Arrived at the airfield to find it a hive of activity – Andy B + helpers rigging JMX; Colin B and Ken H working on the generator set-up; James H on the Vega trailer. More wind about than we’d ideally like (again!) so no rush to get the toys out. With JMX rigged it was decided to test fly it and check the conditions. First flight established that 40 knots into wind made naff all progress over the ground. Second test flight was need to check the rear instruments so Chris K joined me as talking ballast. Managed to find a modest thermal in which we gained 100′ (vario tested both ways) and drifted us into a nice position for the circuit. On finals coming through the wind gradient saw 15 knots wiped off our speed – fortunately we had 70 knots to start with. Winch then put away and hangar packed.
