This time let's go back to basic with the topic of gearing.
I'd like to introduce 2 things in this video. First, gear mesh, what is it and how to set it.
The other thing is gear ratio, what is it and how it works.

And there is also a simple mod for WLtoys 1/28 K989, K969, etc.. as well.
With this mod you can use almost any pinion and spur combination even the ones that bigger or smaller than the official gears from WLtoys.
