Meet the new Serpent Cobra SRX8 1/8 Nitro Buggy! First seen in an on track teaser video, the new SRX8 comes packed with a ton of high performance features including new gear differentials with a larger oil capacity and built in pressure compensating system, a gear mesh plate system which allows engine removal without disrupting the gear mesh, top and bottom suspension arm inserts that give you multiple flex adjustment options, and much more! See the rest of the details and a bunch of pictures after the jump!
The Cobra SRX8 chassis cnc machined from 3mm thick aerospace type 7075 T6 aluminum and comes hard anodized for durability. The new shape is wider at the rear to help the chassis roll and drag in rougher conditions. The kick-up angle is optimized to fit with the mating parts. All holes in the chassis are countersunk. The chassis features 2 large pockets, one is for the steel skid plate and one for the steel gear mesh plate. There are 2 keyholes to center-fix the front and rear suspension brackets in place. 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 down stops.
The Cobra SRX8 cnc machined steel skid plate will protect the chassis at the rear end where it wears most. Its easily replaceable by a new one, with just 4 screws. Optional ones in other materials to follow.
The Cobra SRX8 steering blocks are made in 7075 T6 aluminum and are anodized 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.
A really cool and innovative way to mesh the gears perfectly and easily. The Serpent Cobra SRX8 cnc machined mesh plates come in 3 size included in the kit. It will perfectly mesh the clutch and main gear. The mesh plates have increments of 0,1mm . This new system will make sure you can get the engine out and inside the car faster and be sure the mesh is perfected and the engine straight. In total we offer 5 mesh plates to suit all common ratio’s used, but 3 sizes are included standard for fine-tuning.
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.
The composite side guards help to keep debris out of the car, add rigidity to the chassis and support the body. The Cobra SRX8 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 its 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.
The dual axis steering system with integrated servo saver is mounted under an angle for less bumpsteer and a more direct steering feel. The axis are made in light weight aluminum. The new bellcrank accepts a bearing raced crossbar with zero slop. It designed with the optimal Ackermann to increase the cars driveability.
These new servo saver parts not only have the new Ackermann, but also have a new 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.
The Serpent Cobra SRX8’s 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 decals are included to cover the battery and receiver box.
The Serpent SRX8’s 125cc fuel tank is a a complete new design. 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 loosing them. The tank pull will enable faster and more secure refueling. The SRX8 tank has been re positioned so that its 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 dis-assembly for checks and cleaning.
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.
Driveshafts / transmission
The Serpent Cobra SRX8 spring steel driveshaft are equal in length in front and rear and 1 of the central ones, which is easy for spares stocking.
Center diff mount
Durable center mounts with large size bearings to mount the brake system and center differential. A molded 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.
The SRX8 provides a conventional braking system with brake cams, steel disks and steel pads with effective pre-glued brake pads .
The strong molded 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 !
The SRX8 diff housing has been completely re-designed to make way for evolution in diff technology. The diff now 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 SRX8’s steel 44T ring gear is lighter and has a perfect match with the new 28T gear.
Lightweight CNC machined engine mount in 7075 T6 aluminum with pre-threaded holes and large contact area with chassis, comes grey anodized.
Wing holder rear
The SRX8 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.
The durable Serpent Cobra SRX8 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 aluminum version which fits all popular wheels very well. The pins in use are 3mm ones to increase durability.
The new 15 dgr c-hubs are made in 7075 T6 aluminum and are anodized 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 and 17 degree aluminum c-hubs too.
The uprights are made of 7075 T6 aluminum with black anodizing and are universal ones to be used left and right. The new uprights have the roll center adjustment in them with small inserts. Set screws are used to tighten down on the hinge pin to eliminate any unwanted play. In the bottom part 2 threaded holes are made to allow for mounting the optional brass weights of 15 gr each for rough conditions.
Very durable and long molded wishbones front and rear. The SRX8 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 molded insert plates, or the optional carbon fiber ones. In that way you can choose the right arm flex for each condition. Even different or no inserts front or rear and mixing molded and carbon inserts is possible. The molded inserts will stiffen the arms only a little, but keeps them cleaner.The carbon ones, or mixed with molded ones will stiffen the arms a lot. Many options to try and apply.
The mudguards are offered in lightweight transparent polycarbonate and can be left clear, be painted or skinned as preferred.
The suspension brackets are CNC machined in 7075 T6 aluminum and grey anodized. They key into the chassis for perfect fit. The brackets have precision machined pockets to use inserts to alter the set-up.
The anti-roll bar system is the best around. Precision made wire runs in ball raced adapters on the front and rear diff case-plates. Super free and stabile. The wire connects to a ball joint which is fitted with a pivot ball to the wishbone. The works !
The SRX8’s front and rear shock towers are durable 4.5mm carbon fiber units, CNC machined.
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 aluminum flywheel and durable spring steel 13T clutch-housing.
Race shock springs which are pre-selected and paired. The shock springs are grinded flat for perfect operation.
The shocks are a completely overhauled design. Durable polished steel 3.5mm rods are used with hard anodized caps and threaded shock-bodies. A new 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 hardcoated caps and seals to be offered as option.
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.
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.
A new Serpent Avenger style body is developed for the SRX8 with medium level downforce. 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 adapter. Top quality polycarbonate. The body has nice trim lines for easy cutting. Same for the body holes. A masking sheet is included to assist with paint job preps.
