![]() IMPACT RESISTANT POLYCARBONATE HULL Two-piece shoebox construction for extreme hull durability. Molded composite material is much more impact resistant than fiberglass. |
![]() POLYCARBONATE CANOPY Durable polycarbonate provides a watertight seal and thumb screws mean no tape is necessary to retain the canopy on the hull. |
![]() SPEKTRUM MARINE 4685 WATER-COOLED MOTOR Rated at over 5 horsepower with 85%+ efficiency. This powerful 8S-capable brushless waterproof motor provides more than enough torque to hit 55+ MPH. |
![]() SPEKTRUM SMART 160A HV WATER-COOLED ESC Able to handle all the power needed — programmable, water-cooled, waterproof, and Smart telemetry enabled. |
![]() CLEAN MOLDED COMPOSITE INTERIOR Adds rigidity and strength to the hull. Wood-free to avoid rot and decay. Grease cup prevents grease from spreading inside. |
![]() ALUMINUM PROPELLER STRUT AND RUDDER Both feature anodized aluminum. The rudder has a breakaway feature that protects the hull from damage if floating debris is struck. |
![]() SMART ENABLED Never lose sight of battery capacity when using Smart LiPo batteries. The DX3 transmitter communicates with the Smart ESC and receiver to display remaining battery capacity. |
![]() SR6110AT 6-CHANNEL TELEMETRY RECEIVER The waterproof receiver ensures interference-free operation. |
![]() S904 1/6 SCALE WP DIGITAL SERVO High-torque waterproof digital servo provides reliable steering power in wet marine conditions. |
