I used to get interference a lot under the airport radio tower when I’d roll by. Would do the same slowdown as @b264, even when I replaced my remotes with benchwheels, I still never fully trusted those spots (only ever had once cutout since, and I was drinking, so it’s hard to say if it really happened)
If I ever get tired of the interference, I’ll go with an old school wired remote through the ADC input. Did this on a scooter build and worked great.
