|  Torque Twist, Here we go again
So let me see if I can give a breakdown of what I have been going through lately. I was working with a terribly stiff truck that performed poorly but had no TT. After reading a ton of other threads, I softened the shocks and got no advantage. I then went full circle and moved the lower links in, took out the firm internal springs in my shocks and added 50 wt oil all the way around. Now I have a truck that will twist off a coke bottle top, but the TT was so bad I could not climb a marble without throwing up the right front and flipping. Well I firmed up the left rear, mirrored my tranny, and 4 linked the rear end. Now my truck is much better but maybe not quite as good as far as articulation at the rear axle. I am still getting a slight hint of TT though. Here is my point. I am starting to think that a little TT is part of life with the RC crawlers, and as long as the truck performs fine then it is something to live with. Does this sound about right?

I put these in the rear axle and it helped reduce TT quite a bit. Read the description, kinda explains the setup benefits. http://www.rpphobby.com/product_p/ax30402.htm | |

So you 4 linked the rear, but did you raise the left upper link on the axle end or drop it on the chassis end? This will do alot for TT. And a little bit of TT is always going to be there...just part of the fun of owning a shafty.  | |

| What was that about the left side?
I read your post and you lost me a bit. Regarding the chassis or the axle ends can you post a pic as to what you are talking about? Thanks.

 You'll notice I've got a little bit more preload on the left shock...but not a lot. I'm running the same springs all the way around, with all the same shock oil (30wt I think...). This thing would float like a cloud over the rocks. Very little TT too. All the rigs I build have the links set up this way (more or less) and it makes a huge difference. Along with raising that end, you can lower the other end on the chassis also. If you haven't, read the big monster thread on TT and link setup. It took me a while to absorb all the info there, but its a must-read. | |

| Thanks.
That helps a ton. I will do that tomorrow. I think the TT in my setup is totally much less than it had been.
