Default motor/esc combo for 2wd losi

Im building a 2wd sct and wondering what a good motor/esc combo would work well. I've been looking at tekin and was curious what the difference is between the 17.5 and the 21.5 redline motor

What do you plan on doing with the truck? Racing? Bashing?

Either way I don't see a need for the 21.5 motor in it. With the listed specs for the Tekin Redline motor, the difference between the two motors on 7.4 volts is going to be 2,960 rpm with the 17.5 being faster. The 17.5 is listed as 2,500 rpm/volt, as the 21.5 is listed as 2,100 rpm/volt. You would have to gear the 21.5 WAY up to achieve the same speed at as the 17.5. The 17.5 is used in almost all stock classes.

I race 4x4 now wanting to add a class. At my local tracks it is just 2wd open sc. Im looking at the rs esc but wasn't sure on motor sounds like 17.5 is better option

Is the rs pro worth the extra money over the regular rs esc. Im sure it has a few more bells and whistles but does it make that much of a difference. Thanks for the advise.

Run the RS with 17.5 you dont need the pro for that motor. Pro is built for lower turn motors. I think 6.5? Something around there.

A lot of the guys I run with are using the Viper VTX10 and VTX10R esc. They tried the VST motors but never could get the speed out of them. Although Az tracks are all med/large to large. The hot motor/esc combo is the VTX10 or Tekin RS esc with the Trinity RevTech motor.

I am running the Venom 60a/3300kv combo in my xxx-sct and I couldn't be happier. It is smooth and controllable yet still very powerful and you can't be the $140 price tag.
