HPI Bullet 3.0 MT and ST Low-Profile Graphite Radio Tray GBMT014MC by GPM  [GBMT014MC]

Low-profile graphite tray for Bullet 3.0

This graphite radio tray is an aftermarket upgrade for HPI Bullet 3.0 MT and ST nitro chassis. It creates a firmer platform for radio gear and nearby electronics while helping maintain a tidy wiring layout. Below we outline compatibility, fitting guidance and how the tray influences setup choices.

Compatibility and role: the tray replaces the factory radio platform on Bullet 3.0 MT and ST nitro chassis to provide a stiffer, low-profile mount. A firmer platform reduces unwanted movement of servos and the receiver during hard driving and jumps, improving perceived steering consistency.

Installation notes: the design follows the original mounting point layout so fitting usually uses the stock screw holes. Check that antenna and servo leads are routed without pinching, confirm screw lengths match thread depth, and ensure the tray does not obstruct the fuel tank or exhaust paths on nitro versions.

Tuning considerations: a graphite tray is one element of increasing chassis stiffness and can subtly change how the car feeds back through the steering. After installation, assess radio and servo stability and then fine tune suspension or weight distribution if handling shifts.
