Umm... With a tighter front diff won't we get lees steering?

Well yes and no. A tighter front diff will give you less off power turn in but more on power steering going in or coming out of a corner.

Could you explain why?

Go to this link and start at page 35 and read about set up. It will apply to the BX as well........

Well, I'm not able to open de JConcepts file. Regarding the Losi's one, it says the same as you posted.

I don't preted to be wiser than anyone, but I'd why to understand why this happen. COuld someone explain why this happen, please?

Entering a turn: A tighter front diff will give less and thus the tires will not roll as easily off power. Just like in a real car, if your front tires lock up you can't steer even if they are turned all the way. The same principle applies. The tighter the front diff, the more the tires try to "lock up" off power. This results in less off power steering.

Exiting a turn: By the same principle, a tighter front diff will slip less on power, resulting in more power transferred to the tires and (assuming there's adequate traction) the front tires will pull the car through the corner on power.

This is why a one-way gives you greater on and off power steering. It free-wheels off power and it's like a fully locked diff on power.

Hope I didn't confuse you further.

Great reply. I could not have done it in that few words but you said it all........

Hi guys, it's always a pleasure to talk with you!

I undersand what you said, however, I have some doubts:

Exiting turns: As far as a tighter diff will make both wheels spin at more simillar velocities, the inner wheel should push the car out of the turn.

I'm just wondering about it, I'm not talkng about traction and grip, but turning radius.

I'll try to show it in other words: Asumming that diff doesn't "unload" under aceleration, a softer one will allow tigjter turning radius. Does this make sense?

Well try it both ways and let us no how it went.
