BEIJING, China (AFP) — Drone owners in Beijing flocked to designated buy-back sites this week, looking to sell their devices for as much as possible ahead of an impending citywide ban.

New rules in the Chinese capital ban not just the flying of unmanned aerial vehicles but the possession or storage of them, meaning owners have until 15 November to get rid of their drones.

At several authorized buyer sites across the city, Agence France-Presse (AFP) witnessed queues of people waiting for staff to appraise their drones and negotiate prices.

All sites had a visible police presence, indicating the sensitivity of the new laws, and most people there did not want to talk to AFP.

At the flagship store for the world’s largest drone maker DJI in Beijing’s business district, around a dozen people queued on Thursday morning hoping to sell their drones back for a reasonable price.

Users can sell devices at approved buy-back points and receive a government subsidy of 30 percent of the resale value — up to a maximum of 3,000 yuan (nearly $450) — before 31 October, and of 15 percent until 14 November.

Alternatively, they can recycle them for a subsidy of 200 yuan, or ship them out of Beijing free of charge.

“I think (the ban) is reasonable. I can understand why the government wants to ensure safety and manage the airspace,” a 48-year-old drone owner surnamed Wu told AFP as he sat in a queue in a DJI store waiting to sell his device.

“After all, Beijing is the capital,” said Wu, who bought his drone six years ago for around 6,000 yuan.

He was hoping to get at least 1,000 yuan for the sale, which was what he had been given as a preliminary estimate on the official re-selling app.
