RadioLink Electronic Ltd www.radiolink.com turning. Same as ONE TO TWO mix control. 4. Dual Mix Control： As controlling dual-engine vehicles drive forward/backward and turn left/right, two mix controls at the same time are needed. RADIOLINK RC6GS has two programmable mix controls. Reverse Setup before Mix Control Setup Before setting the mix controls, please check if the reverses working correctly by testing its wheel and throttle.
RadioLink Electronic Ltd www.radiolink.com Hold RC4GS as the below pic. Normally, if turn the wheel right/clockwise, the left track should be moving forward while turn the wheel left/anticlockwise and the left track should be backward. Turn the wheel clockwise, the left track moves forward，the right track remains still If turning the wheel right and the right track moves backward; Or turning the wheel left and the right track moves forward, meaning the initial steering is reversed and needs to be set.
RadioLink Electronic Ltd www.radiolink.com Throttle mix steering setup completed, both tracks moves forward when pulling the throttle 2. Steering mix Throttle：Tracked vehicles turning left/right As tracked vehicles turning left/right is controlled by steering, steering leads throttle in the mix control.

RadioLink Electronic Ltd www.radiolink.com working unexpectedly. Then we can change to the ID.2 boat (or any other subsidiary ID boat preferred) and control it independently to rescue ID. 1 boat instead of controlling both boats at the same time, which makes the rescue more difficult. Unlike traditional binding mode, independent ID can easily realize rescuing stalled boat in the water caused by various reasons.
