it is the nirto component in the fuel and oxygen that will do most of the corrosion problems so coat the bearings with after run oil to displace the nitro laden fuel residue.
Disagree. I don't think nitro is corrosive. The methanol we use will absorb water out of the air. The water is what causes the corrosion. You want to get the methanol out of the engine and coat it with a protective film of castor oil.
