Spyder SDX4 EVO Overview and Key Improvements
RC drivers looking for a precise, adaptable 1/10 buggy will find the Serpent 500021 Spyder SDX4 EVO a compelling option. This EVO variant refines the platform with practical upgrades aimed at both competitive drivers and dedicated hobbyists.
Chassis Highlights
The SDX4 EVO uses a 7075 T6 aluminum chassis engineered to balance stiffness with controlled flex. Countersunk mounting holes keep the underside smooth for fewer hang-ups, while composite side guards and a centre spline add strength and allow straightforward track-side changes.
Suspension Tuning Options
Front and rear closed-type composite arms are standard, with optional carbon inserts for when extra rigidity is required. Multiple shock leverage positions let you tune roll and responsiveness, and hard-coated aluminum brackets give consistent geometry under load.
Drivetrain Upgrades
Drivetrain reliability is improved with spring steel CVDs and driveshafts throughout. The driveshaft pins are 2.5mm for secure retention, and the revised two-pad slipper clutch lets you fine tune power delivery for dirt, Astroturf, or carpet surfaces.
Flexible Setup Choices
There are several battery and motor layout options, including shorty and saddle pack arrangements, so you can dial in weight distribution. A clear manual and setup sheet are included to help get the car configured quickly for different conditions.
