Vertical Rudder Assist (Apply 20~50 cc Airplane) 

Have you experienced hovering during crabbing? You will feel it if you install with rudder assist. 
We have tested, it could be very slow when crabbing, to make the rudder control surface bigger 
and give a bit push to the gas, then you can see the plane will be Climbing and hovering. 
The most important thingis that its rudder control surface is efficient,to turn the hovering is easygoing with quick reaction.. You must get more impression to judge whafsthe difference between having Rudder Assist and without when it's crabbing. 
The plane noramlly has a flabby rudder control surface which causes the slow reaction. But installing with rudder assist will bring the great feeling of active flight and there is no hesitate with 3D action。here is no hesitate with 3D action。
