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

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

You can build nice engines if you speak English, this guy speaks the
Queens English mind you. http://www.enginehistory.org/merlin_xx.htm and
http://www.modelenginenews.org/galle...gle/index.html . Shame it
didn't go in this
http://blogs.aviation.ca/index.php/s...el_masterpiece
as they are the same scale. I read somewhere that Barrington Hares may
have built his own milling machine which he then used to build the RR
Merlin.

This one is also quite impressive and the engine is fitted to the car.

It's probably too valuable to ever leave the
earth.

A friend of mine has completed a Bentley and is now building a scale
Merlin.
He is an EXCELLENT pilot (aerobatic champ and all that) as well as an
excellent machinist and a perfectionist

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.

Hi Jon

I was under the impression that Rotary (radial) engines needed to be an
odd number of cylinders. Have I remembered this wrong??

Well, most radials of the Pratt & Whitney variety were based on
7 or 9 cyls. per bank, but there really is no reason it has to
be that way. It may balance more easily or run a little
smoother that way, but there's no reason it has to be like that.

This guy's rotary was nothing like the traditional rotary
engines, though, I think the pistons were linked to the "crank"
by a cam and a roller bearing. The pistons clattered against
the cam when turning it over by hand, they apparently needed
centrifugal force to hold them out against the cam.

Yes, he's quite nuts. It is not a model, the one he is currently building is
1:1. And he also attempts to get the permit of the "Luftfahrtbundesamt"
(the flight agency) for use in planes (we do have *very* strict laws).
