Special Designed Helicopter with Auto Stabilizing System - Walkera 4F180 Four-Blades Rotor Helicopter
4F180 and 4F200 are very unique models, they feature a special Four-Blades Rotor (Three-Blades for 4F200) and a Tri-Blade Tail Rotor which has very few competitors on the market, combining the Auto Stabilizing System (3-Axis Gyro), it performs amazingly stable! However, The 4F180 is a "Fixed Pitch" Helicopter, but it's different from ordinary fixed pitch main blades, they do not have a fixed curve shape, they are the same blades used on Collective Pitch helicopter, pitch is controlled by a Push Rod. Thanks to the Four-Rotor Head Design, it generates great lift, we feel the perform just like a Co-Axial Helicopter, we would say it is a very interesting model.
