Bill,
I though your tandem was ~5" chord on wing and stab right? I am talking
about 8" or so chord wing and a 5" chord stab. Then with about a 1" nose
leaves about 4" from the trailing edge of the wing and leading edge of
the stab. They start to act different that close coupled. I always
thought 8" chord monplane like that out cruised a biplane. They can do
good time from low height, trying to get them to climb, cruise and
descend is when the fun starts. The last USIC I attended at ETSU my dad
an I had two identical 8" OPP models built, we both tried independently
to get them to climb, cruise, and descend properly then tried to mix and
match what we were doing. CG, total incidence, incidence distribution
from wing to tail etc. We usually could get 2 of 3, by the end of the
contest we decided we needed my dads climb out and beginning of the
cruise and my models mid cruise and descent to win :-)
