Ed, can't wait until you put your touches on the interior and panel. The version suggested by MZee1960 seems to work excepting the vsi. I installed my own and used this sound for the R2800

this is pretty "meaty". The sounds from the DC-3 are "timid" and the Howard 500 is adequate, but these from avsim are excellent. These have some bite. Also, the AP tracks the GPS fine, and the GS very well. Nice handling, no CAPS in the config and this is based on Vlads model. Not sure exactly what Brian's mod will do. Could someone elaborate please...? Looking forward to your magic on this project.

Have a great New Year...tp
