Sometime the 727 does seem to have trouble tracking the VOR radial, yet at other times it will behave perfectly fine (until it gets very close to the VOR).
I can't say if it's the wind affecting it or not (I never turn the wind off, and also use AS2012 real world weather a lot).
IMO, I find it strange that people would buy a product like the CS 727 and ONLY fly it in Clear Weather! :o
