Yeah, they come with manuals... but that wasn't the question...
The purpose of this thread was to find out, in general, what people do when they go through their break-in procedure. You can do pretty much the same stuff with the engine in the model, strapped down, as you can with it in a break-in stand... I was curious to find out how many people chose each of these methods. In addition to this, many people don't follow the manual procedures and do their own thing... like just fly it rich for several tanks, or not worry about break-in at all (yikes)! For example, my OS50 SX-H engine manual says to just fly it rich for break-in... while other's highly recommended getting a prop and breaking it in on the bench because they had much better luck that way.
It was a general question with general answers expected... and much more specific answers welcome as well.
