Will the Walkera 4B120 cope with indoor flying?

Due to its rotor diameter and 3D capability, indoor flying is only suitable in large halls with plenty of clearance. Outdoors in calm conditions is preferable for routine practice.

What should I check before each flight?

Quick pre flight checks include blade condition, secure linkages, transmitter binding status and battery voltage. Confirm the gyro is responding normally on power up.

Is tuning the gyro necessary for better performance?

Basic gyro settings are usually fine to start with, but small adjustments can reduce oscillation and improve control crispness as you refine flying style.

How do I source genuine spare parts?

Refer to part numbers listed in the specifications when ordering replacements, and use reputable Walkera parts suppliers to ensure correct fit and performance.
