This motor is a brushed motor so be aware that some time you will need to change the burned brusses. Its a great first upgrade from your stock motor or the light super tuned motor or the 540 spor tuned motor. Its definately faster that the previous motors but not faster than the tamiya super stock motor TZ witch is the fastest among the tamiyas brushed motors. The good thing about all these motor inclusiv this one as well is that you dont need to change your electronic spped control ESC because they can work perfectly with the stock ESC as long as your stock is brushed. All tamiya tt-01 models included type E type D or type R work with brushed stock motors. So its a cheap and easy way to upgrade but dont forget to replace the bearings before assemble this motor. My advice is to buy along with the motor spur gears 55T and 58T and pinion gears 23 and 25 so you can make combination with this motor. Place this motor with 25 pinion and 55 spur gear or with 23 pinion and 58 spur gear and decide whats best for your running type. Thats all for the brushed motors and when you get red of it then try to upgrade more with brushless motors and ESC. Excellent motor for first upgrade dont expect your car to ''fly''.
