edge asked 4 months ago

Hello

I’m quite now to the RC world and amazed by the nice details of the different open source projects.

I do want to start my own OpenRC design, but I’m not sure what gearbox ratio to use. (2 stage)

(Ofc I want to print the gears.)

I’m also targeting a 1/10th model scale, truggy style/usage.

I do have:

  • wheels: 110 mm
  • diff will propably by: 1:2 ratio.
  • motor: “540 Motor 60A ESC Carbon Brushed Shaft 3.175mm For 1/10 RC Car” (from banggood)
  • battery: 11.7 Volt

I’ve no clue what this motor speed is and what speed to target, with printed gears..

Thanks for any detaild information.

Hello edge,

As far as the OpenRC Truggy goes you find the spec sheet here for reference. You can also have a look at the OpenRC Truggy Gearbox by Thingiverse user "hylpro".
