadecontrol program in RobotC for my Vex IQ clawbot. Even without the gyro installed, the robot drifts forward (slowly) even when the joystick is in 0 position. I tried re-calibrating, but no luck. My program is simple, I just set the Arcade mode and then Armcontrol for adjusting the speed of the claw and arm.

Try increasing the threshold (or "deadband") value, the third parameter in the arcadeControl command. This parameter tells to robot to essentially ignore any joystick commands within the +- 10 value range, and can help reduce drift if the robot is moving forward even when the joystick is centered.
