Study the above threads: STICKY: Install procedures w/sources, UOP links Red BAron 3D Newbie Info for LOTS of helpful info...the best I've seen in onme place in all my years of RB3d. I also played RB1 (with Bob Church's XBaron patch) and loved it. RB3d is much better once patched. My particular favorite is Hell's Angels superpatch. Easy to add and you get plenty of upgrade. Remember to set flight model to authentic when using patches that modify the flight model like HA...and set the plane models to custom.
