This antenna grommet keeps water out while allowing any antenna to extend outside of the radio box.
Mounted high for consistent fuel flow, the fuel tank also offers a low center of gravity and a narrow design that fits perfectly in the low-profile cowl.
These rubber bellows keep water out of the radio box while allowing the steering pushrods to move smoothly. Grommets prevent water from entering through the throttle linkage hole or the on-off switch remote hole.
The smart layout of the water-tight radio box provides easy access to your on-board gear.
The switch is remotely operated for convenience by a control rod located on the transom of the boat.
Pure performance.

Knowledge gained from three successful seasons of race-testing inspired the Top Speed 3 Nitro ARR. Its superior handling and impressive speed have already earned World and National Championship titles. A specially engineered fiberglass hull and sponsons help it win competitions. A complete package of GrimRacer hardware keeps the Top Speed 3 going strong all the way to victory.
What updates distinguish the Top Speed 3 from its predecessor?
The center section has a completely new airfoil design, thinner than the Top Speed 2 and with a flat taper on the top of the center section.
The tunnel floor is flat, not curved.
Total width is a half inch (13 mm) less than the Top Speed 2.
Sponsons run flat to the surface and begin to rise up off the surface 12 inches (305 mm) from the transom (compared to the Top Speed 2’s 11 inches).
The 2 inch (50 mm) wide pad that runs the length of the tunnel floor is tapered 0.1 inches (3 mm) thicker at the back, adding lift at the back of the boat when it’s running full-speed.
Sponson angles have been changed for better cornering.
The outside sponson edge is stepped up 3/16" (4.8 mm) and out 1/4" (6.4 mm) to sheer the water exiting the sponson surface.
The cowling is an inch (25 mm) taller at the transom, to better match the cowl height with engine height.
The sharp edges at the transom and leading edge of the center section have a radius to prevent vibration cracks.
The radio box/fuel tank area is now open.
The transom engine mounting surface is a half-inch (13 mm) wide. This allows a drilled and tapped plate to hold the engine to the transom, and replaces the brass inserts used in the Top Speed 2...a better system for securing the engine to the transom.
The tops of the sponsons have been sloped downwards at the back, creating a thinner side profile.
The fuel tank has been elevated, improving fuel draw.
Recovery pads on the bottom of hull are now part of the fiberglass mold.
