I believe the issue is that JR, Futaba and HiTec designates the pulse for center and endpoints differently. If you had a HiTec radio, it should be dead nuts on...

That's my only issue with the programmer... it would be nice to calibrate it to a specific radio... so that the programmed pulses matched that of the radio.

Maybe that would be a great feature... or better yet, a USB computer interface that would allow connection to a PC, with auto calibration of the radio.

The way around it is to calculate the pulse offset and add/subtract it to the Hitec numbers. So if you are hitting zero on the programmer, but the JR radio is putting out 50 or whatever... you might need to program the servo with -50... THen when the JR tells it to center... it's back where you want it.
