Bs halfcab is done from fakie and there's no flip in it unless its a halfcab flip. Use your arms to get the 180 spinning and look where you want to land. The turn comes same time as you jump

Before you do an Ollie in a position of doing a 180 then do the Ollie and turn at the same time

You don’t have to flip unless you want to do a half cab flip

Its not flip :)
