Lego McLaren MCL35M (2021 Italian GP first and second place) - Bags 1

The kit was given to me by my daughter and son-in-law as a thank you for letting them stay with us while they were between houses.

The full kit

Here it is, unboxed, and ready for assembly to begin. There are 1432 pieces to provide a model car 13 cm high x 65 cm long.

As usual (I've only done a few, but I doubt they differ that much), there are a number of bags, and multiple bags will have the same number.  So I start by opening each bag and putting the small pieces in trays (old take away containers), and arranging the larger pieces, so they are easily found.

The first part to be assembled is the differential:

This is a reasonable working model of a differential (no lubricants involved) and allows the wheels to turn at different speeds.

Next it is placed on a frame and some suspension added:

 Then the engine is assembled:

The engine has 6 cylinders and pistons that move when it is turned over.  All very impressive as this is all hidden inside the car.  But where is the gear box?
