I have now had 32 flights and in heavy fog, up to 60 kms an hour winds and max distance of 4383 metres as my longest distance from homepoint. I have flown in 2 degrees celsius and 25 degrees celsius. The total flying time is only 5hr and 29 mins but I just did a thorough examination of my drone and I found no evidence of any stress fractures!! My drone was purchased in early august but unsure if it has the new motors or old.
