Hello, I am new to electrics and am having trouble getting a new ESC working correctly. I purchased a new Great Planes SS-60A ESC (GPMM1850) to go along with a Rimfire .46 Outrunner brushless motor being powered by a Turnigy 3300mAh 4 cell battery.

When I power everything on and connect the battery to the ESC I hear the beeps and everything seems normal, but when I advance the throttle the motor doesn't spin until the throttle stick is about half way up. Once the motor kicks on it's spinning at a pretty good speed, not close to an idle. There is no way I could taxi the plane with the current setup as it would be way to fast. What am I doing wrong?

Any help would be greatly appreciated.
