Can push rod bearing be attached to rear side

[chrisO]

Is it acceptable to attach the push rod bearing to the rear side of the servo arm rather than the front of the arm? This would place the bearing closer to the servo motor. I have a slight clearance issue (about 0.125 inch) with the aileron control tube and this alternative arrangement, if acceptable, would fix it. Have looked at dozens of installation photos but can't see one with this type of arrangement so any advice would be appreciated.

Thanks.

It's a shame I invested so much money in avionics from a company that can't be bothered answering simple questions about their products.

Sorry we missed your question the first time. We do our best, but stuff does sometimes get missed especially if it requires deeper research like this question did. We have better tracking of questions in our more formal paths such as phone calls or email support.

The rod bearings Dynon sells won't fit between the arm and the servo body. While on some servos it will barley make it, the clearance is so tight that it poses a hazard of the bolt head hitting the servo body and jamming under some loads, which could jam the flight controls.

Thus, Dynon cannot recommend this. If you source an alternate rod end which gives you acceptable clearance, then this might be acceptable, but you would need to do your own analysis.

Okay, thanks for the reply.
