As others have posted, learning to use proportional control is very useful in FLL.  There is a Proportional Control lesson in Advanced on EV3Lessons.com and separate ones for using proportional control for line followers in the same section.

Many teams struggle with using the gyro because of two issues - drift and lag. However, teams can overcome both problems successfully.

EV3Lessons's Gyro Sensor lesson in Advanced has 4 different ways to deal with drift and explains how they work and what the tradeoffs are.

To learn to cope with Gyro Lag, the Advanced Lesson called Gyro Sensor: Turns, will be helpful.

For FLL, robust solutions require combinations of software and hardware - driving straight, but then also finding a line or bumping into a mission model on purpose.

If teams in VA-DC have other topics and solutions to either of these problems to share with other teams, feel free to contact us.

Regards,
EV3Lessons
