Dankoni Must to admit that cracking sound is maybe normal thing at the end. May be that suspicious sound comes from motor magnets. It is working well after a while. Fantastic!!!

BG564816401 That is perfectly normal, because there isn’t a center differential. When you spin both front or both rear wheels in the same direction, you’re causing the prop shaft (center shaft) to spin, which causes the motor to spin. What you’re feeling is the magnets of the motor as the shaft turns and changes from one magnet to the next. When you pull the throttle on your transmitter, the opposite happens — the ESC sends signals to the motor’s magnets, which cause the shaft to spin, which then causes the prop shaft to spin via the gears, which then causes the wheels to spin via the diffs.
