If you can fly purty well with the Kaos and cloud dancer a biplane is not a stretch--- (What kind of biplane do you have?)

There are docile biplanes and wild biplanes we need more info. on the model-

Assuming the tail moment is close (Most biplanes are-) make sure you set the CG and control throws on the conservative side- Too much elevator and... [X(]

Maybe have someone trim fly it for ya?

I have flown many biplanes and the Ultimate was the smoothest- Tell us what you got and info. will flow-
