During the past summer vacation, a 15-year-old boy made a model plane on his own in less than a month. Then he flew it successfully, which surprised all the people around him.
The boy named Li Banghua is from Hefei, Anhui Province. He made the plane completely by himself. The plane is 0.6 meters wide, has a wingspan (翼展) of 4.4 meters and weighs about 40 kilograms. According to a local report, Li just finished his high-school entrance exam a year ago and got good grades. After the exam, he threw himself into the work of making the model plane right away.
Li has been interested in model planes since he was a child. Besides, he has been studying an building model planes for years. This time the model plane is the largest he has ever built and he considers it the most successful one.
Throughout the process of building the plane, he came across many failures. “But the biggest difficulty I had was that the adults couldn’t understand me well,” Li said. “When I said I was going to build a model plane, a lot of adults thought it was impossible. But I decided to keep on working hard. That is because once I start something, giving up is not a choice for me.”
What’s more, on May 1st, 2022, he took the “fire fighting drone” (消防无人机) to a test flight in the field of his hometown in Feixi County successfully.
When talking about his future, he said he dreamed of becoming a plane engineer.
