Sunday, June 10th showed us good weather once again, and the teams were anxious to find out what the task would be. There were hints that it would be something different than in years past. We were pleased to find that the task was a predetermined course around the valley, with everyone following the same turnpoints. The teams were to fly the 18.25 mile course as fast as possible. The fastest average m.p.h. would win for the day, and multiple attempts were allowed. Most of the teams started around the same time, so the competition was even more of a race than the day before. It was quite common to be in the same thermal as two other teams, and deciding when to bug out and get some distance logged was very fun. This was much like a sailboat race where one team tacks to gain some distance along the course and get ahead of the group. The weather was favorable for sailplanes much of the afternoon. The task allowed for multiple flights, and teams could turn in their scoresheet with the best time to the officials. Several teams, including my own, flew multiple flights. We were even able to start a second attempt without having to land. Team Ellias 647 boasted the best speed on the declared course with a speed of 20.55 m.p.h. After Sunday's event, everyone gathered for the awards ceremony and to see how they had scored for the weekend. Overall scores were good and Team Ellias 647 flying a SB/XC finished the weekend on top, followed close by Team Brady 575 guiding an SB/XC. Team Gradwell 273, piloting an MXC sailplane, took third place overall. Many things were learned this year. Teams really enjoyed the 18.25 mile declared course event of Sunday and the new MXC has great visibility compared to the SB/XC due to a wider average wing chord. Three MXC's were flown during the weekend and the wider chord was declared by many to be better for visibility at altitude. The MXC has a very sleek airframe and promises to bring good things to the Cross Country contests for years to come. There are still a few XC contests left this summer, so don't miss out. If you like sailplanes, watching these birds fly and compete out on the roads is definitely something you won't want to miss. Check out for a list of upcoming events and more info on these fabulous contests. See you on the road! Rich Beardsley's SB/XC with modified wing planform.
