Stemme’s Green Speed Cup, a speed and economy run that was to have sped over six days, ended on the fifth, with all five Stemmes still competing, but with a big break between the top three and the bottom five. Stemme’s web site explains the deletion of the sixth event. “The final race of the 2012 GREEN SPEED CUP was a task of 246 km north of Berlin. Although the weather forecasts looked good this morning, the actual weather didn’t match the expectations. Thus the teams compared their powered flight capabilities as the weather didn’t offer too many possibilities for optimization.” Day five was a cat’s cradle of crossing triangles that added up to 248.2 kilometers (153.88 miles) and was won by Markus Scherdel in his S10VT at a speed of 143.2 kilometers per hour (88.78 mph) while burning 4.4 liters per 100 kilometers (53.46 mpg).

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 Finsterw Heinri and then sped north back to Strausberg to complete the 326.4 kilometer (202.4 mile) course. Uhlig’s winning S10VT toured the triangle at 163.4 kilometers per hour (101.3 mph) while consuming a total of 202.8 kilowatt-hours of energy, achieving …
