what is the front to back balance point for a biplane ?
I know on a monoplane the balance point is 1/3 back from the leading edge of the wing but with a biplane that has it's wings not set directly one over the other, how would you establish what the balance point would be ?

It's usually around 25% of the mean chord of both wings superimposed on one another when viewed from the top. Normally, the top wing is staggered a little ahead of the lower wing. It is also set a little higher angle of incidence, to make stalls a little more gentle. top/front wing stalls first, easy to recover before a total stall and spin. The wings interfere with each other. The lift from the top and bottom wing are not the same as it would be from a monoplane. The balance point is still about the same as monoplane, but with complications.

Long answer short.....it moves depending on weight of pilot and passenger, also the weight of the fuel. As you burn off fuel, it tends to move forward.
