i was just wondering if some of you experienced r/c ers could give me a list of periodic maintenance points for my volcano. i.e. can bearings be oiled/greased or are they sealed, do the diffs need to be oiled/greased or opened and cleaned, and what types of lubricants to use. anything that prolongs the wear of gears, bearings, ujoints ect. i can be kinda obsessive about preventative maintenance (thats the military for ya) anyway it would be helpful to know the "service points" for my first nitro r/c.
