MK IV question does the pointy end go forward(towards the nose) or the rounded edge?

You need to do a test flight to see which way things go when you release the stick and take your feet off the rudder pedals. Most pilots will instinctively correct for any tendency for the glider to go out of control and into a non-recoverable flat spin or series of lomcovaks without much thought, so it's best to close your eyes for a minute or two to find out what she really wants to do without your help (this works in some relationships with the opposite sex as well).

Once, or if, you recover you can decide how many degrees offset from the centerline the pointy end of the MKIV should be. This is a handy way of correcting most any flight anomaly and can add as much as two points to your L/D.. Oh, when you open your eyes and the ship is in a stable, high speed tail slide, the MKIV should be installed backwards, rounded end towards the nose of the glider. On all properly behaving ships the pointy end goes forward - is that clear?

Thank you for asking.
