Mike,

I've noticed this myself. I appears the ratio between the programmer and the transmitter is not 100%. It is also alluded to by the gentleman who put together the programming videos. I've gotten into the habit of initializing the setting of the endpoints with the programmer and then check them with the transmitter. Using the value from the transmitter setting, I then adjust the programmer plus or minus until I arrive at the point where they are 100% with the transmitter.

BTW, now that I think of it, my primary transmitter is the Futaba 9C. I will check this out with my Eclipse 7. I do know the Futaba's centering is ~1518 and the Eclipse's is ~1500, the endpoints are also probably different.
