"We started making profits only at the end of last year. Before that, we had to invest heavily in technology research and development for the electronic remote controllers, which was a brand new business for us," said Xie.

Citing the success of DJI Technology Co, a major domestic drone maker, Xie said startups in Shenzhen usually go through problems before they turn a profit.

"We realized there would be difficulties, even as we began to transform our business. We did not want to simply be a supplier for toy producers. We wanted to develop our own brand," said Xie.

DJI Technology became a household name in the drone industry over the past two years, after its expansion in the international market.

According to Xie, his company has a long-term strategy to enter the global market by introducing more advanced facilities and equipment in the model airplane electronics industry. For example, the company is developing chargers for radio-controlled vehicles and remote controllers.

"Our ultimate goal is to catch up with foreign players in the industry," Xie said.

According to Xie, fewer than five similar domestic companies make electronic remote controllers. Internationally, the market is dominated by leading brands such as Japan's Futaba Corp.

"We will look for investment (overseas) to expand our international presence," Xie said.
