@ OzMo: you are right, clevises not treades, just smooth inside.

@davidgeorge212: The treaded clevises were on my 1st. plane (Hobbistar 60 MK III), anyway original clevises were swaped for treaded Sullivan black plastic clevises with lock. These not treaded clevises that we are talking about are for a Super Sportster 120. I really don't see the point of the soldering, beingthatthe clevis cannot turn on the rod,as is hooked in the servo arm. Of course , I can be wrong.

@skylane_182: The pushrod are outside the fuselage, plane is a super sportster. Again , your post agrees with my idea of not soldering pushrod/clevis.

Thanks to all three responses.
