MTH PS-2and PS-3

yes.

Thanks I've done PS lash ups but never tried that 

There was an instance in a DCS version, that if the PS3 and PS2 engines were in certain configurations, the direction got messed up. MTH posted that this could be cured by simply pressing the direction button a few times before running. 

 Tell that to my engines that tore each other apart! 

Joe,

I reported that to MTH R&D and it was corrected in DCS 6.0.
