well this seems to be the only fourn soley devoted to this type of aircraft
so i have a question for you who are more experienced than i

i have a giles 202 by greatplanes
in order for it to be balanced it would take 2 more ounces on the tail(61 sf)
but i can fly it the way it is
my problem is that any more than a breath of elevator and it snaps
what can i do to fix this so i can get started into aerobatics with this baby

one more
i also have a 60 size cap 21
it has a 60 inch wingspan and a foam core wing
but i don't know the cg
i'm guessing 33.333 % of the wing cord at the fuse am i right?

any info on these would be helpful
