Best way to break in a new engine

Ok, I have all new stuff on order, due to come in next week. My first rig was purchased used, this will be my first new setup. I've been able to find very little information about breaking in a new engine. I do know you can use a stand, but I don't know at what rpm and for how long you should run it. I also assume you can put a new engine in a heli, but I'm sure there must be precautions one should take.

So, I'm open to any and all suggestions, links to articles, past experience, etc. on this subject. Thanks!

According to OS, very little break in is needed for their engines. They suggest running the "first few flights" with a slightly rich needle setting (one half turn the normal setting).

I've not broken-in an engine in over 7 years, but with the directions above I've never had to replace any parts on my OS 32 except for the glow plug.

OK thanks fo rthe reply. I guess there will be information about that included with my engine. It is an OS by the way. I looking forward to flying with all new stuff. My heli is an ARF, and I plan on taking my time getting it set up right.

Go slow and understand what you're doing.

I switched radios on my heli and got something backwards and wrecked as a result!

Building from scratch or ARF can result in the same thing. Use your other heli as a reference for your settings too.

And for heavens sake, make sure the throttle servo moves the right direction!

Yea I know what you are saying. While I was getting to know my old radio, I was checking out what happened when I reversed some of the servos. Of course like an ***** I rversed the throttle by mistake thinking it was a different one. Gotta give myself credit though, even though sheer terror was coursing through my viens, by instinct I hit the swith again before the heli got a foot off the ground. Quite a rush!

Gee that sounds easy That Answered a few of my questions, Im looking foward to getting a nitro heli.

sounds easier than the nitro car engines

Much easier than the car engines. Because the helis run with a fairly constant load/rpm they break themselves in.

Oh yeah running in a car engine is like an art there are so many ways to do it.

But then again most of the new car engines have ceramic alloy pistons and rev out at 38,000 So u dont want to ruin ur $450 engine.
