Ah yes... badass climbs into a Jet Ranger to escape, good guys chase and shoot at/launch missile at it, and it magically turns into a Hughes 500 before it explodes.It's worse than that - there's plenty of movies where the cuts of the heroes/"cavalry to the rescue" flight from external close-up to long-shot and back feature entirely different aircraft types.
(...probably because R/C H500s are widely available and have plenty of space inside for pyro...)
