The new Serpent 720 continues to improve upon the long line of championship-winning, ultra-successful, and highly-competitive 1/10th scale cars from Serpent, setting new standards in quality, ease of assembly, ease of use, and outright performance.
The Serpent 720 features the following major enhancements:
- Wider sweet spot makes for easier setup
- Easier assembly
- Front & rear factory assembled gear differentials
- Optimised geometry
- Pre-assembled RCC shock absorbers
- Improved features throughout
Serpent 720 Features
New Rear end: The new rear end of the Serpent 720 features new 1-piece lower wishbones and fully adjustable uprights. As with all the wishbones on the car, the lower wishbones can be used on both the left and right sides, minimizing the number of spare parts needed to bring to the track. The rear upright features robust pivotball mounting points on the bottom and two upper camber link mounting holes for fine-tuning rear roll center.
Rear anti-roll bar The all new rear anti-roll bar for the Serpent 720 is now ball-raced for extra precision. Stiffness is quickly and easily adjustable by changing the linkage mounting points on the lower wishbones or alternatively by changing the position of the ball joint pivot point on the roll bar itself.
To further stiffen the rear end of the car, we have created a distinctive S-shaped carbon brace which spans the two rear bearing blocks.
Linkage replaces rear upper wishbone: For the Serpent 720, Serpent has for the first time used an adjustable linkage instead of a rear upper wishbone. This linkage is solid and lightweight â€” easily handling impacts â€” while offering improved and simple adjustment. The two inner mounting positions of each camber link offer an easy way to adjust camber rise.
New Braking system: The Serpent 720â€™s new braking system is similar to that pioneered on the Serpent 960 in that it does away with the need for guidance pins in the chassis plate. The 720 comes with a single ventilated brake disk to further improve braking performance and consistency.
Fuel Tank: Serpent has included its race-proven 75cc fuel tank in the 720. The tank is top-mounted using rubber-covered aluminum mountings to isolate the tank from vibrations, and small body clips allow for quick & easy removal.
The new tank also has another of Serpentâ€™s innovations: the anti-fuel-lock (AFL) fuel tank lid. The AFL lid contains an air chamber to prevent fuel from blocking the back-pressure line during high-speed cornering.
Rear body mount: By simplifying the rear end of the Serpent 720, it is now possible to remove the rear axles with only 6 screws. This configuration also makes it very easy to adjust the rear lower roll center positions. Another unique feature of the rear end is that the body mounting posts are no longer mounted directly to the carbon shock tower but are instead mounted to a flexible composite body mount plate. This reduces the chance of shock tower breakage even in large accidents.
All new geometry: The Serpent 720 features all-new geometry throughout, which allows for a wider â€œsweet spotâ€ making the car easier to set up. As expected from Serpent, the drive train is comprised of high-quality, hard-wearing components.
Gear Differentials: Newly-designed front and rear gear differentials give smooth differential action and high durability, and gear slippage is non-existent due to the geared design. Performance and tuning characteristics are easily adjusted via gear oils of different thicknesses.
RCC Shock Absorbers: The RCC shock absorbers are the smoothest and easiest to build shocks ever designed. Machined from metal and unique in that the shock bodies only open on the bottom half, they are really simple to assemble. They come with a fixed piston and no longer use a diaphragm as with the previous shocks. The result is an ultra-smooth and air-free shock absorber thanks to the self-bleeding system incorporated into the design.
Another great benefit is that these shock absorbers come pre-assembled in the kit, so you need only add shock oil.
Nose block: The new nose block ensures that the downstop settings are not altered by impacts. This piece also doubles as a neat personal transponder mount.
Lightweight transmission: The Serpent 720 comes with the same lightweight and well-tested transmission that was in the Serpent 710. The gearbox and clutch features a fine gear pitch and lightweight components, which result in better acceleration whilst the race-winning Centax-III clutch system is easily adjusted and performs brilliantly.
Chassis Plate: To ensure rigidity throughout the car we have supplied the Serpent 720 with a 4mm chassis plate as standard. Made from high-grade aluminum, this chassis plate features countersunk screw holes along the bottom to ensure that no screws come in contact with the ground. The chassis also features chamfered edges to give greater clearance when going over curbs or when running low to the ground.
To keep the center-of-gravity as low and as centralised as possible, the chassis also houses the car’s battery pack.
Chassis Stiffeners: Rigidity is important in a modern day chassis, and this car is no exception. Sporting graphite side plates, a technology that Serpent pioneered, this car is ultra stiff and allows the shock absorbers and suspension components to work more effectively by reducing unwanted chassis flex.
The left chassis stiffener also doubles as the mounting point for the side belt tensioner.
Front Anti-roll Bar: The front anti-roll bar uses the effective blade system. The mounting levers are used to adjust both upstop and downstop settings.
Brake Disk: Precision machined disk brake, due to its excellent cooling characteristics, this brake disk allows smooth and precise braking. Itâ€™s also very lightweight and is also very cool looking. Simple and effective stopping power.
Wheel Axles: The wheel axles are made from the highest quality steel. Sporting a threaded shaft to mount the wheel, these parts are built to last. The Serpent 720 uses the same wheel axles on all 4 corners of the car.
Bearings: Supplied with new improved orange-sealed high-quality lightweight bearings throughout, the drive train is very efficient and runs very smoothly.
Driveshafts: Made to the usual high standards, the 720’s driveshafts are long-lasting, ultra-strong pieces put the power to the ground. The 720 uses the same driveshafts on all 4 corners of the car.
Drive Belt System: To further improve performance and lower drivetrain friction in the drive train, the Serpent 720 sports a completely new drive ratio that makes it suitable for all tracks. The car comes with 3 completely new, narrow, low friction Kevlar belts.
Aluminum Pivot Balls: The ultra-lightweight but very strong aluminum pivot balls provide a huge weight saving over the steel versions without comprimising strength, and we have provided them as standard.
Front bumper & Body mount: The Serpent 720 features a new front bumper and bumper mount. The bumper plate is made from a high-quality composite that is impact resistant. This is all protected by the low profile foam bumper which can withstand huge impacts and still protect your car. The front bumper mount is also the mounting point for the front body posts.
Exhaust mounting spring: The exhaust mount is a spring-type mounting wire that isolates vibrations. The wire mount is attached to the radio plate by a mounting post and secured in place with a set screw.
Wheels: These beautiful wheels have proved themselves to be great in the corners and everywhere else on the track due to their non-deforming construction. Fluorescent yellow in colour, they are supplied with the Serpent 720 kit, minus the tyres.
Adjustment: The Serpent 720 has been designed with the highest level of competition in mind and is therefore fully adjustable. The racer can change numerous settings easily and effectively, including the suspension geometry. Upstops and downstops can be easily accessed and easily adjusted for optimum handling, as can the carâ€™s roll centers at both the front and rear of the car. Castor, toe, and camber are also easily adjusted.
