I disagree... having tested gyros with my KO Propo EX1 about 5-6 years ago, I was able to drift around corners and carry speed that I could never do without the gyro. It was like taking candy from a baby on a loose pack track to the point where I lapped the entire field. Folks were amazed at how much of a difference it made, and I easily got TQ, but disabled the gyro during the main and only then was it a very tight race, I think I finished 3rd that day (without the gyro assist)... folks were always asking me if I was running the gyro on days when I was running fast.

What I have learned is that you need very little gain, anywhere from 5% to 15% max... too much gain will cause more harm than good, and it's a variable depending on amount of traction... so the looser the surface, the less gain you need... as traction picks up you can increase the gain to a point of diminishing return where medium to high grip tracks are essentially useless to have any gyro assist.
