The first reports from others experimenting with lower surface Deturbulator Tapes ( http://www.deturbulator.org/Progress-03192011-15Cheap.asp ) are now coming in. You can read their comments at http://www.deturbulator.org/participants.asp .
If you are experimenting with Deturbulator Tapes too, please report your comments to me (http://www.deturbulator.org/Contact.asp ) and indicate if you do not want them posted to the website.
Anecdotal observations are welcome, but performance measurements are needed. It is not difficult to make comparative before/after measurements using your IGC logger. A manual and spreadsheet are available at http://www.deturbulator.org/files.asp .
