If you're looking for full-match alignment and can't get it from your gyro or encoders, consider if your strategy puts you up against a wall or other well-defined feature of the field on a regular basis, and see if you can use that as an opportunity for a heading correction.

We actually had our NavMXP gyro running for over 20 minutes with only 1 degree of error the whole time. The NavMXP Gyro has been one of the most awesome finds I have had for the years that I have been coaching. I did a little work to the code from NavMXP but I do not see drift specially in the two minutes of the game. Our auto went 12 for 12 at world championships and was about 95% the rest of the year. We turned and drove straight many times throughout the match. The old kit of parts gyro was a waist of time. I am tell everyone that I see that this one is for real.
