su-27 launch maverick or gbu

[peyvolt]

Any bodies knows how can I launch a maverick or gbu with su-27?anideas? I have told this because I´m creting f-18 hornet with a cockpit and I want to know this question, because when I start a mission and I select maverick I don´t know if it is working or not, because I ca´nt launch maverick or gbu, thank you
