Curved turnouts can be tricky to lay out. I've found it easier to draw the
routes I want the track to take then just see what kind of turnout is needed to
fit them instead of trying to place a stock turnout into the track plan. Going
from inside to outside tracks usually is easier if you use a straight section
thru the frog to increase the rate of separation, a completely curved turnout
can take a lot of space to diverge the 3 inches necessary for S scale double
tracks. The BK kits are basically just rail parts roughly assembled on
temporary straps so it's not much harder to lay out your routes, measure the
frog angle needed then either build or buy it and the points then assemble it.
