    Default Rudder modification?

    Hey guys. I know on the classic 4, the rudder and stabilizer are bigger. I was just wondering if anybody has upgraded/extended the rudder on a 2? And how much it helped with stability? I'm wanting to do mine to make it a little easier to control on landings!
    Thanks
    Andy

    And ... my model I with 10" added to the vertical stab and added a model IV rudder. Made a huge difference in yaw stability:

    The builder of my model 1 added 10" to the vert stab and rudder. During my early flights (around 230 Hours on aircraft) I noticed quite a bit of deflection of the vert stab when operating the rudder at cruise (about 2 - 3 "). So I added guy wires from the rudder hinge to the rear horz strut attach bolt. This stopped the deflection and gave me the warm fuzzy feeling.
