What is your EPA settings?

currently -100. I've tried it at -125 then as low as 85 with same results. EPA seems to have impact on the one direction that it turns but none on the other direction.

Couple Q's

Are you pushing the trigger towards BRAKE when setting the EPA?
Are you allowing it to save the settings?

(Important: Always allow the EPA settings to “Auto Save” by letting the voltage reappear on the screen before proceeding with any other adjustments. This takes approximately 2 seconds).

I'm sure you already checked this, but you do know that you have to set the EPA for each direction. Go to the EPA screen, turn the wheel to the right, check/adjust setting, then turn to the left and check/adjust settings.

Edit: Tres slipped in there whil I was typing. He's right..I didn't pay attention it was the throttle servo you were talking about, but it works the same way.

Yes i am pushing the trigger to set both throttle and brake EPA settings. I've also noticed that playing with the throttle's trim button by the steering wheel will move it in the direction of the brake but only very slightly.
I just got the Radio back from HiTec Service last week, they replaced the mainboard in it.

for a test swap Ch 1 & 2 around.

Set the EPA on the T/B servo with the wheel

ok i tried it. The T/B servo responds properly on channel one with the steering wheel, however the steering servo now on channel 2 acts like the T/B did on channel 2.
Like i said before i've tested this with another servo that's working properly and they all respond the same way to channel 2 regardless of what settings i on.

what is your Th EPA set to?
what is your Br EPA set to?

It can only be one of two things then.

Radio settings or radio hardware.

Brake is -115 Throt is +100

HiTech Service sent me a new radio. Apparently this one was completely fixed the first time. The new one is sweeet.

thnx for your help.
