And the C.G is the most important factor how the airplane reacts
to the elevator with.
TF FW190 tends to be tail heavy( short tail moment) that will result
too sensitive responce to the elevator throw.
There are some points we have to check before the flight, weight
and C.G, incidence of the wing, control surface throw, engine
power and thrust line, main gear position relative to the C.G, etc.
Some are designed by the kit maker and the rest (weight and C.G,
control surface throw) veries depending on the builders so we have
to check ourselves.
