This problem can happen not only with the nose wheel but with the throttle link on four strokes where the carb is close to the fire wall. A simple fix that also allows for a little forgiveness at the ends of the travel is to bend the control rod as per the diagram. When the linkage passes through a fire wall and is close coupled it is common to have it bind somewhere in the arc of the control arm.

Re: what I need to make a good steer in front gear...


The guys have done a great job instructing you with this subject.

Suffice to say that very little nose wheel angle is required.

My old Telemaster is more then 15 years old, probably had two or three nose wheels , vertical bearings and lever arms over the years.

In the setup I try to give a very small steering angle , resulting from the linear rod stroke.

The plane will steer just fine on the ground, reacting to the rudder more then the wheel.

For me the wheel is only the keep a straight heading when taking off, after this its not all that important.

Wide angular movement really is not a valuable property of the nose wheel.

Keep in mind my flying is on a rough , short field , I don't drive around on the ground much.

Yes, nose wheel travel can be less than rudder travel. It's barely needed most of the time as propwash quickly takes over to give the rudder more authority.

Geometry means a lot. If the pushrod is centered in the guide tube at 50% to the right or left, then it only binds at "Straight Ahead" and "Full over"

I also find it easier if you have more pushrod "core" exposed. Wire bends easier over longer length.

Dennis! Thank you for the sketch!

You just triggered a part of my brain that didn't work before, LOL.

If the pushrod came out of the firewall ABOVE or BELOW the control horn, with a loose 90 degree bend on it, poking down through the control horn, then the side to side could be taken in twisting over the entire length of the pushrod....

Not that I've needed this solution yet, but it's always nice to know they exist.
