Racing quadcopter with FPV for non-rubber budget - Robocat 270
Friday post prepared a copterov named Victor. He assembled and learned to fly a racing quadrocopter with online broadcast (FPV). Give the word to him:
Hello. Today we will talk about the racing quadrocopter Robocat 270 * . He came to me recently. When buying this quadcopter, I pursued two goals: to fly on FPV and not to bathe about all kinds of crashes.
I think you will not argue that every crash of our copters is another waste and weary expectations of details, and if the second is unavoidable, then I would like to save on waste.
')
So, what is this quadric. First of all, he hooked his style. There is something so beautiful in him, and not just a piece of carbon fiber tightened by bolts. I ordered it with Ebay in the “frame + brain + adjust + motors + props” variant. At the time of purchase, I already had control equipment, video transmitters, an FPV camera, and a battery. In short, for the quadric itself, I will pay $ 109 * . I think quite tempting price for such a quadric. If anyone interested seller on ebay gadgetextreme. The package arrived quite quickly, in a well-packed box.
So, first things first.
Specifications declared by the seller:
Motors MT2204 2300KV
Regulators SimonK 12A
Quadcopter frame.
The whole frame is carbon fiber, made in my opinion very high quality and accurate. The quadric beams are made of 3 mm carbon, which makes the frame really more resilient, the remaining parts are made of 1.5 mm carbon. Aluminum connecting bushings. In this frame, everything is perfectly designed for the location of the controller, video transmitter, camera, etc. Also, the upper part of the frame opens to access the internals of the quad and the controller settings. Very comfortably!
Controller.
Included was a CC3D controller. I did not know anything about him, because I flew all the time on the Naza. But, apparently, it's time to meet. Actually for FPV it is a great controller. A lot of different settings and a very nice software interface.
Engines and regulators.
Here, of course, it was not necessary to wait for special precision and quality. When setting up the controller pops up a menu with the setting of the motors, namely the "minimum motor speed." In other words, moving the slider from the leftmost point to the right, we must go to the point where the engine will start. So with these engines, this point is stretched by 10% of the slider. First, the engine begins to twitch ... and only then, when we add enough power, it starts, and at a speed that is almost enough for takeoff.
I put something in between a jerk and a launch. As a result, when you start a copter, it happens that not all engines start at once, some jerk. But I solve this problem with a small “re-gas station” and they start. In short, for this money is a small problem. The main thing that flies.
Propellers
This kit came with carbon fiber propellers. The only thing I would like to mention here is almost perfect balancing and workmanship. Understanding that on this quad I will break more than one set of props, I decided to order a few more plastic sets on a hobby-binge. And of course, after flying on large Copters, I was very pleased with the price of propellers: 69 rubles per pair (without delivery). So it is very budget.
Fee wiring power.
Regarding this board, I will say how to handle it (sequentially) - the package arrives, we get the board, open the trash can, throw out the board. Actually, she worked for me for 15 minutes and that was all ... more, the copter showed no signs of life. I had to disassemble everything, throw it out and collect everything in the old fashioned way on twisting. So, when buying such a quadric, use another one or do everything on twists.
PS You can also buy an additional such board * (this is the bottom board of a quadric with power distribution). But consider if it cracks, the quadric will not fly away.
First flights.
I completed this quadcopter with the following "details":
1. Camera for FPV * at 700tvl.
2. Video receiver and transmitter * at 200 mw 5.8 ghz with clovers. Remained from previous models. In the future I plan to buy something normal, since with a stated distance of 2 km, they work with clovers for a maximum of 200-250 m. Therefore, if you take something like that, take 1000m to 2000 and then.
3. Control equipment for my turnigy 9xr with the Frsky DJT module. on foot-foots, etc. I didn’t fly because there is nothing to compare with, but I like:
4. Well, and glasses. In fact, their choice is a separate topic, as there are many options, they are expensive, and there is no way to touch them. Once I flew with a friend in the first Fatsharks. It seemed to like it, but I did not remember long ago. And they cost at least 20 thousand rubles. Not having the desire to spend so much money, I stopped at the FPV helmet Quanum DIY goggle V2 . The video helmet is a case in which a 5-inch screen and a Frenkel lens are installed. It is a great replacement points, taking into account the fact that it costs essentially 4 thousand rubles. I took the version number 2, because in it there is a “cover” into which the whole “box” is inserted and all this is put on the head.
Now about the flights.
The behavior of a quadric is quite predictable (and this is good). Even on the default settings of the fakes, he behaves very quickly. In addition, I thought the cap, installed on the copter, will break on the first fall, but no, it keeps strikes quite well, etc.
The flight time in mixed mode was 9 minutes 30 seconds. At a temperature of 6-7 degrees. Pp. With zippy 3s 2200mah 25c battery. I am glad that the FPV camera in low light goes into the "night vision" mode. That is, roughly speaking, you can fly in the dark and see the picture at a distance of 2-3 meters.
Well, the lights of the copter, it is not very clever. I just bought a piece of LED tape and will soon be testing quadrics for night flights and scare passersby. :) In general, a very interesting and fast animal!
I also suggest that you watch the test flight overview video:
Conclusion.
If you are thinking about buying a FPV quadric, but you have a non-rubber budget, then the Robocat 270 * is for you. Excellent in its characteristics, and attractive in appearance. Really deliver a lot of positive emotions from flying).
