Unless you own one, you want one. Whether they are used for stunning aerial videos, recording special moments from a distinctive perspective, or race against friends; drones and particularly quadcopters are actually more popular than previously.
One of the problems I ran into in some of the first flights was individual motors cutting out seemingly arbitrarily. The quad uses 20A Turnigy MultiStar ESCs, and gives a decision between slow-down of motors, and hard cutoff when the voltage is low. This caused a lttle bit of frustration because the motors would start eliminating when the voltage was low, regardless of the setting via development card.
Meanwhile, the suggested regulations could mean a lot less red tape for those using drones for commercial use, such as making real real estate videos or inspecting structure sites. Instead of having to reapply at least each year for a certificate to travel drones commercially, it might get easier. The accelerometer tells us which way the quadrotor is accelerating. This 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 we can move it back and keep it hovering on a reliable position. One thing - each time you crash you will need to re-trim so just be conscious. Once you find the hang than it it's very controllable.
The manual is a mixture of hard-earned experience in the field, requirements under the FAA's Part 107 legislation, best quadcopter Under 200 practices for drone use, and methods that manned airplane pilots use to journey airplanes. It defines three assignments in each drone flight: The Pilot in Command line, the only real federally required role in the flight; the Observer; and the Journalist. The pilot is the sensible party under legislation. The observer will there be to share the pilot if something joined the area which is a concern. The journalist is there to ensure that what's needed for the storyline is being captured. A drone air travel can have all three of these roles, or perhaps the pilot. But that means the pilot is taking on extra work, which requires extra caution.
My upper rotor pins came up off after having a couple of days of soaring. What I have done is take off the whole bottom section where in fact the pins actually were. I QUICKLY soldered direct onto the material shaft and soldered on a large lump of solder. Using a small file I've filed down the lump of solder to form two metal forearms. You should use the link biceps and triceps to see approximately whereabouts the solder should go. I just proclaimed the positioning with a marker pen. This forms a really nice solution and on top of that it's steel. After reasslbling the helicopter flew flawlessly.
