Design
Serpent designer Billy Easton from USA, is part of a team of designers, each with their own specialty. Billy used the input from many Serpent drivers, Team drivers and distributors, to create this EVO version 1/8 buggy. The focus is as always on performance, but we have paid a lot of attention to ease of use and durability.
For drivers that also run electric 1/8 buggy, Serpent offers the Cobra SRX8-E which is based on the same platform and shares many parts with the GP version, so its an ideal combination.
Heritage
Serpent as company started in 1980, and has over 35 years experience in developing, testing, designing and manufacturing radio controlled model cars and is one of the longest existing rc brands in the World with 10 World Championship titles and countless European, American, Asian and national titles won by Serpent drivers !
Serpent Cobra SRX8; Full Details
Chassis
The chassis cnc machined from 3mm aerospace type 7075 T6 aluminium and comes anodised for durability. The shape is wider at the rear to help the chassis roll and drag in rougher conditions. The kick-up angle is optimised to fit with the mating parts. All holes in the chassis are countersunk.The pocket for the flywheel is large enough to suit most commonly used starter wheels. The side guards mount to the bend chassis-sides from the inside with pre-threaded holes in the chassis. The chassis offers good size surfaces for the downstops.
Engine mount
Lightweight CNC machined engine mount in 7075 T6 aluminium with pre-threaded holes and large contact area with chassis, comes grey anodised .
Chassis stiffeners
Extra long chassis stiffeners, front and rear in composite material to offer the right flex and prevents the chassis to bend too much. Easy locking fastening system.
Side-guards
The composite side guards help to keep debris out of the car, add rigidity to the chassis and support the body. The side guards are fixed to the chassis from the top in pre-threaded holes in the chassis. This way the screws are protected well and it’s easier to re-assembly when needed. The side guards feature a pocket on the outside to allow mounting some velcro tape to guide / fix the body.
Steering system – servo saver
The dual axis steering system with integrated servo saver is mounted under an angle for less bump steer and a more direct steering feel. The axis are made in lightweight aluminium. The new bellcrank accepts a bearing raced crossbar with zero slop. It designed with the optimal Ackermann to increase the cars drive-ability.
Servo saver
These servo saver parts not only have the right Ackermann, but also have a good internal servo saver design. It incorporates a helix in order to guarantee the proper operating of the servo saver assembly. The servo saver spring is protected by a dense foam cover, to keep debris out. The spring pre-tension clamp nut can be locked in place to avoid turning loose.
Radio-tray
The easy to use and durable radio tray is made as low as possible but in such way that all electronics fit in easy and well. Its features a separate section in the front for the battery pack, to have the heavier part more front. The lid has 4 screws. Both servo’s fit in nicely with plenty servo-spacers to mount them on the right height. The chassis below the servo’s has lower pockets to allow mounting the servo’s very low. Of course you need to think about chassis flex / torsion, so don’t mount them too low. The transponder, small or medium type, has a nice flush mounted holder included. The receiver box also has 4 small screws for easy and fast access. You can mount a standard switch, or use the supplied cover in case you use another solution. 2 carbon look decals are included to cover the battery and receiver box.
Fueltank
The 125cc fuel tank with the spring and cap allow the pressure to be more equal across the entire top of the cap, as well as the design of the cap has no flex . The clunk has been enlarged so it will sit at the bottom of the tank and will not pop up or float at the bottom. While the drain section on the top has been improved where there is now a 4mm hole that will allow dirt and debris to escape and not clog. The fuel-tube clips now mount to the tank with screws so you wont have to worry about losing them. The tank pull will enable faster and more secure refuelling. The tank is further away from the exhaust , which will prevent melting of the tank. The kit includes purpose made insert to reduce the content if needed. The tank mounts on 2 strong composite poles with rubber grommets for flexible mounting and allow easy disassembly for checks and cleaning.
Airfilter
High quality 2 piece dense foam for perfect filtering ( use top quality air filter oil only ). The holder allows for easy assembly. On the front top side the mount is attached to the center support with a spring wire, fixed with a body clip. The new rubber elbow allows for good airflow and features wide grooves to apply tie-wraps.
Center diff mount
Durable center mounts with large size bearings to mount the brake system and center differential. A moulded brake disk guider is mounted on the brackets. The whole system is made as low as possible for CG reasons. The sleek top-cover keeps dirt out and guides the 2 brake cams.
Brakes
The SRX8 provides a conventional braking system with brake cams, steel disks and steel pads with effective pre-glued brake pads .
Clutch
The effective 4-carbon shoe race clutch is continued . It can be completely pre-assembled and then be mounted to the engine. The system comes with a light and small aluminium flywheel and durable spring steel 14T clutch-housing .
Differential cases
The strong moulded differential cases which contain the differential and supports the shock towers.
The differential front and rear can be removed after taking out only 4 screws and removing the anti-roll bars, super-easy !
Differentials
The compact gear diffs with large oil volume. The diff has cavities designed specifically for closed cell foam. This foam will compensate for expansion of the oil, which will allow us to fill the diffs more full, keeping the gears fully engulfed in oil. The cavity where the gears rest has also been redesigned so that there is not low pressure zones outside of the gears. This will keep more oil on the gears even when spinning at high rpms. This in turn will keep the diff more consistent at low and high speeds as well as hot or cold .
Differential gears 28 / 14 / 44
The hard metal 28T and 14T satellite gears have a larger overall diameter, to make sure they are more in oil, making the diff more consistent , smoother and stronger . The steel 44T ring gear is light and has a perfect match with the new 28T gear.
Wheel axles / hex / boots
The durable Serpent spring steel wheel axles are captured CVD style and have rubber boots to protect the system and bearings against dirt and dust, so it will all last longer. The wheel hex is a durable hard aluminium version which fits all popular wheels very well. The pins in use are 3mm ones to increase durability.
Steering blocks
The steering blocks are made in 7075 T6 aluminium and are anodised in black. These steering blocks have been designed to allow you to change the Ackermann at the steering spindle as well as give us the optimal scrub offset in conjunction with the caster block. The bushings press into the blocks and reduce any unwanted play.
C-hubs
The new 15 deg c-hubs are made in 7075 T6 aluminum and are anodised in black. These open style very durable units allow enough space to allow for the maximum steering-angle and allow space to mount the rubber dust protectors on the CVD system. As optional we offer 13, 17 and 19 dgr alu c-hubs too.
Uprights
The new strong composite uprights come into play on the Team edition. Offering 2 lower and 4 upper positions for set-up.
Wishbones
Very durable and long moulded wishbones front and rear. The composite is chosen to have enough flex when needed. The design has pockets in the top and bottom part of each arm to mount the standard moulded insert plates, or the optional carbon fibre ones. In that way you can choose the right arm flex for each condition. Even different or no inserts front or rear and mixing moulded and carbon inserts is possible. The moulded inserts will stiffen the arms only a little, but keeps them cleaner. The carbon ones, or mixed with moulded ones will stiffen the arms a lot. Many options to try and apply.
Mudguards
The mudguards are offered in lightweight transparent polycarbonate and can be left clear, be painted or skinned as prefered.
Suspension brackets
The suspension brackets are CNC machined in 7075 T6 aluminium and grey anodised. They key into the chassis for perfect fit. The brackets have precision machined pockets to use inserts to alter the set-up.
Anti-roll bars
The anti-roll bar system is the best around. Precision made wire runs in ball raced adaptors on the front and rear diff case-plates. Superfree. The wire connects to a ball joint which is fitted with a pivot ball to the wishbone. The works !
Shock towers
The front and rear shock towers are durable 4.5mm 7075 T6 aluminium units, CNC machined and laser engraved with Serpent logo.
Shocks
Durable polished steel 3.5mm rods are used with hard anodised caps and threaded shock-bodies. The seal pack consist of machined bushings and new x-rings and is kept in place with a small inside clip. The shock pistons are machined delrin units for best performance. The shocks in the kit are membrane style, with emulsion type hard coated caps and seals to be offered as option.
Shock springs
Race shock springs which are pre-selected and paired. The shock springs are grinded flat for perfect operation.
Wing rear black
The new flat type rear wing is a very effective medium downforce unit with large side wings. The decal sheet offers side wing decals to apply.
Wing holder rear
The rear wing holder is a super durable and light one piece molded unit. The set includes wing-spacers to put the wing under a range of angles.
Body
Avenger style high downforce body is developed for the SRX8. Cab-forward style body with small fin on the roof for stability. Nice flowing sides with small rear upward fins for rear downforce. Enough space to allow for air filter, engine head, carburetor and exhaust / exhaust adaptor. Top quality polycarbonate. The body has nice trimlines for easy cutting. Same for the body holes. A masking sheet is included to assist with paintjob preps.
Body mounts
This rear body mount has a rubber cushion in it. It allows the body mount to rotate front to rear in an impact or crash. This saves the body from breaking or tearing. The front one is a fixed type and is easy accessible.
Ballbearings
Top quality shielded NSK bearings with grease throughout the kit.
