Also to be noted... in real plane that "inboard/outboard" pylon switch only alters the sequence. from 1,2,3,4,5,6 to 5,6,3,4,1,2.
WCS will of course help with selection as well.. for example, if "inboard" is selected, and target is under the Dmin for R27, it will autoselect short range missile...
More recent mig29 versions have updated throttle quadrants with more controls on them.
