 Serpent 748-TQ; details

 Chassis
 Symmetrical chassisplate for even flex and torsion, in 7075 T6 aluminium, anodised 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.

 Radioplate
 The 2mm carbon fibre radioplate has multiple functions. It holds the fueltank in place which is mounted on 3 alu posts in rubber. On the right hand side the receiver mounts to a nicely shaped carbon fibre plate that connects to the radiotray, sqeezed in right between belt and tank. The radioplate sits again lower on the car , for lower center of gravity.

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

 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 efficent and easy way. The holder mounts to the radio-tray.

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

 748 receiver box
 The 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 radioplate with a nylon bracket . The box has been moved as much to the inside as possible. On the radioplate a small holder is fitted to accept the plugs of the battery, to act as on/off “switch”.

Battery-holder
 Carbon fibre 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.

 748 fueltank
 Lower and longer durable 75ccm nylon fueltank with transparent material to easy see fuel-content. Large springloaded quick-fill cap with seal with large tank opening for fast and easy refills. The bronze sintered filter will keep fuel clean and make sure tank will empty till last drop if needed. Fueltank sits very low in the car for low center of gravity. Fueltank is mounted with clips on 3 alu posts with rubber buffers.

 Front brackets
 A compact and superlight structure of topquality aluminium parts consist of top-brackets, L and R equal bearing brackets, lower suspension bracket front. The open style design allows for very fast parts exchange as needed, like belt, diff or anti-roll bar.

 Suspension front
 Strong long double A-arm suspension with aluminium pivotballs, which pivot in light nylon cups. Hard type composite arms. The arms pivot on the inside on springsteel pins. The pivot-inserts are used to change rollcenter. Small grubscrews mount in the upper bracket to control downstop. Easy to access and change ride height, front width, toe-in, caster and camber.

 Steeringblocks
 Very strong composite steeringblocks with 2 ackermann positions, L and R use the same . The steeringblocks feature inserts, which allow to change the kingpin inclination to a leading or trailing position. The steeringblocks also allow use of the optional carbon fibre aero disks to be mounted for less flex and a more direct steering feel.

 Wheelaxles / cvd
 The spring-steel wheelaxles 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 anodised high grade aluminium hex-adaptors using flanged wheelnuts.

 Anti-roll bar front
 The ballraced 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 new lowered centraly mounted steel servo-saver post fits the spring-loaded ballraced 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 aluminium 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 belttension. Its very quick and easy to mount a differential and or replace a belt. The machined aluminium lower suspension brackets have roll-center inserts with 3 positions to choose from. The rear bracket is the narrow V1 version.

 The 2-speed gearbox shaft holders, double up as anti-roll mounts, and brake system basis. All topquality machined parts with anodising and laser-engraving.

 Brake -system
 the low mounted brake system with superlight 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 shocktower and camber bracket
 The low 3.0mm carbon shocktower 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 shocktower 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 aluminium pivotball system allows for fast changes in width and toe-in. On the lower inside the wishbone pivots on springsteel pins, which seat with roll-center inserts in the anodised 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 shockmount 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. Rolll center chnages can be made on top of the upright with shims. The upright can be mounted with the optional carbon fibre aero disks for more rear grip and straight line stability.

 Wheelaxles and driveshaft
 The durable spring steel wheelaxles combined with spring steel driveshafts bring the power from the gear-diff to the wheels. Wheels are fitted on high grade anodised alu wheelhex adaptors and secured with flanged wheelnuts.

 Anti-roll bar rear
 The ballraced wire type anti-rollbar in the rear is really easy to access from the top and change for other type or thickness as needed. The anti-roll bar is linked to the lower a-arms with a spring-steel rod.

 Ball raced belt-tensioner, machined from aluminium and can mount on top or below the radioplate.

 Gear-box SL6 – Xli
 The well proven SL6 gearbox has been redesigned and lighter. Smaller bell, adaptor and shoes reduce overall weigth and rotating mass, so lower intertia. Durable and longlasting gears. High quality bearings. Very grippy smaller springloaded 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 anodised aluminium flywheel has 4 holes to have easy access to keep the flywheel in position when setting the pre-tension. The flyweights are made of topquality 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.
