New propeller tip design, with fligt more efficiently.
After many aerodynamic simulations, the design of a large swept tip can effectively improve the vortex distribution of the tip while significantly reducing the vortex intensity, thereby achieving a double-sided improvement in pulling force and force efficiency.


Strengthened propeller root, loads increased a lot. The root structure is strengthened and combined with improved materials, which significantly increases the service life and supports high vertical pulling force and coaxial configuration.


T-Motor's unique Dam-board design
it acts as a buffer to absorb impact energy with dam-board design and reduce the probability of damage to motors when drones crash


Innovative Hub Design, Shock Absorption and Loss Prevention
The upper and lower plates are seated closely. The new stainless steel corrugated spring is added inside to improve the rotational damping and wear life of the gasket throughout its life cycle.

Rotating Shaft Screw Design Reinforces and Anti-Lossening Effectively
The aluminum rotating shaft is designed to prevent the blades from rubbing against the screws.The deep spring washer screws are combined with the self-locking nut to effectively ensure the anti-loosening function of the parts, thus eliminating possible safety implications during the flight of the blades.
