Center of Gravity
The Sukhoi has a large CG range for different flying styles. Our CG is set at
10mm behind the center of the wing tube and is Ideal for precision IMAC flying
and is a safe starting point. The proto-type is being flown at about 2” behind this
point. Start at the forward CG and move back slowly at your own risk.

Mixing:
The Sukhoi requires very little mixing to keep it tracking nicely. There are lots of
things that will influence the amount of mixing required. But as an indication, the
only mix we required during our test flight was 5% up elevator for knife edge flight,
no aileron mixing was required.
