Walkera WK4#6 Metal Upgrade Brushless Indoor Helicopter with WK-2402  [WK4#6]

Indoor precision with the Walkera WK4#6

The Walkera WK4#6 Metal Upgrade Brushless Helicopter is aimed at hobby pilots who focus on indoor flying. This ready-to-fly (RTF) package includes the WK-2402 transmitter and 2.4GHz control to give responsive inputs and steady handling inside tight spaces.

Engineered for steady hover and control

The Walkera WK4#6 uses a straightforward swashplate layout combined with Bell-Hiller mixing for predictable stability in hover and slow flight. Its shaft-driven arrangement reduces drivetrain loss so the small airframe stays balanced and efficient during practice sessions.

Efficient low voltage brushless drivetrain

Built around a mature low voltage drive concept, the WK4#6 follows energy-conscious design principles. The low voltage, high torque brushless motor supplies reliable thrust and longevity for repeat indoor flights.

Mini 4-channel agility for tight spaces

This compact 4-channel model is optimised for indoor use and typically achieves about 9-10 minutes per charge. The small footprint and nimble controls suit pilots working on manoeuvres in confined rooms or halls.

Walkera WK4#6 fits pilots who want a compact, efficient indoor helicopter that balances stability and manoeuvrability for both learning and relaxed flying sessions.
