This is not true! Most biplanes does not exhibit this!!! If you turn right (using aileron and elevator) the plane should turn right!
If a plane turns in the opposite direction it has too high wing loading...sometimes enhanced by a warped wing! That's what we call a snap roll!
The only time you can experience adverse yaw in a model airplane is when you fly a big, slow flying, flat bottomed airplane like a big CUB!
