F2

Since the early 1980s, Tamiya has released several formula car models that are a faithful reproduction of the track racing world:

– Open-wheel Formula 1,
– Sport Prototypes with covered wheels and
– Endurance – covered-wheel endurance racing.

The reproduction of Formula 1 cars has always been important to Tamiya and they have always represented the cutting edge of technology available at the time.
To enable more people to start racing Formula 1 cars, Tamiya released the F2 chassis. In the real world Formula 2 is the gateway to the more performance oriented Formula 1, the best Formula 2 drivers have access to Formula 1 racing.
In the same way Tamiya sees Formula 2s as the models with which to start racing and practise chassis tuning. The F2 and F2 CS family coexists with the F1 and F1 CS family and represents the best compromise between cost and performance to start racing.
The commercial strategy is to introduce several models to the market that share the chassis and change the body. Technically there is continuous research: the latest model in this family receives a completely revised chassis that guarantees better performance named F2 CS where CS stands for Competition Special.
List of closely related Formula 2 models released for sale in the late 1970s and available until the mid-1980s:
– 58013 March 782 BMW, released for sale in 1979 and remained on sale until 1983; chassis F2
– 58014 Martini Mk.22 Renault, released for sale in 1979 and remained on sale until 1983; chassis F2

– 58030 Honda F2, released for sale in 1982 and remained on sale until 1986; chassis F2 CS

All of these models are factory fitted with a styrene body, which is heavier than a Lexan one, but richer in detail; noteworthy are the accuracy of construction for the March 782 BMW and Martini Mk 22 Renault model.

The main features of this family are:

– Central plastic electronics tray, this is a first for Tamiya. The electronics and battery tray is highlighted in orange in the picture.

– Plastic front bumper is different for the F2 and F2 CS release. For models 58013 March 782 BMW, 58014 Martini Mk.22 Renault and 58018 Ralt RT2 Hart 420R the bumper is in common with Porsche 935 Turbo model number 58002, Tyrrell P34 model number 58003, Lamborghini Countach LP500S model number 58005, Porsche Martini 936 Turbo model number 58006, Lamborghini Countach LP500S CS model number 58008 and Toyota Celica Turbo LB model number 58009.

– frame is central aluminium for the F2 highlighted in orange and FRP for the F2 CS  highlighted in green. FRP stands for ‘Fiber Reinforced Polymers’ and is a lighter material than the aluminium used for the F2. It is possible to replace the aluminium frame of the F2 with that of the F2 CS using accessory “FRP F2 Chassis” part number SP-1108.

– The front steering system is different for the F2 and F2 CS. On the left is the steering system of the F2 family and on the right the steering system of the F2 CS family.

The F2 family has a steering system consisting of a plastic shell containing the servo, the suspension arms and the two spindles. A very similar system that shares most of the parts is installed on the Porsche Martini 936 Turbo model number 58006 and Lamborghini Countach LP500S CS model number 58008. The spare part can be ordered under part number SP-1100 and the set of the two spindles, part number SP-1089, is also available.
The F2 CS family takes over the steering system from Golf Racing Group 2 model number 58025, Renault 5 model number 58026, Williams F1 FW07 model number 58019, J.P.S. Lotus 79 model number 58020.
Modification of the steering system to add shock absorbers.

– The motor and rear axle carrier system – motor – differential is different for the F2 and F2 CS releases. For models 58013 March 782 BMW, 58014 Martini Mk.22 Renault and 58018 Ralt RT2 Hart 420R the factory-installed motor is the RS380 with the option of using the 10- and 12-tooth double-sided pinion. For model 58030 Honda F2 the factory-installed motor is the higher-performance RS540. It is possible to install the RS540 motor on the F2 chassis by installing accessory SP-1103 or equivalent code 5103

– the wheels are rubber for the 58013 March 782 BMW, 58014 Martini Mk.22 Renault and 58018 Ralt RT2 Hart 420R. The wheels help absorb bumps by making up for the lack of a suspension system. The wheels are made of sponge in the Diplo release for the front wheels for 58030 Honda F2.
In conclusion, the evolution from F2 to F2 CS makes this family of formula cars very similar to the F1 and F1 CS chassis. The RS540 motor guarantees excellent performance, the FRP chassis is light and flexible enough to make up for the lack of suspension, and the Nylon steering system is very precise.
