This is a small tweak to the Aeroplane Heaven DHC-1 chipmunk flight model.

Quite unrealistically, the vanilla Chipmunk is very hard to slow down on approach, and sideslip produces little drag.

The flight model mod changes this behaviour to more pronounced side-slip drag and and drag in landing configuration. 

 

Make backup of your original flightmodel.cfg in both CIV and MIL folders, and place the mod file in these folders.
