Work is continuing on the AS2C, the electrical system is wired, the rear wheel is assembled and a lot of little things. The big one today is the pistons, a lot of people assemble the pistons before they attach the cylinders which can be complicated to line up correctly. The easiest way of doing it is to place the piston in the cylinder before attaching it to the connecting rods. You can see the entire process in the pictures below. The plastic bag on top of the cylinders and the paper down below is just there to make sure no small parts fall into the engine.
