I was using the FR C-54/DC4 in P3D V3 and at that time, I found a really nice engine set that sounds close. I migrated it all to P3D V4.5 and it all still works okay. I missed the sale for the
P3D 4/5 version by a few hours. Will keep a watch out for another 50% sale.

I don't remember where I got the engine sounds and interested in recommendations for other PW R-2000 sounds. I think the DHC-4 caribou would also come close and it uses essentially
same engine.

I have attached one of the startup wave sounds as a sample.
