am using it on several of my planes. i removed the connectors and replaced with whatever i use. its total weight is now 1 gram! i bench tested it and then field tested and have been using it with no problems. i programmed it for brake. i use it with the 6400 brick so i can program brake.
the only thing i would like to see is it with a higher lvc (3 volts would be good). the 2.6 it comes with is too low for the lithium cell (that's why i give it only 4 stars). what i do is the first flight i time it and fly it until the lvc cutt-off, and after that i bring the plane down 1 minute before, so the cell never again goes beyond a safe margin and this way lasts longer, as it does not go under 3 volts.
