Lightweight Carbon Upgrade: Serpent 401977 X20M

The Serpent 401977 X20M Carbon Chassis is aimed at racers wanting a nimble, durable base for the Medius X20 Mini EP. Manufactured from high-grade carbon fiber, it balances stiffness with low weight to help maintain consistent handling over varied track conditions. Ideal for replacing an old plate or trimming gram weight in a race setup.

How Carbon Improves Lap Performance

With a superior strength-to-weight ratio, carbon cuts mass where it matters and preserves torsional rigidity. That combination reduces pendulum effects and helps deliver more immediate steering response, which can be felt when exiting corners and launching down straights.

Precision Fitment for Medius X20 Mini EP

Every hole and edge is profiled to match Medius X20 Mini EP chassis geometry for hassle-free fitting. The Serpent 401977 shape simplifies alignment and secures standard mounting hardware for a neat, repeatable setup.

Yes, its balance of weight and stiffness makes it a practical upgrade for club-level competition, helping with consistency through multiple heats.
Installation usually requires basic RC tools like hex drivers and thread locker. No specialised jig is needed if your Medius X20 Mini EP mounts are standard.
Try small roll centre and spring rate adjustments to match the lighter chassis behavior. Fine tuning ride height and camber will help extract balance improvements.
Carbon is tough but can crack on heavy impacts. Inspect the lamination and mounting holes after hard hits and replace if you spot delamination or deep fractures.
