The Victor nominally turns a measured 1.5-2.0 ms into a 0-100 forward value, but the output actually stays at zero for at least the theoretical 0-6 range, and it reaches 100 with an incoming pulse width that is somewhat less than 2.0 ms. It turns 1.0-1.5 milliseconds into a 100-0 reverse value, with the same holding at zero until it reaches 7 or so, and getting to 100 before the pulse width gets down to 1.0 ms. Experiments have shown that the Victor's center value is not precisely 127; it's actually more like 134. So the Victor output isn't symmetrical around the theoretical neutral value of the IFI system.

Those ranges are for the factory setting, correct?
