    • Front CVD and rear dog bones in Serpent Spring Steel
    • Low and wide front bumper


    Symmetrical chassis plate for even flex and torsion in 3mm carbon fiber, lowered where the motor mounts as low as possible in the car.

    Top deck

    The 2mm carbon fiber top deck connect the front and rear suspension.

    Battery holders

    The battery holders are in carbon fiber and have sleeves to enable use of battery mounting tape easily.


    very low mounted servo, a strong carbon/alu holder which is centrally mounted for even flex

    Motor / midshaft / anti-roll bar holder

    the motor is mounted on a low strong aluminum holder, which doubles as mid-shaft holder and rear anti-roll bar holder as well.

    The mid-shaft mounts in 2 separate holders with the ball bearing inside to enable a fast and easy change of gears.

    RCM shocks

    Hard Teflon coated threaded shock bodies in high quality aluminum. Super smooth O-ring / bushing package, to guide and seal the spring-steel piston rods. Precision molded pistons included in 3 types. Threaded pre-load shock nuts in alu with O-ring inside. Light but strong nylon spring-cups. Tight fitting ball-joints in top and bottom.

    Front bumper

    Newly designed lower front bumper with aerodynamic effects and better protection. Some parts of the lower bumper can be cut open to create more steering. The upper bumper / body mount holder connect to the lower one to create a strong structure to absorb the crashes. The foam elements ( normal or large) can still be placed but are optional.

    Shock tower front

    3.0mm carbon fiber shock towers with 3 positions for upper shock mounting. In the center you can mount the 3rd body post as needed.

    Front brackets

    A compact and superlight structure of top-quality aluminum parts consist of top-brackets, L and R equal bearing brackets, lower suspension bracket front, L and R equal FR-RR standing suspension holders and rear, anti-roll bar holder and Lightened machined alu brackets, equal left and right, toothed section allow setting belt tension with extenders which seat the bearings. Machined alu top brackets L and R version to hold the upper arms. Suspension bracket front . All crafty machined and grey anodized parts. 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 aluminum pivot balls, which pivot in light nylon cups. Medium hard nylon used for the arms to have some flex to increase grip, and make them most durable. The arms pivot on the inside on spring steel pins. The pivot-inserts are used to change roll center. Small grub screws mount in the upper bracket to control down stop. Easy to access and change ride height, front width, toe-in, caster and camber.

    Steering blocks / wheel axles / cvd

    Very strong nylon steering blocks with 2 Ackermann positions . The spring-steel wheel axles are seated in high speed bearings. The light and durable spring-steel cvdí s bring all the power to the front wheels. Wheels are mounted to orange anodized high grade aluminum hex-adaptors using serrated wheel nuts.

    Anti-roll bar front

    The balanced wire type anti-roll bar 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 pivot ball/cup system, which provides direct and smooth operation and is easy to set.

    Servo-saver / steering

    The centrally mounted steel servo-saver post fits the spring-loaded balanced 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 bump steer.

    Rear brackets

    Very open rear end design with a composition of 8 machined alu brackets, allowing for controlled flex and easy maintenance. The differential brackets, L and R equal, are toothed and seat the bearing holder, which allow for setting belt tension. Itís 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 V1 version, which is narrow than used on the 733, to achieve the new geometry together with the near lower arms and uprights.

    Rear carbon shock tower and camber bracket

    The 3.0mm carbon shock tower has 3 upper mounting position for the shocks and it mounts the body-poles. The camber bracket offers 8 positions to choose from, 4 inner and 4 out holes.

    Suspension rear

    The new lower rear arms together with the new uprights create the new geometry in the rear, to 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 composite lower wishbones feature a mounting position for the anti-roll bar linkage bracket in carbon, which moves the link position more outside and higher. Itís 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 itís not needed. By placing the lower shock further out, you will get even more steering .

    Uprights / wheel-axles

    Durable medium type nylon uprights, which seat the wheel-axles bearings. The upright offers the mounting position for the steel camber-rod with L/R threading. The durable spring steel wheel axles bring to power from the gear-diff to the wheels. Wheels are fitted on high grade anodized alu wheel hex adaptors and secured with serrated flanged.

    Anti-roll bar rear

    The balanced wire type anti-roll bar 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 steel rod. The lower arms offers 2 mounting positions to choose from.


    Compact, durable and light gear differential. Precision molded steel gears, 2 small and 2 large ones. Steel internal shaft. The very durable and light spring steel lightened diff-adaptors connect to the driveshafts. The gear diff is same front and rear.

    CVD driveshafts

    Spring steel, light and very durable CVDís used in the front. Precision mounted hard steel pins


    Spring steel, light and very durable dog bones used in the rear. Precision mounted hard steel pins


    Precision molded super-true pullies, which feature holed sidewalls to let debris move out easier. Light and durable.


    Kevlar reinforced belts with fine pitch. Long-lasting and smooth.


    2 Ball raced belt-tensioners, machined from aluminum mount between the chassis and top deck .


    The 747-e comes with a full color online assembly manual, with easy to follow assembly steps. The manual also includes an exploded views section showing all part numbers, and a full parts-list, showing also all optional for the 747-e.


    The 747 includes one sheet with Serpent generic logoís and one with 747 logoís. Decals are very fine and thin material and come pre-cut.


    The 747-e comes in a strong, small carton box with nice graphics. The packing of the bags follows the steps in the manual.

    Compared to a regular 1/10 scale touring car, the handling is very different, much easier. As you will race with a wider car of 200mm and use foam tires on wider rims. The 1/10 200mm cars are also overall stronger ( and a bit heavier) and can take the extra power you have with ease, without wearing out fast. Even when crashing the 200mm cars are more durable and can absorb more power.

    We recommend to use decent level 3S lipo, 1/10 brushless motor less than 5000kV, combined with a strong 1/8 scale speedo.

    You can also use a brushless set from 1/10 TC touring, but it may not handle the traction created by the foam tires, and cause thermal issue for both speedo and motor. We advise not to use it, or only at small tracks. At larger tracks for sure use the stronger 1/8 speedo.

    The set-up of the 747-e chassis remains very close to the gas-powered one, speed is amazingly fast, and silent. A manual and the set-up sheet are posted online in

    That is one good looking machine. Rear dogbones?
