Hello Guys, I've got a Zenoah G23 on my Ultra Stick 1.20. This requires a bellcrank linkage to link the pushrod to the throttle arm.

Anyway, I'm trying to set up my 9Cs "idle down" and "throttle cut". As you know, it is just a few millimeters of movement in the servo arm from "end point" to idle down to throttle cut.

All this seems to be lost in the minor slop in the linkage, since it has to go through the bellcrank.

I'm just going to replace the old pushrod, bellcrank, etc, and see if I can get the slop out.

Has anyone struggled with this?

ps don't tell me about the Zenoah Easy-Link (it is anything but)

THANKS!!

Is there any way of using a Cable type pushrod that can be bent to the right angle?

I'll check with my LHS, but it seems like it would be a stretch, distance wise. Thanks though.

Use ball joints, no slop.

I do have ball joints at the end of a coupler that connects the bellcrank to the throttle arm. Still with the slop

How about a light spring - like out of a ballpoint pen - to keep a bit of tension on the throttle at the low end. Set it so that it is not compressed when the throttle is open. Maybe by silver-soldering a washer to the rod and butting the spring on the inside of a bulkhead.

I have not tried this - it's just a thought.
