Too much flex in my steering arm?
I have a steering arm that flexes about an 1/8 in. in either direction when being moved. I was just wondering if it was okay for it to have that much flex? The nosewheel gets enough travel though; just wondering how it would be in the longrun?
Thanks for your input!

I don't understand what your telling me... are you saying to glue a piece of scrap to the area that flexes or do you mean putting a piece of scrap over the hole, that the wire will go through - although I'm using a screw lock pushrod connector.
Sorry, maybe it's my inexperience, but I'm just not very clear about what your saying to do with the steering arm.

BTW, Thanks for the help!

Are you saying that it flexes when the wheel is not on the ground? (i.e. no friction from the ground). This might not be a good thing. I would go along with the scrap wood support idea.

if the rod is flexing install some type of support at the flexing area,if the steering arm is flexing do nothing,if the landing gear is moving inside the steering arm,then grind a flat spot for the steering arm screw,if the landing gear is flexing do nothing.Did I miss any thing,having trouble understanding the question.

A little flex in the steering can be a very good thing. Do some high speed taxi tests, and if all functions well and the plane tracks for a good take off, I would leave it as is. The more rigid the linkage from the nose wheel is to the servo, the harder it is on the servo every time the nose wheel hits something or slams the ground in a less than perfect landing. A little flex can make life a lot easier on the servo.

The plane hasn't been on the runway yet... I haven't even broken in the engine. It flexes when it's in the stand, but I haven't tried it yet on the ground. I'm positive that it's the steering rod thats flexing and not the pushrod, so I guess it's okay as it is. It does get enough travel, so everything should be fine.
Thanks for all the help!

Oh, guess I missed that fact. I was thinking it was the pushrod that was flexing. If it is the stearing arm I would replace it. The wear on the plastic would eventually cause it to break. Especially if you have a .60 on it and are flying off of grass.
So disregard all of my other posts, I don't know what I'm talking about.
