Default Servo mixing question!

Hello as you might know i now have an MCD Monster truck, well in my Fg i got away with one steering servo but in this you need 2 which is fine as i have 2 hitec 5745mg servos.
But i don`t understand mixing i have them on the Y-lead and thats working fine both seem to be moving exactly the right distance left and right.
I tried mixing as i never have before on my Spektrum DX3R, i set primary and slave to steering and read the manual and tried negative and posite values and all this seems to do is adjust the travel! Is this all mixing is supposed to do? Because surely i can just do this with the travel adjustment option.
Any help in laymans terms would help as i have never used mixing before.
thanks in advance

You don't need steering mixing - simply plug the steering servos into the y-lead and just make sure the steering turnbuckles are equal length....it's worth upgrading the turnbuckles to the L/R threaded ones (149-3-DS-1) - as supplied with the truck to operate the brake.

I use the mixing when using an extra servo for the front brakes. This way this servo only works when I use the brakes. For steering I would use a y connector instead.

Totally true, y connector for steering servos, I use 3rd channel mixing for my front hydros so i can adjust the front to rear brake bias.

Y harness is the simpler way to go and should work just fine. Mixing the third channel with the steering to aviod using a Y harness would only be useful to eliminate a single connector and wire trying to power two high torque servos. If this is really a concern you can always power the servos directly from the reciever battery and just run the signal wire to the reciever. Make sure to set a failsafe and be prepared to charge that pack often two 5745 servos suck down alot of juice! Good Luck.
