Cool video, wish I had the money to buy one of those maybe. Back to what I think is probably 4WD-101 class, and this could probably use a new thread but since it is mentioned here with regards to the GU8... They mention the diff lock so does that mean that both front of both rear wheels spin at the same rate, so one cannot spin faster than the other, hence they are 'locked'? But then, isn't that what 4WD mode does anyway? Or does 4WD mode simply allow all 4 wheels to receive power from the engine instead of the just 2 of them? If so, why do you need to change direction for 1m so that your axles are no longer locked when getting out of 4WD mode? As you can see, I'm a little confused haha.
