Serpent is proud to announce the discharge of Serpent Viper 990e EVO 1/8 EP. The Serpent Viper 990E Evo is the successor of the profitable 990E.
We now have spent lots of testing and analysis to enhance the 990E. As within the 990 Evo Nitro automotive, we up to date the entrance and rear arms and added the flex shock mounts that are working so nicely within the Nitro automotive. After all we stored the excellent options of the 990E, just like the low weight, glorious weight distribution and ease of upkeep. An additional huge function is the bullet-proved, but very free transmission.
- Essentially the most seen new function are the brand new shock mounts. They provide the chance so as to add extra flex by eradicating the connecting carbon brackets. Additionally it is now doable to alter the shock angle on the inside mounting place in small 1mm steps
- The brand new entrance arms function a carbon downstop lever which provides a way more correct and constant downstop setting, a vital a part of the automotive’s setup.
- One other enchancment has come from the brand new bumper. It’s an aerodynamic enchancment, however as the identical time it provides extra help to the bodyshell. It is also much more immune to bending. All of that comes with a decreased weight by nearly 10g!!!
- A modified entrance one-way shaft permits a extra slender setting than previously. A entrance slender trackwidth is essential to have the ability to obtain on most tracks these days
- One other change to the arms (entrance and rear) is the additional 1mm adjustment in wheelbase. We discovered that in some circumstances the automotive is healthier with an extended wheelbase.
- After all the EVO nonetheless options the detachable inserts for the upright in addition to the steering blocks for tremendous straightforward upkeep. Within the EVO each inserts are centric, eccentric variations for further setup prospects can be found as choices
Basic options
- The ultra-narrow chassis is milled down to permit the bottom doable mounting of the batteries plate in addition to bettering the general flex traits.
- The central a part of the chassis options 3 NACA ducts for the cooling of the speedo in addition to the motor
- The motor has been put as little as doable by machining the chassis beneath it. This improves the centre of gravity in addition to the cooling from the underside.
- The rear of the chassis has a slot. This has turn out to be a vital function of the Nitro 990. It has to do with adjustable flex.
- It additionally carries 2 metal countersunk screws that act as a counterpart of the down-stop screws. This helps to maintain the down-stop extra correct and constant
- The general flex is managed by the “spine”, a highly regarded function of the 988E.
- The entrance of the automotive will be adjusted to extra flex by eradicating the two entrance screws and even the one on prime of the servosaver.
- The rear of the automotive can also be adjustable concerning the flex. The common rear finish options the confirmed, one-piece rear plate
- As an possibility additionally it is doable to make use of a softer rear finish utilizing an optionally available 2-piece rear plate
- The receiver and the steering servo are mounted on a small “radio plate” which will be simply eliminated for straightforward entry. The aluminium servo mounts are eccentric and will be mounted in 2 methods to regulate them to the model of servos.
- The rear finish includes a new design to permit an re-active toe-change in addition to keep away from any binding in any respect!
- By altering the place of the hyperlink the quantity of toe-gain underneath compression will be adjusted. The place proven is the “impartial” place.
- Because the higher hyperlink is changed by a suspension arm, we additionally modified the higher pivot on the upright. It’s now tremendous straightforward to regulate the proper camber.
- The peak of the pivot ball is adjustable by altering the aluminium insert. There are 3 positions
- The upright carries an aluminium insert the place the ball bearings of the wheel axle sit. In that manner we are able to obtain the proper roundness even underneath load to attain the least friction of the transmission doable. On this manner additionally it is very easy to take away the wheel axle/driveshaft for upkeep
- The entrance steering-block includes a related building. The aluminium insert provides the identical benefits as within the rear with improved drivetrain effectivity and improved ease of upkeep
- When the choice eccentric model is used, additionally it is doable to alter the roll-centre as nicely las utilizing a trailing or main set-up. After all the steering-blocks are nonetheless left/proper symmetrical and can be utilized with option1 in addition to option2 levers.
- The entrance higher suspension bracket now has an improved design takes offers a greater placement to keep away from camber or caster irregularities by utilizing bushings.
- The confirmed transmission is tremendous robust, but very mild and tremendous straightforward to keep up. The pulley of the mid-belt is sitting on a metal adapter that’s secured by a metal pin.
- The spur gear adapter is mounted with 2 of those pins. Altering the spur gear is tremendous straightforward, simply take away 3 screws
- The wire kind entrance anti-roll bar is ball raced. It’s straightforward to alter and alter as a result of open entrance finish design. The usual wire is 2.5mm and a couple of optionally available thicknesses can be found. The pivot ball hyperlink system directs the suspension motion to the bar and permits straightforward tweak adjustment.
- The lengthy sturdy entrance decrease wishbones are the open-style arms just like the 977. An aluminium shock mount plate is screwed onto the decrease wishbone. This enables the shock attachment level to be positioned additional outwards bettering shock movement. The entrance decrease arms are mounted to the entrance brackets with nylon holders. The package contains 2 variations: out and in. This technique additionally permits fast and straightforward entrance drive shaft upkeep. After all the 988 closed arms are usable as nicely
- The left and proper interchangeable higher arms are mounted with 3 place nylon suspension pin inserts. The three place inserts permit camber-change changes and are held in place by the anodized aluminium prime brackets. Under the highest brackets, spacers can be utilized to alter their angle or peak. Caster is adjusted with clips on the higher pivot pins. The identical clips are additionally used on the decrease pivot pins to alter wheelbase.
- The black anodized aluminium entrance axle has Japan made one-way bearings. Spring metal drive cups connect with the lengthy and skinny spring-steel drive shafts with CVD system. The ball raced spring metal wheel axles have aluminium quick-change levers. The open entrance finish design permits for very quick and straightforward removing of the entrance axle and driveline elements.
- The central mounted seervosaver permits straightforward and quick Ackermann adjustment. The servosaver includes a prime mounted insert which can be utilized in 3 positions. One other 2 Ackermann positions can be found on the steering blocks.
- The rear finish building with aluminium brackets is a really open design, which permits for straightforward of upkeep and cleansing. Dis-assembly requires the removing of just a few screws. Changing a belt if wanted, is a straightforward job. The eccentric bearing holders on the rear shaft permit adjustment of belt stress. The entire rear finish will be eliminated as one unit from the chassis by removing of just a few screws
- The wire kind rear anti-roll bar is ball raced. It’s mounted within the rear bearing blocks and is straightforward to alter and alter. The usual wire is 2.5mm and a couple of optionally available thicknesses can be found. The pivot ball hyperlink system directs the suspension motion to the bar and permits straightforward tweak adjustment.
- The slender strong rear axle in Serpent spring metal has a light-weight 9mm huge 48T pulley. Spring metal, CVD kind, drive shafts join the rear shaft to spring metal wheel-axles with aluminium quick-change levers. A really sturdy and lengthy lasting drivetrain.
- The rear floating physique mount which is mounted on the up-rights with 2 arms is centred by a carbon-fibre and metal guider. The mount has 4 positions on all sides to select from, relying on physique shell used and traction obtainable. The threaded holes on the tip of the physique mount give the choice so as to add additional body-support
