| Futaba 3PM-X steering issue
Here is my set up Futaba 3PM-X radio Hitec 7950-th servo Using my servo Programmer I can get the servo to move the full throw. Using the radio with end points set at 120% the servo won't move the same distance as the programmer. How can I get the servo to move the full throw with the radio? Thanks, Bernie |

Sorry man but I don't know anything about the programmer. There is nothing special that the radio can be doing different. The only thing the radio can do is set direction (via channel reversing) and end points.

| It really has nothing to do with the programmer other than the programmer tells me I have enough throw in the servo. The problem is when I go full left or full right with the radio the servo does not travel as far. Once again end points are at 120%. Is there a way to program the radio with no end points? I can program the end points with my programmer if needed.

I have the same problem, with any of my transmitters. I think the problem is the programmer puts out the absolute maximum signal whereas the radio only puts out a limited one even on 120%. The simple solution is to set your EPAs a little high on the programer and then adjust till it's perfect with the radio. So far that's worked well with me.

| The radio puts out the industry standard pulse width, that is simply all it can do. It is Hitec who is trying to manipulate that differently than normal. Therefore if you have the EPA's set to the max there is nothing else the radio can do and it is completely the problem of the Hitec.
