GSR21.9R

The Serpent Viper 990E Evo is the successor of the successful 990E 

We have spent a lot of testing and research to improve the 990E. As in   the 990 Evo Nitro car, we updated the front and rear arms and added the flex   shock mounts which are working so well in the Nitro car.  

Off course we kept the outstanding features of the 990E, like the low weight,   excellent weight distribution and ease of maintenance. 

A further big feature is the bullet-proved, yet very free transmission
