df 29 stering issue

[driftah]

ok I have a df29 that I am having an issue with...the issue is that I have a wedge under my steering servo near the stern to put it at the proper level as the rudder link but im not happy the rod that goes through the stern attaching to the rudder slides in an off center manner.ie not linear its more like an ellipse shape.Any ideas on how to get a straight up linkage so I dont stress the servo or the mount to the hull? I am using a captured ball as the link on the rudder end to give it more of a chance to swing straight fyi..any help?

Hi,

Could you post a few pictures of your setup of the steering servo and rudder so I can have a good view of how the pieces are lined up?

Thanks

If I understand what you're saying, it's impossible to get a perfect linear motion. Both the rudder arm and the servo horn swing through an arc. Even if you had a linear servo the tiller arm still follows an arc.

You can also adjust the angles by using a Z bend with the steering pushrod.

You just need it to be steady where going through the boot. We'll need pics to help further.

If this is the problem, and the rod drags on the hull where it enters/exits, one way to minimize this is to use a larger diameter through-hull tube. I'm just guessing this is what you're talking about

Yup. I usually set my pushrod off center to compensate.

Yep off center and the bigger rubber boots, think they are Du-Bro. 3 piece units that come with a plastic sleeve to go through the hull.
