Does Yuneec indicate a maximum wind speed that is deemed operable/safe for the 520 for tower inspections? This would be for AGL wind speed, and since most turbines provide wind readings it would be useful information for both parties involved. So how close is safe and at what wind rating...maybe too many variables for a clear answer. Has anyone performed an E90 vs E50 for inspection quality? I have seen others but not these two head to head. These two topics are closely related.
