Default Steering linkage

I've seen slot of people on this site with their servo connected to the right c on their crawlers. I've also seen them connected to the left c. I was wondering if there was any advantages to having it connected to one side or the other or is it just personal preference. I was just wondering if one side would be better than the other for my ax10

I went on the left side, for me it was just preference.

Yeah, that is pretty much it.

Sometimes it depends of the aftermarket steering you are running and where the designer put the servo.

I would have to say that probably 90% of people that move there steering servo when changing there steering set up go to the drivers side with it, it also seems to be the side most after market steering set ups use.

Judging by your thread title and post, sounds like you are asking about the drag link-the rod that connects the servo to the knuckle(the "C" is attached to the axle housing, the knuckle attaches to the "C") When setting up the steering, if the servo is mounted on the driver's side(as most are) the easiest way is to just run a short drag link to the driver side knuckle. But when the servo arm moves, the angle of the draglink in relation to the tierod changes quickly, resulting in some wasted energy of the servo pulling at an angle as the arm swings through it's arc. When the arm is centered, the draglink and tierod are parallel, but at max throw, the drag link raises up, and starts to pull at an angle. With the draglink attached to the passnger side knuckle, the draglink angle stays closer to the plane of the tierod, which is a more efficient use of servo power, but it can be more difficult to run a longer drag link when things like shock springs and upper link mounts get in the way.
In the end it is up to you to decide which way to go, but I prefer the longer draglink setup.

I run mine Gunnar-style, with the servo output shaft closest the LH (driver's side) knuckle.

This was an early mockup on my FF-4 rig, but it shows how the draglink and tierod are staying close to parallel when turning. The bent draglink was tried out to reduce the angle as much as possible, and also for clearance:





When I start building my sportsman rig, I'll probably run this type of BTA setup again.

great pics gunnar. That makes total sense to have the links parallel when at full-lock turn where the stress is the highest instead of parallel at rest the way most kits are set up.
