advice needed. . .my first purchase was returned to sender because it was not controllable, no problem. i looked for maybe a better one and ended up at the same supplier who advertise "NEW" in open box for an additional 150$ or so. after my 7 day wait, i did what all the videos said to prep for maiden flight. batterys charged full, sim card in the camera, calibrate the compass and satellite thing. . . the camera rotated and tilted and the landing legs functioned as one would expect but even with 15 acquired satellites in the controller the craft was still trying to acquire. i let it sit outside in the field away from everything for 15 minutes and it still had none listed for the craft and did have 17 for the controller. i attempted to contact the seller and he takes no messages except if i want to return it. Yuneec asked for a serial number which i found on the machine yet the message to yuneec would not transmit. i looked at the box the craft was shipped in, and there was a tag attached saying "new" and a serial number tag. . . the number was not the same as was on the crafts tag. . . im becoming suspect here. so the question is, what am i missing in my set-up to fly ? im *** near 80 and running out of saturdays and patients. quite disappointed to say the least. any suggestions ?
