Wondering what radio to run in your RC car? Two radios lead by a wide margin in nearly every kind of racing: the FlySky Noble NB4 and the Sanwa M17. We counted the setups saved in the RC Setup App since January 2024: 2,189 racers named a radio, across off-road, touring, drift, oval and more. By brand, Sanwa leads with 34% of them, followed by Futaba at 29% and FlySky at 25%.
The percentage under each radio is the share of racers who run it. Several of these are older models, so where one has been replaced, the button goes to the radio that replaced it and the blurb says so. Counts updated November 2026.
Buy links to AMain may earn us a commission. That doesn't change the order: racers decide that.

How we counted
We count anonymous totals from setups saved in the app for every kind of racing, nitro and electric. A racer counts once per radio no matter how many setups they've saved, and a value only counts if the racer entered it themselves, not if it came along with a copied setup. A racer who runs more than one class counts once in the list and once in each class. Different generations of the same radio, like the NB4, NB4+ and NB4 Pro, are counted together, and the blurb gives the split where racers named one. Racers who named only a brand count toward the brand totals but not a radio. Ready-to-run radios, like the Traxxas TQi, aren't in the list. Specs come from the store listing for the radio each button goes to.
