RE: $1,000.00 bounty offered to fix COMP ARF A4 steering
fix the leak/replace the cylinders.
Submerge everything into a bucket of oil, and make sure EVERY tiny bubble (size of dust specs ) is out of the cylinders, and lines, even let it sit a few hours to make sure air is out.
Then assmeble it while submerged.
Use 2 servos, one for each cylinder if the single servo is not strong enough.
