If you don't own one, you want one. Whether they are being used for stunning aerial videos, acquiring special moments from a unique perspective, or rushing against friends; drones and specifically quadcopters are actually more popular than ever before.
One of the problems I ran into in a few of the first plane tickets was specific motors cutting out seemingly arbitrarily. The quad uses 20A Turnigy MultiStar ESCs, and provides a choice between slow-down of motors, and hard cutoff when the voltage is low. This brought on a little of frustration since the motors would start cutting out when the voltage was low, regardless of the setting via development card.
Meanwhile, the suggested regulations could indicate a lot less red tape for those using drones for commercial use, such as making real estate videos or inspecting structure sites. Rather than needing to reapply at least each year for a certificate to travel drones commercially, it might get a lot easier. The accelerometer tells us which way the quadrotor is accelerating. That is useful because we can get a concept of how much finished . has moved by looking at acceleration as time passes (position is mathematically represented as the double integral of acceleration) so that people can move it back and keep it hovering on a reliable position. One thing - whenever you crash you will need to re-trim so you need to be mindful. Once you have the hang from it it's very controllable.
The manual is a mixture of hard-earned experience in the field, requirements under the FAA's Part 107 regulations, guidelines for cheap drone for gopro (my company) use, and methods that manned aircraft pilots use to take a flight airplanes. It defines three jobs in each drone trip: The Pilot in Command, the only real federally required role in the journey; the Observer; and the Journalist. The pilot is the accountable party under legislation. The observer will there be to see the pilot if something joined the area which is a problem. The journalist is there to ensure that what's needed for the storyplot has been captured. A drone airline flight might have all three of the roles, or maybe the pilot. But which means the pilot is taking on extra work, which requires extra caution.
My upper rotor pins came up off after having a few days of soaring. What I have done is cut off the whole bottom level section where in fact the pins formerly were. I QUICKLY soldered straight onto the material shaft and simply soldered on a huge lump of solder. Using a little file I have submitted down the lump of solder to form two metal forearms. You should use the link arms to see around whereabouts the solder is going. I just designated the position with a marker pen. This forms a really nice solution and on top of that it's material. After reasslbling the helicopter flew flawlessly.
