Serpent is proud to present the new Cobra SRX8 EVO 1/8 nitro RC buggy! Based on the original SRX8, which was announced last year, the EVO comes packed with multiple upgrades including new 7075 T6 aluminum front and rear shock towers, new dual system membrane/emulsion aluminum shock caps, an updated 7075 T6 aluminum chassis with improved engine position, new molded uprights for increased traction, spring steel center driveshafts, improved suspension arms, additional hinge pin inserts for more settings, and a new high downforce Avenger body. See the rest of the details and pictures of the new Serpent Cobra SRX8 EVO after the jump!
The Serpent Cobra SRX8 EVO chassis cnc machined from 3mm aerospace type 7075 T6 aluminum and comes anodized for durability. 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 down stops.
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 its easier to re-assembly when needed. The side guards feature a pocket on the outside to allow mounting some felcron tape to guide / fix the body.
Lightweight CNC machined engine mount in 7075 T6 aluminum with pre-threaded holes and large contact area with chassis, comes grey anodized on the Serpent Cobra SRX8 EVO.
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 Cobra SRX8 EVO 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 light weight aluminum. The new bell crank accepts a bearing raced crossbar with zero slop. It designed with the optimal Ackermann to increase the cars drive-ability.
These SRX8 EVO 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.
The Cobra SRX8 EVO buggy’s 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 Cobra SRX8 EVO 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 dis-assembly for checks and cleaning.
High quality 2 piece dense foam for perfect filtering. 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 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 Serpent Cobra SRX8 EVO provides a conventional braking system with brake cams, steel disks and steel pads with effective pre-glued brake pads.
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 14T clutch-housing.
The strong molded Cobra SRX8 EVO 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 compact SRX8 EVO 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 Serpent Cobra SRX8 EVO 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 aluminum version which fits all popular wheels very well. The pins in use are 3mm ones to increase durability.
The 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.
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, 17 and 19 dgr alu c-hubs too.
The new strong composite uprights come into play on the Team edition. Offering 2 lower and 4 upper positions for set-up.
Very durable and long molded 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 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 front and rear shock towers are durable 4.5mm 7075 T6 aluminum units, CNC machined and laser engraved with Serpent logo.
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 stable. The wire connects to a ball joint which is fitted with a pivot ball to the wishbone. The works!
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 Serpent Cobra SRX8 EVO features durable polished steel 3.5mm rods are used with hard anodized 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.
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 sidewing decals to apply.
Avenger style high downforce body is developed for the Serpent Cobra SRX8 EVO nitro buggy. 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 trim lines for easy cutting. Same for the bodyholes. A masking sheet is included to assist with paint job preps.
