Best way to align steering?

[Ares]

hi guys, my car seems to veer off leftwards. servo-saver was mounted on servo at centre. no adjustment on tx yet. prefer to do mechanical linkage adjustment. anyone got great ideas as how to set it up properly? thank you.

You are only able to get it so close when you mount the saver. No way you are going to get it mounted spot on. The fine tuning is done with the trim settings on the transmitter.

thanx robmob,
do i set the sub-trim or trim? and do u mind explaining what dual rate is? i read but still cannot unnderstand.

use trim to fine tune, sub trim is more like u adjusted the center point on the servo (like taking the arm off and moving it one spline over)

Dual rate is - lets u slow down the servo in the middle or movement - to help driving all over the place

so, sub trim actually moves the original centre point of the servo from neutral...is that it? by using sub-trim, it won't shorten the throw of the servo travel right? thanx , man. appreciate it....now for me to try and understand dual rate.

Yup, sub trim is like a fine tuning trim. Really helps you center the trim. I don't have that since I have all cheap radios on my stuff. But it's a pretty cool feature.

Dual rate. The name really doesn't describe what is going on. My take on it is like ATV. Increasing dual rate reduces the total servo throw. It's typically used for steering. A simple demonstration. Turn your radio on. Turn your car on. Turn the steering wheel on the tx. Look at how much the wheels turn. Then turn the dual rate adjustment all the way in the opposite direction. Then turn the steering wheel. You'll notice that the wheels turn a lot less. This allows you to limit total steering response for track conditions. If you reduce steering throw you are less likely to spin out or make horribly extreme overcorrections in your steering. Plus, if you don't need the full range of steering for a particular track, dialing down the dual rate will help you make smoother turns. And smooth is fast...

thanx everyone for the kind response...now i know a bit more each day...its hard to keep up with the technology when you are old
anyway, there's still tons of function in the 3PK that i haven't explore yet.rest assure that i'll try to figure it out first...but then again, if all else fail, i know just the place to ask for directions....

to make it easy, just set the menu level to 2, level 3 is a little overkill for most lol..
