Thanks for the responses. I have already tried all the suggestions. I am unable to find a YUNCGOETUS anywhere for sale including eBay, Amazon, BHPhotoVideo, Vertigo Drones, Carolina Dronz or Crutchfield. I have even tried to find a used/refurb unit without success. I also asked Yuneec if the EU version (YUNCGOETEU) would work with a US-based/purchased aircraft and they indicated the firmware is different. I would think it would be easier to update/replace the EU firmware with US firmware than to hack an H520. I wish Yuneec had given these cameras a different model name as this leads to a lot of confusion and misinformation. As a small business it is difficult to justify purchase of a new aircraft just to get the thermal camera as I already operate 2 H's. The cost of the camera is steep enough without adding the cost of another airframe as well which make the H Plus option less desirable for this same reason. If anyone has other ideas or finds availability please post to this thread. If I had the financial/design resources I might pursue an aftermarket offering for an H thermal cam... I'm sure there is a growing market and other operators in the same position.. but then if I could afford to do that I could just purchase and H520 ;o}
