V3.1M – Standard kit (4-Channel, 6 LED cables)


This set can be used with or without the MFC. This set also has the advantage that several Slave units can work with the Master. (handy to take a trailer from someone else in case of a breakdown: D) This requires a one-off link to the other Slave. You can use a LIPO battery together with a BEC. Furthermore, all functions that MFC has are also included here. Handy if you don’t want or don’t have an MFC.

Included are 6 LED cables, the main unit supports up to 12 LED cables. Install on Semi Truck, internal Bluetooth wireless connects with V3.1S (V3.1s unit separately available).
