Toe in setup

[nivlacf1]

was searching and was surprised to see there is no dedicated page to help on setup, if there is can i be pointed in the right direction please as i could not find it, my issue that i am having is, i am setting up a T3 xray and when i set my toe to 1 degree out on Turing the steering with the transmitter it never returns back to 1 degree out i set just randomly returns to 0 degree or 2 degree or somewhere in between sometimes back to 1 degree deepening on weather i turn it left or right, now i understand its and old car and there is a little play throughout the whole steering mech, so is this normal and under power will it return to the 1 degree out i have set and it is just on the setup board it does not look good? any help or advice would be much appreciated thanks
