servo or receiver problem

[truggy83]

when I press the throttle trigger the throttle servo does not open all the way. Sometimes it opens a little past halfway, sometimes it opens less. In order to get it to open all the way, I have to turn the trim all the way however when I do this, it opens the carb to much and the car always wants to run on it's own. I replaced the servo with a new one and it is still doing the same thing. What else could cause this? The batteries are new as well in both the transmitter and the car. The transmitter and receiver is a Futaba MS and the servos are both traxxas. The linkage was installed with the servos in the neutral position and nothing is binding the linkage and the carb is not jammed. Any ideas what is wrong? I replaced the throttle servo with another new traxxas of the same kind and it is still doing the same thing.

Do you think that if I were to buy a radio that comes with new receiver and two servors would fix the problem? My hobby shop has a package deal which comes with a 2.4 ghz transmitter, receiver and two servos for a little over $100. I am not sure of the brand but I am thinking about just scrapping all the electronics and starting over. This is getting on my nerves.

turns out it was the potentiometer in the tx. A new tx and receiver fixed the problem.
