Cool looking animation    (http://bbs.hitechcreations.com/smf/Smileys/default/smile.gif)

In older radial-engines one of the connection rods were solid master-rod (just like in cars) where other rods were connected in its bearing-frame.

Fascinating stuff!  I've never seen what the inside of one a radial engine in motion looks like.  For the Pratt & Whitney Double Wasp R-2800, they used 2 rows of 9 cylinders instead of the single row of 5 in the page linked above.

Why didn't they do a triple or quadruple row radial for even more power?  Why are there odd numbers of cylinders used?

The P&W R-4360 "Wasp Major" had 28 cylinders in 4 rows.

Some nice links (Yeah I love engines   (http://bbs.hitechcreations.com/smf/Smileys/default/biggrin.gif)):

Bristol Centaurus (http://www.marss.com/bristol.htm)

Here you'll find some info about Napier Sabre (http://user.tninet.se/~ytm843e/)

And little about sleeve-valve engines and history (http://www-g.eng.cam.ac.uk/125/achievements/ricardo)

Heres nice picture (http://www-g.eng.cam.ac.uk/125/achievements/ricardo/page41.htm) showing how sleeve-valves worked in Tempest/Typhoon's Napier Sabre or Bristol engines (some RR's got them too?).
