I recently built a new rig with an SPV2 chassis w/ Wheely King axles,trans and motor. The articulation is almost perfect, not too much and not too little. The problem I am having now is torque twist. its not enough that it lifts the wheel, (front's are weighted) but the chassis itself is twisting and unloads my shocks. I have moved the links around and had no luck. If someone could take a look at my rig and give me some advice, it would be greatly appreciated. Thanks.

Its been my experience that TT is more easily controlled with shock settings than link settings. Make sure your springs and oil arent too light as a start. Without a belly shot its hard to check out your link mounting positions.

Here is a belly shot - now that I think about it, i think my lower links may be too far apart.

I actually answered my own question...lol. I moved my lower links in which created a reverse triangulation and damn near eliminated all of the torque twist. The remaining bit thats left should be corrected by adding some internal springs to my shocks and increasing the weight of the shock oil.

Good news you got it sorted so easy. I found upping the shock oil to 80w on my axial to really help with the same situation. Going to a full spring shock setup will also rectify the problem I found ;)

yup thats exactly the way to do it, now play with your upper links at the frame end changing the virtical distance between them upper and lowrs, this will change your squat/anti-squate and you will probably be able to get that last little bit to go away

also, if you run your rear links asemetrical, i.e the left slightly higher than the right, it eliminate tt as well.

id suggest doin that prior to takin shocks apart and getting covered in oil

More distance apart at frame = squat
More distance apart at axle= anti-squat
And by double triangulating the links you also have created little or no axle steer during articulation.

Thanks for all of the tips. I moved my lower links in, used internal springs in my shocks and added 80 weight shock oil. Everything seems to be perfect at the moment. Took it out for a test this afternoon and to my surprise my rig works perfect. no TT at all. Thanks for all of the tips!
