Grampi-

Dynamite sells some 3/16x5/16 (sealed) flanged bearings, 4 for $13 at my local hobby shop. You could probably find them even cheaper at a local bearing shop. Duratrax also makes some that are cheaper than Team AE oem bearings.

I have a CV-R .12 engine, I fabbed a metal carb arm. If you can do that, I found the action to be smoother as it did not bind from the plastic arm tweeking slightly during operation. I also have a 'safety' spring on it to return it to idle if I lose control of the car. I learned that lil tip after the horn came off the servo and my car went WOT into a wall.
