Yes there is a lot of wires but for know until I feel comfortably it will be a necessary evil. Sensors are lipo voltage, rpm/speed, 3 temp sensors and RX voltage there is also a extra servo lead soldered onto the MMM throttle lead so I don't have to open the cover of the RX box to program the MMM. That Traxxas Slash box fit so well. We will see about the MMM BEC in a few months. There is so much snow up here doesn't leave many places to test.
