I have a Dx6i Transmitter/receiver and HFP-20 Programmer. I followed all the steps to program my Hitec 7955TG servo with the programmer to change the resolution to low and to set the end points and failsafe position. However, when I connect the servo to the receiver I do not get the extended endpoints that I programmed but I do get the desired end point when I use the throttle cut off. I checked the servo again with the programmer and everything is as I want in the servo but for some reason I can't get the transmitter/receiver to recognize the new end point set by the programmer. Am I doing something wrong?

Thank you for your help.

Make sure that your EPA settings are maxed out on your transmitter. The psogrammer sets the end points at 900, 2100 with 1500 being the center so your transmitter also has to send that same pulse width in order to see the newly programmed travel in the servo.
