Although the Viper 977-e is based on the Viper 977, it has a lot of features that make it a dedicated Electric racing car
2 belt system with 5mm wide belts for optimized effectivity. Both belts have ball raced belt-tensioners.
5mm stiff aluminum chassis in perfect symmetrical shape for even flex and weight distribution. Countersunk holes, chamfered edges for more cornering, ground clearance. All screws from the bottom are with 2.5mm Allen size. Many pockets in the chassis to make it very light but still stiff. As optional the full carbon chassis can be used which weighs around 90 grams less.
2.5mm carbon fiber top-deck to create a strong and stiff connection between the fronts and rear-end of the car. The servo is mounted in the center of the car and can hold large and low profile servos. The center offers also space for the receiver which can be glued to the small plate/ clips.
Strong carbon fiber battery holders, which can be easily adjusted to fit most popular 2S or 3S battery packs. The batteries can be moved more to the front or the back with the flexible mounting system. This can be used to change the balance of the car, to create more steering or grip. The low and central position of the batteries creates the lowest and best possible CG.
Strong carbon fiber speedo plate, which fits most popular speedo’s well. The plate with speedo attached can be easily removed.
The durable alu front body posts are eccentric, to allow moving the body to front or back a few mm to optimize steering / downforce.
The steering block, 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 spring-steel steering-rods are fastened to the aluminum steering plates, which mount to the new steering blocks. Optional carbon fiber disks can be mounted on the side of the steering blocks to stiffen the assembly and for aerodynamic reasons.
The steering block is right and left the same, and features an aluminum plate to connect the steering-rods, 2 options for Ackermann.
The steering blocks and rear uprights connect to the arms with spring steel 8.5mm pivot balls, which run very smooth and well protected in nylon cups, and are easy to adjust with an Allen tool.
The ball raced front anti-roll bar is a wire type, with very easy and fast open access on the front, captured in the aluminum front braces. The standard wire is 2.5mm and 2 other as options. The pivot balls link system directs the power to the bar in a smooth way and easy to adjust the tweak with the captured pivot ball.
The ball raced rear anti-roll bar mount in steel adaptors, which run in nylon spacers in the aluminum 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 track rod guidance.
Front one-way axle
In the front the black anodized aluminum front axle with Japan-made one-way bearings features a free of play and super-true pulley assembly. Spring steel drive cups, strong, long and thin spring-steel driveshaft with CVD system, and ball raced spring steel wheel axles with aluminum quick-change levers. The open front end design allows for very fast and easy removal of the front axle or parts.
The solid rear axle with new lightweight 48T pulley in Serpent spring steel, 9mm wide with 4 slots for the pin.
In the rear strong spring steel drive shafts, spring steel wheel-axles with aluminum quick-change levers and a spring steel 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 aluminum 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 ball raced spring steel wheel axles, with aluminum quick-change levers. The 8.5mm pivotballs are used to adjust camber fast and easy with the smooth hex-shaped plugs. The arms of the floating body mount to the top of the uprights. On top of the up-right spacers can be added under the pivot ball to change roll center and camber change. Optional carbon fiber disks can be mounted on the side of the uprights for aerodynamic reasons.
The adjustable rear upper chamber links mount to the rear carbon camber plate with 2 positions.
The kit features high speed NSK ball bearings, mostly sealed ones with aero shell lubrication or grease. All bearings in the car (except for the servo saver and brake cam) are seated in nylon bushings to reduce vibrations and play.
The shock absorbers are the latest short Serpent Big bore units with membranes. The threaded bodies with setting-nuts (O-ring inside) make ride height changes easy and precise. The front and rear shock are identical. The shocks are very smooth, and easy to assemble and fill. The x-rings are pre-oiled. The shock springs are selected, matched, flat grinded, color-coded units.
The kit does not include motor, batteries, speedo, radio-gear, body, tires-wheels or electronics. The silicone shock oil is included.
The 977-e comes with a full color assembly manual as PDF download, reference guide and exploded views booklet all in one. Set-up sheets (blank and default) are included separately, and 2 decal sheets are included as well.
