A great power plant for heavy cars or super high bite track surfaces, the R3.0 series of 4 Pole motors have been winning races since their introduction in 2018. With 4 pole rotors and 12 segment stators, this series accelerates heavy cars such as SC Modified cars in Oval racing extremely well, outpacing their 2 pole cousins. May also be useful in lighter cars, such as 1/10th scale Late Model, on carpet tracks.
All these motors come with 5mm shaft for the demands of these heavy cars. All the variants have zero, fixed timing; add 25 degrees in your ESC as a starting point (watch your temperature, do not exceed 160 degrees F).
