Dom flying his modified Jetiger. Its first flight clocked a GPS measured ground speed of 258 km/hr (around 160 miles/hr). I had difficulty in capturing smooth video on the first flight and got a bit better for this the second flight that logged 125 kts (231.5 km/hr) although these speeds haven't been confirmed by radar. The original Jetiger is discontinued, but the website claimed that it could reach speeds of up to 100 mph on 3S.
