Yes, we monitor the quality and reliability of all equipment. The first prototypes of all our products are being tested at our production facility. We have a load stand for strength tests, as well as UV and corrosion resistance tests. If we are satisfied with the prototype, then it is sent to our test pilots for practical tests. The most important parts are undergoing additional tests at ParAAvis company. Having chosen the best option for each product, we launch it into mass production.
