Serpent Viper 977-EVO
1/8 scale gas onroad car

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 continiuous 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.  

Bodymount rear

Rear floating bodymount
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


Front bumper with inserts
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.

Central flex

Aluminium central flex system with bearings
The system consist 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.


Aluminium chassisplate  in 7075 T6 with optimised flex and weights slide
The chassisplate 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.

New geometry  with narrower front end
The narrower chassis in front allows to run a slighly different geometry in the front.


Centax hardcoated alu clutch gears with 0.9 pitch
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.

Key new features
-   2-speed gearbox  SL8 XLi with superlow inertia
-   Composite 2-speed gears with 0.9 pitch
-   Centax hardcoated alu clutch gears with 0.9 pitch

General overview

General Features:

5mm aluminium chassis  in perfect  symmetrical shape for even flex and weight distribution. Aerospace quality 7075 T6 aluminium with engraved logo. Improved stiffness around the engine for better engine performance. Countersunk holes, chamfered edges for more cornering,  ground clearance.   Space in center part of the chassis to allow mounting of brass sliding weights, which are used as set-up tool, to play with chassis balance.  This has big influence on steering, grip and tyre wear  and is very easy and quick to change. All screws from the bottom are with 2.5mm allen size.

The strong aerodynamic shaped  composite bumper. The upward edges make it more stabile, so these wont touch the surface under impact or with high temperatures.  As extra feature offers removable inserts.  Its very easy and quick to test with or without inserts in a matter of seconds

The durable composite front bodyposts are excentric ,  to allow moving the body to front  or back a   few mm to optimize steering / downforce.

The steeringblock , which can be mounted left or right,  offers a system to change the axle position more to front or back giving a “trailing” or “leading” steering, and the ability to change the kingpin-inclination and offset.  The steeringblock features an aluminum plate to connect the steering-rods, 2 options for Ackermann.

The spring-steel steering-rods are fastened to the alu steeringplates, which mount to the new steeringblocks.  Optional carbon fibre disks can be mounted on the side of the uprights to stiffen the assembly and for aerodynamic reasons.

The long durable front lower wishbones, are mounted superlow in the car, and  feature  a semi covered “leg”  for the inner suspension pin and the pivot link for the front anti-roll bar system, its also has an extension for the down-stop screw . The lower arms hold the lower alu shockmount plate, which allows a further out and higher mounting point for the front shocks.  The strong  upper arms in  can be used left and right.  The front lower arms connect to the alu front bracket on very low  nylon holders. The kit includes 2 versions, wide and narrow .   This whole system also enables you to replace a front driveshafts very quick and easy.

The longer upper arms are mounted between the anodized aluminum top brackets, which also hold the suspensionpin inserts to allow camber-change adjustments with 3 possible inserts . Below the alu top-brackets spacers can be used to change angle or height. Caster spacers are used as simple clips on the upper pivot pins.  Same clips are also used on the lower pins to change wheelbase.

The topmounted composite bracket gives extra stiffnes to the front section, it holds the 3mm thick carbon fibre front shocktower and allow for the down-stop screws.

The ballraced front anti-roll bar is a wire type, with very easy and fast open access on the front, captured in the alu front braces.  The standard wire is 2.5mm and 2 other as options. The pivotballs link system directs the power to the bar in a smooth way and easy to adjust the tweak with the captured pivotball.

In the front the alu front axle with Japan-made  one-way bearings features now an improved pully assembly, free of play and super-true.  Springsteel drivecups, strong, long and thin spring-steel driveshafts with CVD system, and ballraced springsteel wheelaxles with alu quick-change levers. The open front end design allows for very fast and easy removal of the front axle or parts.

The springloaded servo-saver allows easy and fast Ackermann settings.  The servo-saver features a top mounted insert which can be used in 3 positions.  Another 2 Ackermann positions on the steeringblocks.

The steeringblocks   and rear uprights connect to the arms with springsteel 8.5mm pivotballs , which run very smooth and well protected in nylon cups, and are easy to adjust with an allen  tool.

2.5mm carbon fibre radioplate  with the the center  flex-control system. The radioplate holds the fueltank, the receiver battery and  the integrated electronics bracket/box, as well as the center flex system

The new center flex system consist of a lower and upper CNC machined aluminium bracket and a smal carbon brace.  The upper one is fixed to the radioplate and the lower one to the center radioplate mount.
In rigid standard positon the upper and lower brackets are mounted fixed with 2 screws.  
In the flex position the 2 bearings are in place and with the 2 screws dis-assembled, offer the central chassis flex.

Compact composite brace and box  in one, which holds and protects the receiver and mounts both servo’s, which both lay on their sides, as low as possible, just a small clearance to allow for chassis flex.  The cap of the receiverbox  offers a unique yet simple and safe holder for the cable connectors of the receiver, which works as a simple switch and is very accessible.
The optional carbon transponder brace mounts to the integrated electronics brace.  When using a small receiver, the box has space to hold the transponder too, but must be tested for function before the race.  In our test it worked.

Low 125ccm fueltank in a long and narrow design, with a premounted bronze filter. The narrow tank will ensure a better fuel-supply to the engine, as the fuel can move less from side to side. The labyrinth  inside the fueltank will  also keep the  fuel more stabile and avoids foaming. The tank also has elevated sections in the front, which make sure the fuel stays close to the filter when the tank is amlost empty. This creates like a warning signal  a few seconds before the tank goes fully empty, so you can try to find a safer place to park.  The fueltank has a strong  springloaded cap and silicone rubber shaped seal, and has a connection for the pressure line.   The inner bottom   of the tank allows for mounting inserts to reduce volume if needed.

The composite nylon radioplate bracket, holds the rear part of the radioplate and the strong chromed angled roll-bar, and also mounts the adjustable ballraced belt-tensioner. An aluminum one is optional.

The majority of the  topmounted screws are in allen 2.0mm size, except for the upper suspension brackets in 2.5mm.

The batteryholder  between the tank and side belt , is made to fit the more common Lipo packs. There is also enough space to fit a regular batterypack. The holder incorporates an easy spacing system to allow this.

The light, hollow 8mm hardcoated aluminium middle shaft is kept rigidly in place a small, low placed and light alu holder, which also holds the spring-type exhaust-wire.

The final drive ratio of the car is 2.286  
28T front pulley
18T mid-inner pulley
25T mid-outer  pulley
19T outer lay-shaft pulley
21T inner layshaft pulley
48T rear axle pulley.  

All the superround and true pullies have holes in the side flanges to allow dirt and dust to move out easier.  The 977 has the latest pullies, with more teeth, so larger diameter which makes the belts run smoother, with less friction.

The belts are low friction type  as standard, rear one as 8mm, side in 6mm and front 6mm too.  The adjustable ballraced belt-tensioner ( carbon, alu) keeps the sidebelt running smooth.

The low seated anodized aluminum engine mounts keep the engine well positioned and aligned  and transfer heat to the chassis in the best way.

The rear end construction with the alu brackets  holds the brake and rear axle. Its open design allows for eas of maintenance and cleaning, and needs very few screws to dis-assemble. Replacing a belt in case needed, is simple and very fast too. The excenter on the rear shaft allows for belt tensioning.  The whole rear end can be removed as one unit from the chassis, with very few screws.  

The rear axle sits very low in the car, to achieve more mechanical grip.

The brake is on the rear axle, next to the solid axle pully.  This reduces the inertia effect of the brakedisc a lot because the rear axle spins much slower than the twospeed shaft.  Also the brake-stress on the rear belt  is almost gone.  It’s a very compact system and well protected against dirt, but still open enough to allow for sufficient coolng.  The swimming ventilated brake-disk rotates on the rear axle and the springloaded cam-operated   brake pads will provide all the stopping power you may need. The race brake pad material is baked on strong steel plates and allows very precise braking with lots of brake-feel / feedback.  Instead of a cable we opted for the well-proven wire-linkage of all Serpent cars.
The ballraced brake activator is bolted in a light alu holder to the right rear bracket.

The ballraced rear anti-roll bar mount in steel adaptors, which run in nylon spacers in the alu holders as integral part of the rear brackets, with 2.5mm as standard wire and 2 other as options. The anti-roll bar links to the rear lower arms with adjustable trackrod guidance.

The solid rear axle with lightweight 48T pulley in Serpent springsteel, 9mm wide with 4 slots for the pin.

The aluminium rear brackets and the 2-speed layshaft holders have small ears which allow for mounting of the optional alu or rubber spacer, to control flex.  Either full flex, no spacer, or some flex with rubber spacer, or zero flex with the aluminium spacer.  
The suspension bracket and rear plate hold the pins firmly and have composite roll-center inserts to allow for fast and precise changes.

In the rear strong springsteel driveshafts , springsteel wheel-axles  with alu quick-change levers and a springsteel rear axle.  Very durable and lasting drivetrain

The long durable rear lower wishbones  can be used left and right. The lower rear arm holds the low mounted  link for the  rear anti-roll bar and holds  the  alu mounting plate of the rear shocks, which allows a position which is very far to the rear and to the outside for best performance/ geometry.   The lower arms also hold the easily accessible down-stop screws. Nylon clips are  used on the  lower rear pins to change wheelbase.

The durable composite uprights hold the ballraced spring steel wheelaxles, with aluminium quick-change levers.  The 8.5mm piotballs are used to adjust camber  fast and easy with the smooth hex-shaped plugs . The arms of the floating bodymount mount to the top of the uprights.    On top of the up-right spacers can be added under the pivotball to change rollcenter and camberchange.  
Optional carbon fibre disks can be mounted on the side of the uprights to stiffen the assembly and for aerodynamic reasons.

The adjustable rear upper camber links mount to the  rear carbon camberplate with 2 positions .

The rear floating bodymount is mounted on the up-rights with 2 arms and held in place by a carbon-fibre-steel guider.  The mount  has 4 positions each side to choose from, depending on body In use.  The end of the mount allow for mounting body-supports , with full threading to allow exact positioning. The system  leads the available downforce direct onto to the uprights to the tyres.

2-speed gearbox  SL8 XLi with superlow inertia
All the parts of the gearbox have been made smaller and as  light as possible, still keeping durability on top of the list.   The gears changed to a 0.9 pitch which is smoother than the  original one.  The Serpent gearbox system was our innovation in the late 80-ties and the system hardly changed, only optimised, and now as system in use with all other brands .

Composite 2-speed gears with 0.9 pitch
Smaller lighter gears and with 0.9 pitch for smoothness and performance.  The precision machined and hardcoated gears are durable and smooth.

The innovative Serpent  True Motion Centax clutch is fitted.  Serpent as inventor of the original centax clutch, has  developed the clutch over the years and the current version excels in power throughput , reliability and eas of setting.   The standard version comes with a steel clutch bell, red centax show  and hard anodized clutch-gears.

The kit features high speed ballbearings, mostly sealed ones with aeroshell lubrication or grease.  All bearings in the car ( except for the servosaver and brakecam) are seated in nylon bushings to reduce  vibrations and play.  

The shockabsorbers are the latest Serpent RCM  units with membrames. The threaded houses with setting-nuts ( o-ring inside) makes ride height changes easy and precise.    The RCM shocks are very smooth, and easy to assemble and fill.  The shocksprings  are selected, matched,  flatgrinded, colorcoded units, equal length front and rear.  

The kit does not include engine-pipe, airfilter, body, tyres-wheels or electronics.
The silicone shockoil , silicone fuelline and pressure line  is included.

The 977-evo comes with a full color assembly manual Online as PDF , reference guide and exploded views all in one.  Set-up sheets  ( blank and default) are ready to download seperately, and 2 decalsheets are included in the box .
