RE: $1,000.00 bounty offered to fix COMP ARF A4 steering
Andy,
Model car damper oil, is good quality silicon oil of different viscosity, I would go with a single ram at same size as steering ram single servo and just bleed everything submerged as in the thread above, why silicon oil, because it does not swell o,rings and is a perfect lubrication also does not hold air well and is used for this reason in model car dampers because of it low drag.
Good luck , I have seen Andreas taxi his and all seems ok with his A4.
