XRAY 301061 T4'20 1.6mm Graphite Upper Deck Precision Tune  [XR-301061]

Setup and tuning for the XRAY T4'20 1.6mm upper deck

The XRAY 301061 T4'20 Graphite Upper Deck is a precision component built to sharpen handling across changeable grip levels. This 1.6mm graphite plate helps racers dial in chassis response when running on aluminium underbodies in lower to medium traction situations.

Adjusting flex modes

The upper deck is designed for balanced flex without introducing uneven behaviour. It sits symmetrically to deliver predictable response. Use these connections to alter chassis feel:

• Soft Setting: Leave the top deck free from the stand to maximise lateral compliance and deliver sharper initial steering, though it will demand smoother throttle and steering inputs.
• Medium Setting: Fit a ball-bearing link to the stand so the deck can move side to side while remaining more rigid front to rear, giving a controllable compromise between agility and stability.
• Stiff Setting: Install a fixed bushing to lock the deck to the stand for minimal flex, improving straight-line stability and predictability.

Recommended track surfaces

This upper deck works particularly well with an aluminium chassis on surfaces where traction is low to medium. The graphite keeps weight down while giving a firm mounting platform for tuning handling balance.
