yes i saw it flying !!
the guy made a low pass maybe 1,5 meter above ground at 350 Km/h !!!!!!!!!!!!! he said he downgraded the specs on the turbine to fly at my city since its illegal to pass 400 Km/h on RC.
he said top speed is around 500 Km/h when he flew over a farm in the interior of the country. (no regulation
)
