With lucrative broadcast deals and cup competitions now crowding calendars, the sport of drone racing has become one of the primary factors driving the surge in demand for consumer drones. Mountain Dew and DR1 Racing earlier this month announced a special DR1 Invitational presented by Mountain Dew. The one-hour broadcast will air on Discovery Communication's Discovery and Science channels this August. That's just one example of the forces driving a consumer drone market that's expected to be worth $4.19 billion by 2024.
