I don't think you need to. You could if you felt more comfortable though. I don't know where you heard about CAing bearings, but I don't think that is necessary. My landing gear is the 'normal way' and I havn't had a problem. As for loctiting, you only use loctite on metal to metal. The frame screws go into plastic, so they don't need it. :rainfro: :drowning: :sunsmiley :boxing:
