I have had great 4 pole motors since 2018 under my brand name which won multiple race events in SC Mod & B Mod cars. But they are dated, in need of updates. For more than a year I have tested three designs which I have found unsatisfactory, and my team racers are needing something new! I am not going to sell a substandard 540 (10th scale) 4 pole motor until it passes my testing!
Until then, I recommend what I see is the best 4 pole motor for oval racing: the HOBBYWING 3652 G2!
