I just checked the specs for the OS controller at Tower Hobbies and the specs listed say it a lower peak amp than the OS instructions list.

Peak Load Current: 70A (85A 5 seconds)

Overheat protection

Probably specs for a different controller.

It also says it has 'reverse' capability, not sure why we would need that for airplanes, but it would be spectacular on final approach.. ;-) Probably a carry over from another controllers specs.
