  • Getting a Crawler - Power Question

    Guys, I'm going to be picking up an Axial SCX10 II Chevy Blazer in the near future, and I'm confused about something and was hoping maybe you had an opinion on it:

    If the ESC is 3S Lipo compatible, does that mean the whole system is 3S compatible? Meaning, is a 3S Lipo going to cause more wear to my car than a 2S? Does that put too much power through the servo, or other potentially sensitive parts?

    Follow up: would a 2S Lipo be a better fit over a 3S?

    Both the ESC and the motor would need to be 3S capable to be able to use 3S. 3S will for sure cause more wear and tear on the drivetrain but the crawler will be faster and have more power. The ESC will limit how many volts that go to the receiver since they come with a built-in BEC. The receiver than powers the servo.

        Here is a good crawler forum. Loads of information and guys/gals with plenty of experience. Check it out!

          In case you didn’t already know a 3S compatible setup will run on 2S with out any issues

            Since you're getting the Axial, I'd recommend you stick with a 2S battery.
            I say this on account the stock motor in the Axial is pretty fast with a 2S battery, and adding a 3S battery to it will make it even faster. Faster than you really need to go for a crawler.
            Just my honest opinion....

              That was a thing I was curious about. While I think more torque would be cool, more speed wouldn't, at least not for me. Thanks for clarifying that, dungeonracer.

              I appreciate the tips, 4424ever and Rooster. I think I'm going to go with a 2S.
