Jason Chandler's aircraft at AIR.C74.Net work fine under 64-bit as none of them depend on plugins. Grumman G21-A Goose Package and the Bombardier Challenger 300 Captain Edition by Ddenn Designs using the standard SASL 64-bit plugin. STMAs Husky, Beaver, Otter and Super Cub are now 64-bit. The Pilatus is still not fully 64-bit compatible. Regards
