The update should be performed with the Firmwareupgrader >

This receiver has only one (red) LED


After the update a factory reset should be performed!
Push and hold the Bind-button then switch the receiver ON and wait about 3 seconds until the LED light up.
Release the button. Without reset the servos might run to their mechanical end point!

A beta version of a program is an unfinished version that has already passed the alpha stage. Although the program can be used in its basic functions, it has not yet been fully tested for errors. This means that using the beta may cause crashes or bugs.
