Kyosho 40117 EP AIRSTREAK 500 FRP Hull Racing R/C Boat  [KY40117]

Performance Profile of the Kyosho 40117 EP AIRSTREAK 500

The Kyosho 40117 EP AIRSTREAK 500 is a purpose-built R/C craft for pilots chasing speed and precise handling. Its 660mm FRP hull uses a refined bottom shape that balances strength with agility. The deep-V form, combined with a V-edged step and stringer layout, helps the hull plane quickly while staying composed through fast turns.

Hull Geometry and Handling

The central V-edge step is positioned to improve water contact at the centre of gravity, giving sharper turn response without sacrificing stability. The FRP deck and cabin add rigidity to the structure so the boat takes the knocks of regular use while keeping its shape for consistent handling.

Rudder and Impact Protection

The anodized aluminum rudder, finished in blue, offers solid control and includes an integrated water intake to reduce drag by removing the need for an extra pipe. Its lifting action on impact lowers the chance of serious damage when the rudder hits an obstacle.

Powertrain Options and Cooling

Interior space is arranged to accept a standard R/C radio setup plus a range of motor and battery choices. The supplied water-cooling jacket helps keep a 540-class motor running at good temperatures, and the kit includes three nylon prop types so you can experiment with prop pitch and diameter for the best compromise between acceleration and top speed.

For Canadian hobbyists who like to tune setups, the Kyosho 40117 EP AIRSTREAK 500 delivers a robust platform for racing weekends or fast lake runs. Its mix of stability and tunability makes it a strong choice for experienced model boaters.
