If you bought it used it really is a good idea to pull it apart anyway. You never know what might be wrong (not saying that there will be anything). I've pulled my own Revo apart to clean it a couple of times and once I found a crack in my bulkhead, it was on the inside where I would never have seen it until it broke all the way through. You never know, good to inspect. Plus, if you've never taken apart a Revo before it will make you familiar with it, always a good thing.
