About T-MOTOR AT4120 VTOL Fixed Wing Airplane Long Shaft Motor

High quality AT4120 BLDC motor has been developed especially for use with 5s and 6s lipols for 3D models up to 3500g and for sailplanes up to 5000g in weight.

And especially the 250KV can work under 12S lipols with 2100W max. power. Recommended to be used with T-MOTOR AT115A and T-MOTOR FS15*8 folding propellers.

AT4120 Highlights:

The AT4120 long-shaft engine adopts a long-shaft design, which improves installation flexibility and compatibility with different types of propellers and accessories.

This makes it a versatile choice for different types of aviation applications.
