HI oLGOAT, What biplane is it? I have 4 Bipes now and are not really hard to fly if well set up. As suggested, really check the plane out for CG, MODEST throws on elevator and ailerons (especially if there are upper and lower wing ailerons). Once you are more comfortable you can crank them up. Not a bad idea to check wing incidence too. Definately have an experienced pilot check it out for you Good luck, I hope you are successful, you"ll love it.
