I have been flying helicopters for 2 years, I took the quadric purely to try. It is controlled by an order of magnitude easier than a helicopter, spare parts cost nothing compared to align, you can hit it in the wall five times a day. The remote control is more like a toy, there are no settings, you canβt even set limits. Radio path - range out of the box 20 meters, then either it falls or flies away. I strongly recommend that you disassemble both the remote control and the quad before flying and watch videos on YouTube, replace the antennas. The antenna from the wifi router easily gets on the remote control. Soldering for 3 minutes. The power connector and the quad must be glued to the glue, otherwise it falls out. Do not take the camera, it is better to take the fpv kit on it, it writes to the SD card and transmits the image to the monitor. I repeat once again, do not fly without replacing antennas, the probability of losing a quad is 90 percent. For flights during the day, stick green and red electrical tape, the diodes are not visible during the day, otherwise you will lose your orientation. Falls are not terrible, light and durable and spare parts for $ 3. Ali is like dirt. I recommend a quad for learning and making a decision about buying a phantom or cx20. It flies very nicely, the wind does not hold, it sits down smoothly when discharged.
