Serpent Viper 990E 4wd 1/8 EP ( SER 904006 )

The Serpent Viper 990E is the successor of the successful 988E/989E. We have spent a lot of testing and research to improve the former electric powered 1-8 platforms. We put a lot of emphasis on the flex characteristic since that showed very promising results. On top of that we improved weight, weight distribution and ease of maintenance. A lot of the development went into the transmission. The goal was to have a bullet-proved, yet very free transmission
