That is not necessarally true when it comes to model airplanes. I once
saw a "speed job" a small controll line model designed to go fast,
that used a single bladed prop, with a conterweight with an engine
speed in excess of 10,000 rpm.


What kind of chugging hunk of a model airplane engine goes 10K? (except at
a high idle?) There are lots of them out there that consistently tach
29Krpm.

I was being conservative as I saw the plane in, probably the mid
1950's, and I really have no recollection of actual RPM as we just
tuned them by ear and flew them :-)
