With the recent discussion about rigging regarding how to correct for a roll tendency I spent some time thinking about how often this comes up with phase 1 testing.

There is no empirical data that I am aware of; but, it seems that more often than not the roll tendency is to the left (left wing heavy).

If any normal distribution of builder measurement/rigging variation would occur, it would seem that we could expect half the time left roll off and half time right rolloff, while most would experience no tendency to roll one side or the other.

I'd like to initiate a survey to see if there is a bias towards one side or the other. For the purpose of the survey, it would probably be good to stick with similar design Kitfoxes......including the SS, series 7, 6 and 5.
