<p>I have completed zona tres upload once and it was really hard but I stole a chopper and completed it. I can't complete robotica raid though because they call in every drone in the base.

<p>Yeah, helicopters are very hard to fly in Just Cause 4. They're so unstable. If enemy helicopters start giving you trouble, use the grappler to retract them to the ground. Bigger helicopters may take multiple cables.
