I just bought an H520E from the US Yuneec website. I sure hope the problems I have been reading about have been corrected before shipment of new units. My drone is still with UPS, getting it Thursday.Interesting...
I am a Commercial Yuneec dealer... have already sold some H520E /RTK and have not been contacted by Yuneec regarding an upgrade.
Thermal camera modifications.What are the Thermal Modes that you mention? My new H520E arrives on Thursday of this week.
Here is the original thread for that.What are the Thermal Modes that you mention? My new H520E arrives on Thursday of this week.
Yes, that's about the only way I can see about asking.I would send an email to the address you quoted in your post and ask them. There should be a range of Product ID’s affected. When, where, and from whom did you purchase your H520E?
I put about 30 on ours after the replacement before I noticed but I'm pretty sure I caught it on the flight that it happened on because you can feel that it melted and is harder to get out. I reluctantly ran another battery and it was fine. The connector was not hot at all. I finished the mission with two more batteries and the last one did it again. I also noticed that the two batteries that burnt had a small gap between the cases and the underside of the connector... I am starting to have the felling that it could be just as much if not more on the battery/connector side. We already know the +/- are too close to each other but there should not be that much heat being generated unless there is a short or the wiring and connections are too small to handle the bursts of consumption. I am supposed to be getting a replacement unit so we'll see how it goes.got about 12 flights on the h520e rtk that has the new subframe so far I have no issues with the flight battery heads.
Or admit the new style connector is a bomb and go back to the Dean’s style connector that has worked for years in the other H series aircraft.I am thinking the new subframe did not address the entire vibration issue. the connector head itself has no antivibration quality the battery pins on the drone side may still be subject to fine vibration that may lead to failure. the only way is to make the frame a complete 2 piece unit with antivibration damper between the entire frame that holds the mainboard and the complete frame the houses only the battery including the battery plug.
I think it may have been discussed when you had it changed to the Deans style, but can you adjust your low voltage warning points to accommodate the lower voltage batteries!? Or do you find that to be unnecessary?well I need to shake out the h520e that I had them place the deans connector and see if those battery heads get damaged or loosen at the plug.
