Kang,
To increase duration indoor models are generally flown at the edge of their
stability limits. For many years this has meant flying the models just short
of a stall. In the last 3 or 4 years several of the top indoor flyers are
been building models with just short of negative static stability margins in
the hopes of increasing duration. In the majority of cases these models have
been successful. I think the consensus now is that along as the static
stability margin is non-negative the model will be stable enough for the
calm air that we fly in.
I hope that helps,
Nick
