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.
