I still had the balance set slightly nose heavy so I am sure this played a role. Even so I could knife edge circle using only rudder input. i am sur ethat with a more rearward CG that the belly tuck will be less pronouced. In AdrianM's thread on this model he reflects on being able to virtually knife edge loop - only inhibited by the piolt aprehension.

Go ahead and get the kit while you can - it will be good to compare to your Goldberg one anyway ....

Here is the link to the rebuild (I hope).
