With all the items ready, construction can begin. The front suspension assemblies comprise moulded plastic arms and various metal parts, and at the rear comes the motor and gearbox. True to the original model there is no differential, but there is a choice of gear ratio. The rear suspension arms are also plastic and mount to the cast alloy gearbox. The hub carriers and gear shafts run in bronze bushes, but these are prone to wear and also create quite a lot of friction, so 1 replaced them with ballraces. I was lucky enough to have these already from another Tamiya model, but they can be bought from a model shop if you want to add them too. The ball-races are far smoother running and allow the car to run faster and help the battery last longer. A 'U' section aluminium rail fits between the front and rear end which acts as a battery tray and mounting for the receiver and speed controller, as can be seen in the photos. Suspension is of the torsion bar type, and here is one of the very few changes for the new model - the torsion bars are now metal as opposed to plastic ones in the original. One important point with radio-controlled cars is to keep the wiring as short and tidy as possible, as this reduces the chances of interference and it also looks better. It's also a good idea to wrap small plastic bags around the receiver if there's a possibility of it getting wet, as water and delicate electronics do not mix!
