[azroyhelmy]

Does any one have the 3 sisters engine plan other than this one http://npmccabe.tripod.com/3sisters.htm ?

HMM not sure what you are looking for.
A better organised drawn set of plans for that engine a better 3 cylinder oscillator design?
Elmer Versburg did a 3 cylinder radial

YES! that is what i'm looking for..but are there more than 3 cylinder one? maybe 6?

I think what you are realy looking for is multi cylinder air powered radial engine. There are many variations on this theme. Chuck fellows here just did another fantastic 3 cylinder radial build. Brian rupnow did a 5 cylinder radial oscillator . That was published in Home shop machinist mag IIRC the plans are in the download section here. Rudy Kouhoupt has published 5 cylinder radial plans .

Liney machine also had a couple radial and the list goes on.

I think if you search radial(steam or air) engine either here or on Google you will find a bunch of info.
