Short and sweet........the track mode does not work.Tried it in "Follow" and "Orbit" modes and it would track for about 50-100 yards in the open desert and then would say or read that it lost confidence in object or something of the like and stopped tracking.In orbit it would orbit 2-5 circles and then lose object all in the wide open desert.I was tracking a Polaris RZR driving about 15 mph in follow mode and sitting still in orbit mode.Gonna see if I can get my $25 back.Very disapointed.One other thing.......I could never initiate RTH in Litchi unless I shut my controller off.My phone is a Galaxy S5.
