Robert Adam, one of the organizers of the Green Speed Cup in Germany and pilot of the Flight Design CTLS that ended the competition in seventh place, shared some information on the challenges faced by pilots in this year’s event. “We had 12-15 knots crosswind today (only a little less yesterday) and Tim-Peter (-Voss) managed this demanding taildragger (the SPACEK s.r.o. SD-1 microlight) calmly!”  This very light and short-coupled airplane flies with a variety of two- and four-stroke engines, but Voss’ had a Verner JVC-360 four-stroke unit of 38 horsepower.  It averaged a little over four liters per hour fuel consumption per 100 kilometers (59 mpg) over the practice day and two contest days.  In the Green Flight Challenge, it would …

The second day’s competition was a complete turnaround of day one’s results, with Wolfgang Uhlig taking the crown and Markus sliding to fourth place. Most interesting, the Diamond DA40 TDI, a four-seat Diesel-powered aircraft flown by Daniel Hirth, took second place. A longer event than day one, the task required pilots to fly from Strausberg down the longest leg of a scalene triangle to Klix, a village in Saxony. From there, they turned northwest to …
