Take on 3D Flight with Walkera 4B120

For pilots advancing from trainer-class birds, the Walkera 4B120 2.4G 4CH RC Helicopter delivers a compact, manoeuvrable package. Its design helps focused practice on collective pitch techniques and transitional aerobatics.

CCPM Steering and Collective Pitch Handling

The Walkera 4B120 uses CCPM mixing combined with collective pitch control to enable controlled rolls, inverted flight and aggressive swoops. Twin brushless motors give efficient thrust and typically yield about 9 to 10 minutes of flying on a single 3.7V 500mAh LiPo cell, subject to throttle use.

2.4G Band and Gyro Stability

Equipped with modern 2.4G radio tech, the Walkera 4B120 supports clear code pairing so multiple machines can operate together without interference. The integrated gyro offers flight smoothing for steadier inputs and safer practice sessions.

Walkera 4B120 is a capable choice for pilots wanting a small, responsive collective pitch heli for practicing 3D basics. Its setup promotes safe progression with predictable handling.

The Walkera 4B120 handles well in open parkland but needs room for safe 3D moves because of the 302mm main rotor span. Choose a clear area with minimal wind for best results.
Progress varies, but with regular short practice flights many pilots can achieve tidy rolls and simple invert transitions within a few sessions. Reduce rates while learning to limit surprises.
This model pairs with the WK-2601 transmitter and RX-2605A receiver as part of its control system, providing standard 2.4G connectivity and binding procedures.
Yes, common spare part designations include the tail motor WK-WS-10-002 and main motor WK-WS-12-003. Check specialist suppliers for genuine replacements and fit guidance.
