Marv,  I spoke with Bill Harrelson yesterday about our new winglets we have developing for the past 3 years for the Lancair 4's and ES's.  The last of the flight tests are completed and we are ready to move forward with tooling and construction of the winglets.  There are several tests which we have data from but the main safety improvements are , low speed handling, lower stall speed, lower landing speed, increase in cruise speed and or fuel savings.  I would like to write a flight test report for LOBO and have it published in the next newsletter. Here is a photo of the Lancair 4 P Turbo ready for touchdown at 75 kts.  Regards,  John Neel  Cell 435-632-2917
