One thing - when you do get it and start breaking it in on the ground, mount it on a dedicated test stand. Not your model.
I just got mine yesterday and I would really like to do the ground running before I'm able to mount it on the airplane which will be awhile. I'd really like to fire it up before I can mount it just in case there are any issues, which I don't anticipate. Plus I really want to hear it run!
I know that DL says not to use a test stand but I have to believe that unless you mount your engine up to a big ol' block of steel it should be able to move around enough to not break the mounts off. I've seen plenty of videos of this being done. If run on test stand, what's the best way to do it?
