hi all. I have giles202, which weights 3.4kg and is powered with magnum 91fs. I want to get more rudder effect, so can cg help this problem? if i will takecg bit rear, (nowit's on main spar. want to take it 2cm rearer) will it increase rudder effect?

thanks,

You are going to make the plane more tail heavy. Any control input affecting pitch is going to make a difference from now on. In straight flight your rudder will be used to yaw I dont think you will see a huge difference other than maybe the plane being more sensitve to the elevator when it slows. However on knife edge or another 3D manuver I believe you will see a notable difference. As the plane is now tail heavy any control input to pitch weather its a knofe edge or elvator movment will heighten the controls intensity. Hope this helps. Be carful as tail heavy planes are very very thouchy and a 60 size Giles can be a handful. I had a YA Giles 300 with a Saito 100 in it and it was very snappy when it was tail heavy.
