And here I thought I couldn't build motors because I lacked
metalworking skill -- obviously it's 'cause I don't speak German well

I wanna see the plane this is going into...


It's probably too valuable to ever leave the

Yes, but I've seen some of these engines run at the NAMES show.
There was a guy with a 4-cyl in-line Bentley model that ran
nicely, but another guy had a 4-cyl rotary of his own design
that was a total screamer, turning a 12"+ prop at over 7000 RPM.
I was worried that people were standing to the side of this
thing and if it lost a prop blade there would be a BIG mess to
clean up. Fortunately, no such thing happened.
