I understand how frustrated you are, but I wish I was in your shoes with such a beautiful plane to work with. If it does come down to adding some weight to the nose, tungsten might be a way to go and I only mention it because it is very expensive and would not be doable with a lesser model, but in the space of about two standard receivers you can have about 2-2.5 lbs. Bucking bars used for full size planes can be ordered in tungsten, but expensive!
