( first pic is the extension scotch taped to the tail. it is a help with the trimming by being flexable. Pic 2 is the distance looking from the launch point top the bush it hit. pic 3 it slightly zoomed showing the position of the glider)

No need to send it, I'm working on several changes to find the balance myself. With you modifying the rudder, that saves a step already.
Because the fuselage acts like a rudder (Flat all the way) the rudder has to overcome the effects up forward from what the nose wants to steer. Anything forward of the CG/Neutral point is un-stabilizing. By making the rudder bigger you can eventually overcome the nose effects, but from what I see you're doing, why not make the nose/fuselage slight shorter (height wise). Loose a little weight instead of gaining?
To make the rudder bigger means weight gain, from the bigger rudder, but far more damaging is the weight to balance that will need added to the front.
I'm working on some mods, should be able to print and test tonight, if I get them done.
