The Serpent 500021 Spyder SDX4 EVO updates a respected 1/10 chassis with practical revisions focused on tunability and longevity. It appeals to racers and advanced hobbyists who tweak their setup for performance.
The chassis uses 7075 T6 aluminium to deliver a reliable foundation with a tuned flex profile. Countersunk fixings keep the undertray tidy, and composite side guards plus a centre spline reinforce key load paths without adding unnecessary weight.
Closed-type composite arms are fitted front and rear, with optional carbon inserts available to stiffen the layout. Several shock mount positions give a wide tuning range, while hard-coated aluminium brackets maintain accurate geometry under stress.
A full set of spring steel CVDs and driveshafts improves durability. The system uses 2.5mm driveshaft pins for dependable retention, and the upgraded two-pad slipper clutch broadens the adjustment spectrum for diverse track grips.
Multiple battery layouts, including shorty and saddle pack, allow riders to alter balance and handling. The package includes a comprehensive manual and setup sheet to help reproduce effective configurations on different days.
In short, the Serpent Spyder SDX4 EVO offers a durable, tuneable base for competitive builds and hobby projects alike.
