I have just bought an MVVS 26 IFS for my BTE Flyin' King. Much more power than it needs, but I got a very good deal and couldn't resist.

With this engine, the plane flies nicely at just 1/4 to 1/3 throttle (with 50% negative expo). I usually spend most of the time flying around at low rpm. The question is; will this hurt the engine in the long run?
