The F3B closed course speed record is flown on the standard 150 meter speed course. It is the speed task as flown at the Worlds. To break the F3B record, which I believe is around 14.00 set by DP at the 1999 worlds, would require exceptional skill as well as amazing thermal conditions. Slope flying wouldn't do it due to the extra distance flown due to the vertical and horizontal components of the wind. The optimum conditions are where you have a very big thermal in the middle of the course, creating downwind turns at each end. Plus nerves of steel so you can nail each turn. I think that he is referring to the FAI ultimate closed course speed record. That requires a 200 meter course with electronic timing and two passes, one in each direction. This is similar to what was flown at washington last year. Hope that helps. Aaron RCSE-List facilities provided by Model Airplane News.
