When
building flying wing slope planes just a little extra finishing weight
makes them go tailheavy quite easily.Same story withEeuropa
stabialtors.
Going forwardadding an extra weight if you
have space or making them out of lead or with tungsten inserts or both
should not cause you much problem.
I don't know where your CG
comes in at, but if you are tending towards nose heavy, perhaps consider
making a synergistic harmonazation, add a little tailweight and remove
about 15% of the stresses on the mass balance arm and stabilator drive
pins?

compared to just adding weight to mass balance arm which will increase
stresses on pins.
