Viper 977 EVO 1/8 GP 4wd 2013-2014 IFMAR TQ and World Champion, Japan Tadahiko Sahashi with Viper 977 Gas powered top level racecar with 4wd, belt-drive, Centax true motion clutch, XLi8 gearbox, flex-system front and rear, brake on rear axle, front one-ways, rear solid axle, ballraced anti-rollbars. A fully adjustable race chassis to the latest spec and technology. Lighter, stronger, new geometry, more tuning features. Design by Michael Salven.

Serpent has been developing 1/8 scale onroad rc cars since 1977, officially as company since roughly 1980. That is over 35 years of of race and development experience combined!

The Serpent Viper-EVO is the next step in the continuous development of this very demanding 1/8 scale racing class, the pinnacle of rc car racing. The Viper 977-EVO is all about refinement, to make a superb car even better. Ready to defend the 2013-2014 World Championship TQ and title by Tadahiko Sahashi from Japan.

Extra ribs and more material is added to increase the stiffness of the rear bodymount and a 4th hole is added both sides for more tuning options

The newly developed front aero type bumper is a very durable unit, which as extra feature offers removable inserts. Its very easy and quick to test with or without inserts in a matter of seconds.

Aluminium central flex system with bearings consists of a lower and upper anodised aluminium section, connected with screws for zero flex, or with bearings inside for some controlled flex. It needs removal of only 2 screws to go from fixed to controlled flex.

Carbon fibre 2.5mm radioplate with aluminium mid-flex system. The stiff carbon fibre radioplate is one piece again with the flex system moving to the center of the car, just behind the tank.

The chassis plate is a very important part as central unit in the car. The flex-characteristic is a major point, as well as weight balance with the sliders we apply and the dissipation of heat from the engine. The chassis is narrower in the front to allow a slightly different geometry. 2 sets of front lower pivotpins holders are included to change the geometry, run it narrow or wide. Machining of the chassis allows flex in a different area as before, and can be influenced by using the carbon brace.

To go with the 0.9 pitch gears, the Centax gearpinions also needed to go to the 0.9 pitch. The precision machined and hardcoated gears are durable and smooth. The Centax clutch is a Serpent innovation from the early nineties, and is in use by almost all brands now.
