If you are asking if a cylinder sleeve and piston wears out because of normal use will they replace it? Why should they? Get a grip do you know of anything that is guaranteed against normal use or if the owner does not take care of it?????????? Come on grow up if this was so every company in the world would go broke not just RC companies. Do you know of a full size car that is guaranteed for life??????????[8D]

didn't volvo give you a free, new car if you were the original owner of a 250,000 mile volvo back in the day?
but really, any company that gives you a warantee on normal wear and tear would go broke quicker than me spending a day in vegas.
