Gerolf on Sprogs

During the British Nationals Competition in Laragne at the beginning of August Gerolf gave a very interesting and unbiased talk on sprog heights and the ramifications of too low and too high settings. The talk hit home with a lot of pilots and over the next few days I spent a fair bit of time measuring gliders – with some ‘interesting’ results.

Gerolf gave Markus Kinch permission to film him (so I’m told) and here are the films which Markus has split into 6 parts due to limit on youtube movie size. The sound is not brilliant but if you were not there and have never had the importance of sprog measurements explained to you I urge you to watch, learn and take action…….
