Miscellaneous | Tamiya McLaren MP4/6 F1 R/C Car

In 1995, I bought myself a McLaren MP4/6 F1 radio-controlled (R/C) car (Tamiya). The car itself is based on the (now obsolote) F102 chassis, with a rear ball-bearing differential, a single rear damper suspension for smoother cornering, and two small front spring suspensions. The current comes from a 7.2 NiCd battery, feeding into a servo for steering and an electronic speed controller that moderates the current to the electric engine (standard 540 type). The transmitter is a Graupner standard D4-SSM40 JR remote control unit (2 channels). Nice detail, the driver sitting in the car is the famous yellow-helmet-wearing Ayrton Senna, also known as God's right foot.

In the meantime, several Hop-Up Options have been installed, such as an aluminium front servo torque, a rear aluminium motor mount to dissipate the engine's heath (which really gets quite hot), complete ball-bearings on all axles, a different gearing system (Spur gear with accompanying pinion gears), and rubber packers on the front suspension to increase the frontal driving height.

The underplate hovers approximately 3 mm above the ground, and the car itself can achieve over 60 km/h depending on which gears are used.

Below are some photographs; you can see the car's spunge tyres, as well as the interior of the car when stripped of its Lexan body casing. This shows the steering servo sitting in front, connected to the wheels. Right behind this servo sits the R/C receiver, followed by the red-coloured electronic speed controller. The main center of mass is located at the battery and the engine block, on top of which is a blue rear damper installed.
