FS2004 MAAM-SIM R4D/DC-3 Service Patch 1. This self-installing patch corrects several issues found after release of the Douglas R4D/DC-3 CD from the Mid-Atlantic Air Museum, www.maam.org. See included "R4D_9_P1.txt" for complete details and installation notes. Also adds a new radial engine oil drip effect when the aircraft is parked. Does not work with the default FS2004 DC-3.
