Description

The Serpent Viper 989 could be the latest growth of Serpent regarding 1/8 fuel market.
Serpent was the driving force for many years while the Viper 989 could be the latest interpretation of a top performance competition car according to that experience, combined with latest insights on weight, fat circulation and flex.
As the inventor associated with the Centax clutch, the 2-speed gearbox and lots of other items being now industry standard, we also incorporated some new solutions regarding suspension system.

Another major point of development was to reduce fat, reduced total of vibrations and easy set-up and maintenance.
Ultra-narrow chassis with improved flex characteristics. The framework is milled down in less load-stressed areas making it as light that you can whilst still being stay rigid in areas in which needed.
We kept the possibility to possess a weight inside very base which will be effortlessly adjustable inside it’s position.
at exactly the same time we improved the way in which it really is it mounted to reduce vibrations by utilizing a carbon fat connection which can be installed in anti-vibration rubbers.
We also have added 2 more areas for another weight, one underneath the motor and another one underneath the servosaver.

The central fat connection allows making use of max 3 loads

All loads are installed as low as feasible to boost the center of gravitiy
The one-piece plastic radiomount is changed by a 2-piece aluminium construction. It is lighter compared to synthetic one, and at the same time frame it improves the flex faculties while the precision of mounting the radioplate.
The back bulkheads are now also attached to the rearplate to boost the stiffness plus decrease vibrations.
The bulkheads are machined excessively for an ideal balance between weight and strength
Their shape now permits removing the rear solid axle without elimination of the 2-speed shaft and belt
The brake now features a 2.5mm thick disk with improved ventilation and stopping security

The pulley adapter is a much lighter construction for better inertia and improved acceleration
A new shorter interior gear ratio of 2.4 assists acceleration and escalates the active selection of the general gear ratio. Using 19/24 now could be just like 18/23 on 988.

additionally the overdrive changed somewhat to have the perfect rear/front drive balance with ENS and EFRA give fully out tires
New part belt tensioners improve clearance aided by the motor manifold.
it decreases vibrations regarding sidebelt.
Adjustment is easily done regarding midshaft
The new super-light midshaft set up additionally acts as adjustable gear tensioner along with pipe wire holder
The completely new gearbox has less inertia versus one from the 988. This improves acceleration.

Despite being lighter it includes brand new features to enhance reliability and consistanty
A much longer ramp for the roller avoiding locking associated with 2nd gear even with extortionate wear on the shoes
M4 setscrews for gap modification to simply help keeping the gap constant
2 bearings inside second gear “bell” for better truth of rotation and balance
Easy access for adjustment from the outside
2nd gear adapter is locked in position to avoid binding and deliver constant performance of motor and gearbox
New shaped fueltank attached to top of the radioplate.
The brand new tank is more consistent in adjustment no matter if it is full or very nearly empty.
The brand new tank seal keeps an increased pressure and keep things clean and dry
The limit associated with tank is higher allowing even faster refueling.
The number of the tank is 125cc and has to be adjusted by the user to master volume inside the guidelines through inserts
New superlight, one-piece bumper for improved aerodynamics.
No inserts any longer to keep it easy. Extortionate screening of various forms lead united states to this design to really have the most useful balance of front end grip on high and low rate and hairpins
New mounted rear framework stiffener to allow for easier removal of the radioplate
New method of mounting of this servosaver. In the event that radioplate just isn't mounted, the servosaver nevertheless stays in place
New shaped radioplate. This shape is found to deliver the best flex characteristics
New improved shockabsorbers for the ultimate hold

The solitary most important new function are probably the shock-absorbers. Plenty of attention has been payed to attenuate friction and jamming.
evaluating has additionally shown that a slightly smaller bore increases results.
on back associated with the car we also increased the total size for extra stroke and better progressivity
The piston is fixed onto the shaft with a nut. No clipses or shims.
On top of this we payed some awareness of the bottom seal. 2 X-rings and an extended bushing provide that additional little bit of low-friction sealing that keeps the oil inside additionally the dirt outside
As an alternative the 989 offers a heave-damper setup inside front side as well as the rear.
In because of this it is possible to alter heave changes pretty much independent of roll changes.
For instance you are able to have a really light roll damping coupled with a tremendously high heave damping, something is not possible with a classic suspension system.
The next damper may be used to just alter the damping faculties without a third spring, but in addition to incorporate a spring to improve springtime prices for heave
leading and rear heave sets can be obtained as an option.
