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.

AXI 4120/14 brushless motor V2 is learned to drive models with a flying weight of up to 4500 g with power from three to pětičlánkového Li-poly battery. Perfect for models like our heavier and faster EPP "warbird", for example. Thunderbolt and Corsair, a leading 3D Yak-55 1400 mm from Gernot Bruckmann, respectively. bigger, but slower models like the Piper Cub 1: 5 from sigue ...
Motor mounting: AXI 4120/14 V2 is designed for front and rear mounting. When front mounted behind the front motor using four M4 screws that extend into the front of the engine in the range of 4-5 mm. Motor bulkhead should be from 6-8 mm air plywood.
Set engine comprising: a brushless motor AXI 4120/14 V2 with cables carrier for fixed pitch propeller, set for rear assembly instructions.
