Has anyone using the Flytrex LIVE 3G tracker had to deal with their customer support? After installing it with the Installation Adapter, it wouldn't activate. I used SIMs from AT&T, Verizon and H2O. With the time zones, it took a week of e-mail back and forth to their technical support in Israel for them to determine it was defective and they authorized a replacement. But, they wouldn't cross-ship, they had to receive the defective unit first. Any type of express shipping to Israel was more than $70, so I sent it USPS "First-Class Package International Service". That took two weeks to get it delivered, but they received it last Monday (July 25th.) Since then I have not heard anything from them, and they have not returned my e-mail messages. I guess they are still using the old DJI customer service model! My experience with DJI was great, they had my cracked shell repaired and back to me in a week! In the meantime, I discovered that the aircraft won't fly with the Installation Adapter in place, but the Live 3G unit not attached to it. It seems to startup normally, but when starting the motors, the error "Warning, IMU Initializing. Do not move aircraft until initialization is complete."
