Serpent Natrix 750 EVO 4wd 1/10 GP (SER804012)

The chassis is made from 3mm 7075-T6 aluminium and has been improved regarding the flex characteristics

It features a new weight bridge, vibration isolated as already used in the big brother, the 989.

For the front we can also use a small adjustable weight, especially useful under high-grip circumstances

In the rear we now have 2 options for the pivot-width. The default position is the same as in the 750, while the wider option is similar to the 748

The new rear suspension is completely new. It features the possibility of a toe change during suspension travel.
Due to the unique design, there is zero binding as well under all circumstances

In the neutral position the toe-change is absolute zero. In this position the rear end acts like the regular 750 rear end.

The higher the link on the upright, the more toe-gain is achieved under compression, resulting in more rear traction under acceleration

The new front arms are open style for aerodynamic reasons. They feature mounting points for an optional heave damper

The 2-speed gearbox is completely new. It is based on the 989 gearbox and bullet-proofed

A much longer ramp for the roller avoiding locking of the second gear even with excessive wear on the shoes

M4 setscrews for gap adjustment to help keeping the gap constant

2 bearings in the second gear “bell” for better truth of rotation and balance

2nd gear adapter is locked in position to avoid binding and deliver constant performance of engine and gearbox

Newly designed flex cover provides a force free stiffener rod

New shocks and shock towers. These shocks are taken from the 989 and provide trouble-free, low friction action for increased traction

The piston is fixed onto the shaft with a nut. No clipses or shims.

On top of that we payed a lot of attention to the bottom seal. 2 X-rings and a long bushing provide that extra bit of low-friction sealing that keeps the oil inside and the dirt outside

Hard anodized bushings provide a 100% secure positioning of the front upper suspension brackets

As an option the 989 offers a heave-damper setup in the front as well as the rear.

In this way it is possible to change heave adjustments more or less independent of roll adjustments.
As an example it is possible to have a very light roll damping combined with a very high heave damping, something which is not possible with a classic suspension.
The third damper can be used to only alter the damping characteristics without a third spring, but also to add a spring to alter spring rates for heave
The front and rear heave sets are available as an option.

Another option is a side-guard/stiffener for the bodyshell
