i used the stock steering servo with Revo wheels and Panther Pythons with no problem

as for oils..i left mine all stock..shocks..diffs..everything..and i broke the buggy track record with my LSP [:@] so i havent even bothered messing with it yet lol

What i did was..put a more powerful steering servo in..and used the old steering on thrtl brake...gives u the breaking power that is much more preferred by most
