Step Up to 3D with the Walkera 4B120

For flyers ready to go beyond basic hovering, the Walkera 4B120 2.4G 4CH RC Helicopter is built to be responsive and compact. Its control layout suits pilots refining aerobatic moves and trimming their setup.

CCPM Mixing and Collective Pitch Dynamics

The Walkera 4B120 pairs CCPM mixing with collective pitch to enable controlled aerobatics such as rolls and inverted flight. Twin brushless motors supply the necessary thrust and efficiency to approach 9 to 10 minutes of airtime on a single 3.7V 500mAh LiPo battery, though exact time depends on pilot input.

Secure 2.4G Pairing and Gyro-Assisted Stability

Using 2.4G radio technology, the Walkera 4B120 makes frequency identification and code pairing reliable so several units can fly in the same location without conflict. The integrated gyro improves handling and reduces pilot correction during aggressive maneuvers.

Walkera 4B120 gives intermediate hobbyists a nimble, reliable platform for learning controlled 3D flight. Its balance of tech and simplicity helps pilots focus on improving maneuvers.

Inspect main and tail blades for nicks, check linkages and tighten any loose screws. Verify the battery connector and ensure the gyro shows normal behaviour before the next flight.
Because of its light weight and rotor size, fly in light to moderate breeze only. Strong gusts will make tight 3D work difficult and may stress components.
Gyro adjustments depend on the onboard system and transmitter settings. Start with factory defaults and make small changes to dial in stick response for your flying style.
Charge the 3.7V 500mAh LiPo with a proper LiPo charger, store at safe voltage between sessions and avoid fully depleting the cell to preserve cycle life.
Replacement main and tail blades match the model's rotor dimensions; use parts specified for this Walkera model to retain correct handling and balance.
