I have most of the P-166s installed. I have found two things that I do not like...but they may well just be my personal preferences at work.
1) The view from the VC is bit low...so I raised the viewpoint to suit my own taste....well, just on the A model at this point. I changed the eye point setting from X, X, 2.15 to X, X, 2.5. This gives me the kind of view over the VC panel I like.
2) The DL3 or what ever it is, the one that is aliased to the Kingair 350. I HATE, DESPISE, DETEST, CAN NOT TOLERATE the sound of the Kingair 350. Don't even use that sound on the Kingair 350. I have a single turbo prop pack from Alpha Sim, not sure which freeware plane it came with (possibly the Turbo Mentor). It is for CFS2, FS2002 and FS2004. I tweaked the sound config to make a nice twin engine turbo prop package. I will have to dig around and see which package the sounds came with, get permission from Phil or one of the other Alpha Sim members to upload the package to the library. Sounds much much nicer than that shop vac sounding stock Kingair 350 package.
Oh, another tip: Use DXTbmp to open and resave the texture files of each package without Mip Mapping. Really clears up the fuzzies on the externals of these planes.
