Carrera wireless+ controller for digital 124

2.4 Ghz WIRELESS (WI) spare speed controller: for Carrera Digital 132 and Digital 124 with 2.4 GHz Technology. This separate WIRELESS+ controller is only suitable for Carrera Digital 132 and Digital 124 race tracks. It is a separate or spare WI controller (i.e. without cable) that fits on a charging station of the WI sets # 10109 WIRELESS+ set duo or # 10110 WIRELESS+ set single. This is basically a system of speed controllers without the well-known cable connection on the race track. The controllers work radiographically with a 2.4 GHz frequency. This gives you a range of up to 15 meters around the track wherever you are standing. So you can move freely. With a full lithium polymer battery you can drive for 8 hours and have a standby time of 120 days. Due to the 2.4 GHz frequency, there is no interference with the other controllers.
