Hello all,
I am curious to see what people?s experience has been with the standard push-pull throttle and mixture cables that Vans sells and see if there are any alternatives out there.
I recently converted an RV-6A from quadrant to the standard push pull. I had some issues doing this. Mainly once I got the correct length of cable, the throws on both didn?t seem to be quite adequate. For the throttle I had to use the very top hole of the throttle arm to be able to get full deflection. For the mixture, I was limited to one hole and it doesn?t quite give me full deflection of the mixture arm and has much less throw than the throttle (which is probably normal but still not enough). It seems that adding a little more throw would cover a lot more applications and not have this issue. Has anyone else experienced this?
Finally, once I got them all in and fired up the motor, the throttle has to be held (or locked) at idle. If the friction is taken off, the throttle will creep quickly to about 30% forward which is frustrating and requires diligent locking. The friction lock on the standard Vans throttle is not linear enough to hold it while still allowing for manual movement. It?s either locked or drifts forward with even the slightest amount of ?unlock?.
Just seeing if this is common, some workarounds, and if there are better cables out there that maybe have smoother friction locking action vice all or nothing.
Thanks all!
