bad news,

i moved the 3 servos from rear bay to front compartment,
the three servos weigh 11 ounces.

i had 15 ounces of weight under gas tank,
and another 3 ounces in cowl area.

after moving everything

i see it is maybe not tail heavy now, maybe,,

but i still have to use the 15 + 3 ounces

i was hoping i could use less weights,

i also checked that the surfaces on bottom side of ailerons and elevator were flush.

good news is that now, when i do CG test, the nose is slightly lower than tail, and the top of wing is completely parallel with the floor.<br type="_moz" />
