Exactly... [8D]

While I'm relatively new to the RC stuff, I've been around all sorts of engines for a very long time. I can't see throwing a new engine on a model, setting the needle valves and go flying.

I want to run it a bit on the ground and make sure everything is kosher giving the engine a little break in time with the heating and cooling between runs to help start the break in process. As long as you don't overheat it, I can't see any harm in doing it. Then watch it carefully for the first few flights for the signs of overheating, and I like to check the temps right after landing the first few times as well to make sure it's running cool enough.

As a matter of fact I'm ground running one right now, and posting here while my new twin is cooling off outside...
