Serpent X20 Aluminium Honeycomb Chassis Flex for Mid-Motor Setups - Arrowmax AM-950021  [AM-950021]

Aluminium flex plate for Serpent X20 tuning

The Arrowmax AM-950021 is an aluminium honeycomb chassis flex plate intended as a drop-in upgrade for Serpent X20 platforms. It does not alter suspension geometry but changes overall chassis stiffness so builders can tune mid-motor behaviour on 1/10 electric touring cars using the Medius X20 MID series layout.

In use this part helps adjust traction and weight transfer during cornering by providing a more consistent metal flex than plain sheet aluminium. The honeycomb profile keeps mass low while delivering a controlled bend characteristic compared with flat plates. Installation commonly replaces the stock flex element or works with existing mounts without moving core items like the servo, ESC, or motor.

As with any scale upgrade, final fit depends on chassis cutouts and screw boss locations. Check alignment with your mounting pattern and confirm there is no contact with wiring, the electronics bay, or suspension arms before tightening hardware.

Choose this chassis flex when you want a repeatable, metal-based flex signature for mid-motor Serpent X20 builds; verify fit against SER400033 layouts and progressively adjust mounting torque to dial response while avoiding stripped bosses.
