This is my latest attempt at a 3 link suspension rock crawler. I put drive shafts on this one. I gave up on the telescoping drive shaft and decided on a solid shaft. Tried to build it without shocks but there was WAY too much lateral movement so the shocks had to go on. The shocks cut the travel significantly but that's ok. I cant figure out how to put a steering shaft on it though. With the free floating axle it's hard to get the geometry right. The drive shafts are just connected to each other in the chassis. No drive gear or motor yet. Any suggestions on hooking up the steering would be great! Don't forget to comment if you have an opinion. That's the only way to be heard!

Quoting George Staples Looks like a great start. You might consider a pendular suspension system. Or If you want to put steering in this one, you could mount the steer motor on the axle as to eliminate the steering shaft. If you don't want to do that, I would suggest running the steer shaft right next to the drive, or up one of the linkages.
Thanks! I have considered the pendular suspension set up but it just looks so limiting. The motor on the axle housing is something I've also been playing with but I think I will have to scale up my builds to incorporate all the extras that go with it. The smaller scale of my builds so far has allowed me to keep that "campy" toy like style rather than aiming for the super realism that seems to be the trend lately. Besides, I don't think I've got the eye for that kind of realism.
