NovaRossi top quality engine with lots of torque and topspeed and still easy to start.


Chassisplate in 3mm 7075 T6 aluminium. Kick-up angle on front for stabile landings. Countersunk holes. Slots to locate the front and rear suspension mounts precisely. Angled sides to increase stiffness.

Strong composite sideguards keep most of the dirt out and offer good protection for the valuable gear inside. The sideguards also double act as side stiffners and influence the flex of the chassis overall.

Aligned with chassis kikc-up for precise landings and to protect front suspension holde rand anti-roll bar.

Chassis stiffners
Composite stiffner front and rear, to give extra stiffness, but still allow some flex as needed for extra traction.#

Central radio / servo mount
Composite compact composite radiobox which offers good space for the steering and throttle,-brake servo, the receiver and the receiver battery. The whole assembly including linkages can be taken off easily and fast in one go, when cleaning the car, or doing maintenance.

Central low dual brake system
The Cobra features a low positioned dual brake system with lightweight glass-fibre disks with springloaded race-brake pads. Very effective stopping power.

Serpent selected the Novarossi pullstart engine for the Cobra buggy. The outstanding quality level, high performance, combined with easy starting and long lasting runtime, makes this engine the ideal partner to start racing. Novarossi also offers a special backplate in case you change to a bumpstart system later, so you can continue with the same engine even longer !
The engine is mounted securely on machined aluminium engine mounts.

Polished tuned pipe system
The DragonRC polished inline tuned pipe system works really well with the Novarossi engine and produces a sharp and powerfull tune. Fire it up !

The famous Serpent offroad clutch in 3 shoe version has the right setting for smooth performance, but when you hit the throttle hard it will accelerate the Cobra like crazy.

The foam dual action airfilter sits very low in the car, and snugfits tight next to the fueltank. The large opening in the body for refueling will also allow enough air getting to the filter

Shocktower and bodymounts front
4.0mm thick aluminium anodised shocktower with 3 upper positioning holes for the shocks and and 3 holes for roll-center positions. 1 centrally located adjustable bodymount , and 2 forward mounted adjustable bodymounts.

Angled steering system / servo saver
The bell cranks are angled to reduce the angle of difference between the total caster and steering plane. Therefore you will have less bump steer and a truer steering Ackerman through the entire range of suspension
