Why is dynamic balance essential on DJI Agras T40 and T50 propellers?

The massive 54-inch folding blades on the Agras T40 and T50 rotate at high tip velocities under heavy payload weights (up to 50kg). An imbalance of just 0.1g generates extreme radial vibrations that destroy motor bearings, induce flight controller IMU clipping, and cause unexpected motor esc cutoffs mid-flight.

Are agricultural drone propellers subject to export restrictions?

No. Civil agricultural folding propeller blades are classified under HS 8807.30 (Parts of civil unmanned aircraft) and HS 3926.90. They are fully compliant civil agricultural parts dispatched globally via commercial express carriers.

How do I verify propeller dynamic balance after replacement?

Run the motors at 30% throttle with blades folded, then unfolded. Excessive frame vibration unfolded indicates imbalance beyond 0.05g - replace the matched pair.

Are 5413 and 5415 blades interchangeable?

No. 5413 is the CW (clockwise) blade and 5415 is CCW. Each arm needs its correct type; mixing them causes immediate flight controller rejection or crash.

Technical FAQ: Agras Blade Replacement

Q: Can I replace just one single blade on a CW/CCW rotor pair?

Never recommended. Even minor weight discrepancies between unmatched blades cause rotational flutter. Always replace folding blades in matched pairs to ensure uniform aerodynamic lift and preserve motor bearing integrity.
