Quadrocopter - not a model, almost all have to buy - Motors, stroke regulators, controller, batteries, you need to build only a frame for all this, and it's easy, if only it was even and solid.
For the frame, as always, I bought everything in the building shop and found it on the corners. I will show a small photo report on the construction.
We take a square aluminum profile, a corner, a strip, a food container, a piece of textolite, cog-screws and proceed.
We cut the profile to connect the crosswise.
We attach the pad and textolite.
On the template, beautifully bend the strip under the legs. As it turned out later, the legs with a rough landing sometimes bend, then with a confident hand straighten out - and the whole repair. Maybe it was not worth it to bend them so neatly, but you must have some kind of original look.
We fasten the legs.
Installing motors
We fix the lid from the food container, install the controller, the stroke regulators, the receiver, using color tape to add color, so you can see where the front, where the opposite.
Bottom screw the pad for batteries, we close the electronics food container.
Install the screws and all.
Actually after that, the settings, calibration, the first flights, the understanding that you do not fly, and the son does it perfectly. Well, not everyone is born to fly. And then, when you already build a new hexakopter, this quadrocopter can be equipped with a suit with illumination and entertained friends and spectators in the evening on an airplane show.
