If I enable the "Strafe" function and try to "drive" my ROV, the motors respond as in a "jerky" or hesitant manner. They almost appear to be energizing in Forward and Reverse simultaneously in an erratic and random frequency. Kinda of like a "brake" feature. The Strafe function seems to operate more normal than the Left and Right functions when all three are enabled. If I disable or uncomment the Strafe call in the loop, then the Left and Right functions both respond to the RC control sticks as planned. Also, if only the Strafe function is enabled, all four motors respond as intended.
