I just received my new TxRx. A Carson Reflex Pro-2 LCD.

The problem is, that when i turn the steering just a liiitle bit to turn left. The wheels turn 100% to the left. But if i turn to the right, the wheels follow my movement all the way from 0% to 100%.

I've tried changing the expo settings, but doesn't seem to have an impact. At the moment they are set to 0%.

Then there is something called EPA-ST LFU & BFU which both is set to 120%.

Can anyone help on how to fix this problem?

Did you re-center the arm on your servo to your new radio?
And, if you did, are the wheels straight or close to it when the trim on the TX is at zero?

Does the servo keep grinding away even after you've hit full left? If it does, reduce the epa in that direction until the servo doesn't stop until the wheel and your steering servo are matching what you're doing.

I'm not totally familiar with that brand of radio but I suspect it's similar to other cheaper Chinese un-brand ones due to the need to have both "pro" and "lcd" in it's name. If my guess is correct, failing everything else, it is possible that it's a hardware failure on the tx side as it relates to what it picks up from the wheel motion, sorry.

I did not re-center the arm on my servo, but when they wheel is at neutral, the wheels are straight. The wheels also "swing" out equally to left and right. So the servo is centered correct i think.

Reducing the EPA in the left direction only limits the swing on the left turn, making it not able to turn as sharp, as when im turning right.

I bought the thing on modelsport.co.uk so i think i will contact them to see if they got any suggestions. I guess hardware failure is the only option, if any of the settings on the Tx cant counter the problem?

Thanks for your reply.
