The new generation of AXI 4120 / xx V2 has higher performance thanks to its sophisticated design, which in conjunction with an integrated cooling system based on the principle of a turbine effect airflow keeps the motor windings cooler by up to 20%. The engine is also due to new store magnets shorter, lighter and mechanically stable.

Robust and reliable high-performance brushless motors AXI 4120 / xx with rotating drum and neodymium magnets have a hardened steel shaft with a diameter of 6 mm mounted in three ball bearings, which ensure very good mechanical stability under normal and inverted mounting and allows high dynamic loads common in aerobatic flying and ensuring a very high durability. Rotors AXI 4120 / xx are exported to most modern dynamic balancing equipment from a reputable company Schenck. High-quality Japanese bearings supplied to the engines of the V2 is characterized by higher durability and quiet operation.

AXI 4120 / xx V2, thanks to its great to torque suitable for large propellers without the need for a gearbox, which ensures high efficiency of the entire drive.
