yes you need some radius but that radius depends on the weight and weave of the cloth.. if you're using something like 6oz tape an 1/8" to 3/16" is about right.. just make a test piece first.. if the radius is too small the tape will lift way from the surface just past the edge of the radius area.. if it stays in contact you're good.. 45/45 bias tape will lay over a tighter radius than regular 90/90..
