Maybe 700 is a slight over estimate… but it is at least 300…
In competition, that’s not legal. It’s a good idea for between competitions, but that takes time, and in some places zip ties may act differently than twist ties when your robot moves (zip ties are more rigid and less likely to allow wires to slide through them). Have you had any problems with your robot behaving differently at competitions than it did in testing/practice?
