You can rely on it - because this is exactly what we are doing. All products which successfully passed the Yuneec Certification Program have undergone a comprehensive testing program at Yuneec Software & Services in Zurich. This makes us so sure that the H520 continues to function properly if the accessories are used with it. For many pilots, the H520 is a working tool. A tool that accompanies and supports them in their daily job. That makes it even more important to use only original accessories or Yuneec certified accessories. This ensures that you receive the full warranty coverage for your H520.
