Hi Krossk
Why would you add 2 inchs on the rudder , I know that it would be for more control for the tail surface . From hear-say and seeing it the the tiger is tail heavy , because it s fusaloge is long . A friend of mine built his and with regular tri-gear , sitting on the ground (not on the cg point ) , the plane was very light on the nose . I was just wondering why ?

While the Tiger series is typically very steady tracking and capable of precision aerobatics, they are also known for weak rudder authority and poor ability to sustain knife-edge flight. (My Tiger 2 exhibited these characteristics) My intent by adding rudder is to improve rudder control. My additions are still miniscule compared to what the modification article I referenced earlier recommended. I just didn't like the way that one looked, so I am still trying to preserve the original lines.
As far as balance goes, I intend to add a built-up cowl and aluminum spinner to the nose, which should adequately offset the minimal addition to the rudder. There's also plenty of room for a large battery under the fuel tank if necessary.
