Serpent Natrix 748 WC Touring Car

Serpent Natrix 748 WC Touring CarTo celebrate the 2016-2017 IFMAR World Championship win by Dominic Greiner, Serpent introduces the WC version of the very popular Natrix 748 series. Serpent developed new V2 gear diffs for the Natrix, being a slightly different front and rear one, with new case, gears and sealing system, which make it really easy to assemble and maintain. The 748 WC has the new lower big bore shocks included, as well as new larger pullies and a new side belt. Another feature is the light 2-speed gearbox the XLi with small adapter, bell and shoes. Check out the pictures and the rest of the details of the Serpent Natrix 748 WC after the jump!

Symmetrical Serpent Natrix 748 WC chassis plate for even flex and torsion, in 7075 T6 aluminum, anodized and laser engraved. Chamfered edges for more ground clearance when cornering and countersunk holes. Central slots to mount weight, which can slide into the right position and then secured.

Radio plate
The Serpent Natrix 748 WC 2mm carbon fibre radio plate has multiple functions. It holds the fuel tank in place which is mounted on 3 alu posts in rubber. On the right hand side the receiver mounts to a nicely shaped carbon fiber plate that connects to the radio tray, squeezed in right between belt and tank. The radio plate sits again lower on the car , for lower center of gravity.

Central Flex system
The Serpent Natrix 748 WC rear section of the radio plate incorporates a nice flex-control system. It consists of 2 machined aluminum parts. The lower one connects to the radio plate supports an the upper one with screws to the upper alu plate and radio plate. You can either run the 748 rigid with flex . The optional ball-bearings and screws are sold separate. Testing has shown that flex in the center rear of the car has the most effect and reacts most predictable as well.

748 servo holder
A new composite servo holder is designed to have both servo closer to the center line of the car and as low as possible. The 2 lay-down servo’s are seated very close together and mount in a very efficient and easy way. The holder mounts to the radio-tray.

The Natrix 748 WC throttle / brake linkage is same style as used on the 977 1/8 car. A pivot-lever system with an ingenious ball-cup system to the guide the wire and have almost friction free action.

748 receiver box
The Serpent Natrix 748 WC new composite receiver box is small but holds and protects the most common modern receivers easily. The antenna mounts to the top. The box is securely fastened to the radio plate with a nylon bracket . The box has been moved as much to the inside as possible. On the radio plate a small holder is fitted to accept the plugs of the battery, to act as on/off “switch”.

Carbon fiber battery-holder positioned between the tank and pipe, for the best weight balance. The battery is easy to strap down with tape to the bracket. Spacers can be used to mount the battery higher or lower depending on the battery you plan to use.

The pivot-inserts are used to change roll center. Small grub screws mount in the upper bracket to control downstop. Easy to access and change ride height, front width, toe-in, caster and camber.

Steering blocks
Very strong composite steering blocks with 2 Ackermann positions, L and R use the same . The Serpent Natrix 748 WC steering blocks feature inserts, which allow to change the kingpin inclination to a leading or trailing position. The steering blocks also allow use of the optional carbon fiber aero disks to be mounted for less flex and a more direct steering feel.

Wheel axles / cvd
The spring-steel wheel axles are seated in high speed bearings. The light and durable spring-steel cvd’s bring all the power to the front wheels. Wheels are mounted to orange anodized high grade aluminum hex-adaptors using flanged wheel nuts.

Anti-roll bar front
The Serpent Natrix 748 WC ball raced wire type anti-rollbar in the front is really easy to access and change for other type or thickness as needed. The anti-roll bar is linked to the lower a-arms with a unique pivotball/cup system, which provides direct and smooth operation and is easy to set and adjust.

Servo-saver / steering
The Natrix 748 WC new lowered centrally mounted steel servo-saver post fits the spring-loaded ball raced servo-saver system and steering. The inserts allow 2 ackermann settings. Due to the open design the linkages with L/R threading can be reached easily. The whole system allows for very precise steering and minimum bumpsteer.

Middle shaft holder
Machined 2 piece aluminum middle shaft holder, which securely holds the spring steel middle shaft, and doubles up as holder of the pipe-mount.

Rear brackets
Very rigid but open rear end design with a composition of machined alu brackets, allowing for easy maintenance. The differential brackets, L and R equal, are toothed and seat the excentric bearing holder, which allow for setting belt tension. Its very quick and easy to mount a differential and or replace a belt. The machined aluminum lower suspension brackets have roll-center inserts with 3 positions to choose from. The rear bracket is the narrow V1 version.

Brake -system
the low mounted brake system with super light disk allows for smooth and even braking, and the open system avoids overheating. The ball-raced excenter and lever gives a very smooth and direct brake-feeling.

Rear carbon shock tower and camber bracket
The low 3.0mm carbon shock tower has 3 upper mounting position for the shocks and it mounts the body-posts. The camber bracket offers 8 positions to choose from, 4 inner and 4 out holes. The shock tower is prepared to mount the extra body-protectors, which are optional.

Suspension rear
The Hard lower rear composite arms together with the updated uprights create a wider set-up sweet-spot with more grip and more steering. The upper camber rods connect to the carbon camber bracket with 8 mounting positions for roll-center and the camber rod is easy to access and has L/R threading for fast changes. The aluminum pivot ball system allows for fast changes in width and toe-in. On the lower inside the wishbone pivots on spring steel pins, which seat with roll-center inserts in the anodized alu suspension brackets.

Lower rear wishbones
The hard composite lower wishbones feature a mounting position for the anti-roll bar linkage which moves the link position more outside. Its also offers a mounting position for an optional carbon shock-mount bracket, to move the lower shock mount position further out, but for the default set-up its not needed. By placing the lower shock further out, you will get even more steering.

Uprights / wheel-axles
Durable medium type composite uprights, which seat the wheel-axles bearings. The upright offers the mounting position for the steel camber-rod with L/R threading. Roll center changes can be made on top of the upright with shims. The upright can be mounted with the optional carbon fiber aero disks for more rear grip and straight line stability.

Ball raced belt-tensioner, machined from aluminum and can mount on top or below the radio plate.

Gear-box SL6 – Xli
The well proven SL6 gearbox has been redesigned and lighter. Smaller bell, adapter and shoes reduce overall weight and rotating mass, so lower inertia. Durable and long lasting gears. High quality bearings. Very grippy smaller spring loaded 2-speed shoes, easy to set.

True Motion Centax clutch
Serpent invented the Centax clutch in the mid 90-ties, and all brands followed it. Small improvements are found to make the original system even better. The True Motion Centax has a flat flywheel, and the taper part on the pressure plate. This allows the flyweights to work even better. The hard anodized aluminum flywheel has 4 holes to have easy access to keep the flywheel in position when setting the pre-tension. The flyweights are made of top quality teflon and feature an additional hole to use grubscrews to make them heavier. The red friction clutch shoe is very grippy, and works excellent with the steel clutch housing. The hard anodised gears screw onto the threaded steel bell.

Engine mount
