propeller rudder interfernce

[proprud]

I'm working on a propeller rudder interference problem with BEM. Do you know where to found some experimental datas about that to validate my results? I have a Molland article but it's not so helpfull as I need...
Thanks a lot for your help.

Could you give us a clear description of the aircraft configuration that's having problems? Is this prop wash inducing vibration in the rudder?
