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

Graphite radio tray for HPI Bullet 3.0

This graphite radio tray is an aftermarket replacement part produced by GPM for the HPI Bullet 3.0 MT and ST nitro models. It serves as the mounting platform for the radio gear and nearby electronics, with a focus on stable placement and tidy wiring layout. The description below explains compatibility, installation considerations, and its role in setup and tuning.

Compatibility and role: the tray replaces the stock radio platform on Bullet 3.0 MT and ST nitro-engine chassis to provide a stiffer, low-profile mounting surface. A firmer radio tray helps keep servo leads, receiver, and any small electronics secured during aggressive driving or jumps, reducing movement that can affect steering feel and radio reliability.

Installation notes: the tray is designed to accept the same mounting points used by the original HPI radio tray so installation typically uses existing screw holes and hardware. Verify fitment on your chassis before final assembly, route antenna and servo leads to avoid pinching, and check that the tray does not interfere with fuel tank or exhaust routing on nitro setups.

Tuning considerations: swapping to a graphite tray is part of a chassis stiffness strategy; it can slightly alter chassis feedback compared with plastic trays by reducing local flex. When adjusting setup for handling, evaluate radio and servo stability first after installation, then make suspension or weight-distribution changes as needed.
