Exactly the same for me. Got the kit back from Yuneec UK, who replaced the faulty E90 and the upload works a treat. Currently only using this as a record of flight dates and times but I shall definitely explore the uploads from the airframe once I do some more flights (weather on the south coast has not been good).I have my drone back, and Yuneec UK replaced the E90 camera. Took it all out yesterday and I was mightily impressed with the H520. Very stable, and flies straight and true even with a stiff crosswind.
Got back to the office and put my login for DroneLogBook into the settings, pressed upload and it just worked. No hassle at all. Had a look at the information they brought into DroneLogBook. Anybody any idea what the logs from the airframe would provide in addition to the ones on the ST16s?
