Hi,
I am using direct 2-56 metal pushrod between the servo and the engine carburator arm ( YS-110 ).
the engine seat on hyde mount, and during operation the metal pushrod is shaking alot.... i am concern that it will
damage the servo ( and of course i guess it has affect on the engine rpm stability )
is there way to reduce the vibration affect on the throttle linkage ?

Thanks,

I started flying rc in 1975. Now fly rc pattern YS & Webra 160 AAR witch vibrate quite a bit. I use flexable cable from Hobby Lobby.
HLH805 20 Feet Flex Cable Pushrod ..... $ 7.90. No Failures at all.

Hi
The problem is that i have no option to support the tube without bent it ( the direct line between the servo arm to the carb arm is about 2cm near the fuse side and 2cm below the fuse top side ) , that the reason that i used straight metal pushrod
