I see there are benefits to both style of chassis using a laydown and a vertical tranny. The laydown gets the motor weight lower and the vertical tranny mount keeps the weight centered. This may be a personal preference question, but is there a style which is definetly better than the other?

Thanks.

The lay down design is better for a comp rig.

What about the weight off-set? Do you find that your rig tips easier on the side the motor hangs over? Or do you try to balance out the weight by adding electronics, etc. to the opposite side.

Bender: PM about your chassis.

well you could add all the electronics to the other side or use a thicker oil on the side where the motor is or use stiffer springs.

The motor hangs out of the chassis on the torque twist side, I use a stiffer spring and oil in that shock anyway. It probably does side hill a little better one way then the other, but it's nothing that's real noticeable. Motor low in the chassis wins over high in the chassis everytime, even if the bulk of the weight is a little off center, IMO.

I'm building my first crawler from scratch and have left the chassis til last and I'm kind of glad I've not put the motor so far off to one side that it hangs out of the chassis because it would lenghthen the bottom of my chassis considerably, push my bottom link mounting points apart and force me to shorten the bottom links a bit.

I'm not saying it can't be done, because obviously a lot of people have successfully come up with chassis designs that have the motor hanging out of the side on their comp proven rigs. It's just that in my case as a noob, it's much easier to leave the motor a little higher to clear up some chassis side plate space for mounting points and drill several holes to experiment with.

does a vertical tranny setup work ok in a trail rig though?

Does anyone have a used verdical or laydown chassis for a tlt, im new and i have the stampeed tranny,tlt axles,masher 2000 tires,ect- i have fifty bucks

I have run them both, and I would have to agree with Bender laydown is the way to go. With a laydown you can get more GC without sacrificing a high CG...
