The pilot reported that the takeoff was being conducted in a crosswind which he estimated was from the left at 10-15 knots. The surface of the 10 metre wide strip was covered in loose gravel. At the beginning of the takeoff roll, the aircraft began to weathercock to the left. The pilot continued, believing that directional control would improve as aircraft speed increased. However, this did not occur and the aircraft ground-looped, striking an embankment at the edge of the strip. The pilot reported that the aircraft was equipped with a small tailwheel which had limited effectiveness on the soft loose surface. Also, the aircraft was a late model Thruster aircraft which had a greater keel surface than earlier models because of its enclosed fuselage. This was the first time the pilot had operated the aircraft in crosswind conditions. The operating manual for the aircraft indicates a demonstrated crosswind capability of 15 knots. This accident was not the subject of a formal on scene investigation.
