That moment is shining.
When the red Ghost four axis aircraft soared up on the lawn of Renmin University, the eyes of five Lei Feng.com friends, three men and two women, and countless beautiful or beautiful, or beautiful, girls wearing graduation dresses and posing for photos were immediately attracted by it and looked up.
God was very helpful, and sent us a rare clear sky, which drove away the killer of various aircraft - Feng.
How we hoped that the red and booming Ghost four axis aircraft could turn several somersaults or suddenly drop a big banner, but it didn't. Ghost just stayed quietly in the air about three floors high, almost motionless, even if it walked a few steps in the air, there was no suspense.
"Why does everyone have a dream of flying?" asked the companion. I thought for a while and didn't answer. I didn't want to drop my book bag or appear ignorant. Maybe I felt too natural.
If I ever played with a remote-controlled aircraft (helicopter) when I was a child or not, I can definitely say that Ghost four axis aircraft is much simpler than toy helicopters. At first, my friends wanted me to operate Ghost, because I had a little foundation of mini helicopter model, but I finally found that those technologies were completely useless, and that "people can play Ghost".
The little trouble behind simplicity
Although Ghost is as simple as a "fool drone", the work before takeoff is not pleasant. If it were not for the "flying dream" and "struggling spirit", the five partners would probably be disgraced in front of hundreds of white legs.
Ghost four axis aircraft probably includes three parts: body, mobile phone app and communication box. Before going out, fully charge the batteries of the body and the communication box. The batteries of the body need to be taken out for charging. The communication box can be charged directly using the MicroUSB interface just like the mobile phone. The mobile phone app and communication box are connected through Bluetooth, and the communication box is connected to the body through the 433MHz wireless band. The communication box needs to be near the mobile phone (no more than 10 meters) to maintain an effective Bluetooth connection, while the antenna is facing up to ensure the radio signal.
Our "unhappiness" lies in the part of Bluetooth connection. According to the official user manual, you should first open App GHOST, and then connect Bluetooth. But our actual experience is that you must pair in the Bluetooth settings of the Android phone system settings, enter the pairing code 5250, and then find the Bluetooth device in the "Settings" of the GHOST application again before you can connect and use it normally. The Ghost team of Yihang has sent a statement that they are trying to solve the complicated problem of Bluetooth pairing, "as long as it is a software problem, give us some time, we can solve it".
That's it. After learning this skill, there will be no problem.
Unique design: the remote control app only works when you fly more than 10 meters
The reason why Ghost four axis aircraft is simple is that it adopts a quite unique design, which completely automates the "takeoff" and "landing" processes that are the most difficult for aircraft equipment ——After pressing the take off button on the mobile phone app, Ghost will automatically fly vertically to about 10 meters in the air, hover and wait for the mobile phone command, rise (no descent) or fly horizontally around. In the process of landing, you can first press the "Return" button to hover 10 meters above the takeoff point, and then press the "Landing" button to slowly descend.
Lei Feng.com believes that through this design, Ghost has realized the slogan of "making flying no longer the patent of a few people". However, those students who want to show their technical strength, especially the grumpy men, should lose the chance to shine. [Update] But don't worry. Even the ordinary version of Ghost has reserved remote control and other interfaces for professional users. If you want to play tricks, you still have the opportunity.
Report of 5 major test results
Endurance. We didn't make a specific test. It seems that it takes about 10 minutes when the battery is not fully charged.
Maximum height. 50 meters is OK (see the picture in this article). No matter how high you are, you will not dare to test for fear of falling down and hitting people. Xiong Yifang, founder of Yihang Ghost, told Lei Feng.com that their test result was "at least 760 meters". So for the next test flight, we decided to be bold, at least 100 meters away.
Maximum load. It's OK to lift a Xiaomi 3 mobile phone, about 150g (see the video for details). This is the only equipment we have on hand that can be tied up for testing. The test data of Yihang team is 1000g, which we will test next time.
Stability. Excellent. To be honest, it's a bit boring to pick a bone in an egg. Xiong Yifang told us that Ghost can hover stably even under force five wind, but it's a pity that it's "sunny". Well, we should test it again next time.
Resistance to falls. If you can land smoothly, you can't test your fall resistance. But we should remind you to pay attention to the power, because it is not worth falling down when there is no power.
Supplement the unpacking photos
It is said that Lei Feng.com is the first media to independently test fly Yihang Ghost four axis aircraft without the guidance of official personnel. Maybe you want to see its packaging, then follow me to tear down the express box. We got the ordinary version, and Yihang also launched a version that supports aerial photography.
Xiong Yifang, the founder of Yihang Ghost, left a message on WeChat saying, "In a few days, we will send the machine evaluation of the aerial photography version to Leifeng. com. The aerial photography version supports the intelligent follow shooting function, that is, wherever the mobile phone goes, it will go. There are only three or five companies in the world that can do it, and we are the first in China.".
