I believe they mentioned they put the 8S system into their Infraction so I would assume they used the 6100AT receiver in it which has a gyro - I doubt they would have used anything else outside of the HH brand portfolioI really want a gyro to work as it will make speed runs so much easier, but anything over 15% on the Radiolink or YeahRacing gyros I own and the vibrations of the motor make the thing wobble the steering back and forth. Anything below 15% and you don’t get any noticeable correction.
