Need Leasons about Axle Types

[george]

Hello Again

This is George, I am New here, most of my time/money is spent on R.C military ships, submarine and tanks.

I have been researching a couple of scratch build vehicle projects BUT I am getting stuck on the axle part.

Can someone explain a few points about axle technology? From what I see there are LOTS of "locked" front and rear axles, to me that means that both wheels turn at the same speed in turns, Y/N ? I hear that`s Great for rock crawling BUT how is the handling on regular flat surfaces, dirt, grass, slight smooth inclines?

I seem to be unable to find any, for lack of a proper word, unlocked axles, are they available? I would like to know since I am looking for either 1/18 or 1/10 for the 4x4 projects I mentioned and only front steering.

Any leasons you can share and sources you can point me to would be greatly appreciated.

Thanks
George
