This year we have made 3 experiments with long-range internet control.
In all cases we set our virt2real board instead original RC electronics. All servos and motors was connected directly to PWM outputs with no any additional shields.
Fires experiment is RC car. The driver was in Moscow and the car is in St. Petersburg (~600 km)
Second experiment was the most difficult. We fly on Bixler 2 plane over internet. Plane was in S. Petersburg, pilot in Moscow (~600 km).
While third experiment we set our team's record: driving over 7150 km. Car was in Shenzhen, driver was in Moscow.
