I think your local track surface is more to blame for that(from personal experince in Feilding). Electric Offroads making a bit of a resurgence in NZ and if the tracks get as good as they used to be...it'll be fine.

It's just unfortunate that the 8th scale cars popular at the moment do rip the surface up as much as they do. It creates a lot more loose material that in the old days simply never appeared.

Previously there was usually very little dirt, let alone dust on the cars as the tracks held up much better to the comparitively little abuse older electric cars could dish out.

Also my desire to go more off-road then what a track usually offers.

And yeah, I have a bone to pick with those 1/8 buggies

And while your points are entirely on the money, I just wouldn't consider this new design suitable for off-road,There are fare more suitable designs.

But that's just my opinion, And I have been way off in the past.......

Here in my part of the world ( Western Canada) it's the same problem.
Our tracks get ripped up by 8th scale buggies and truggies, so unless the drive train is sealed it's asking for trouble.

Default wide vs narrow

What about the BJ4WE makes it clunky? Is width the only thing that matters? Considering that the CAT has side by side batteries, it can only be as much narrower as the gap between the cells. Compared to the BJ4WE, that's less than half an inch.

Everything is a compromise, and considering the trade-offs is what the design process is all about. The mass needs to go somewhere, so there are two options:
1) Stretch the weight from front to back along the centerline of the car. This will hinder front to back weight transfer, which will hurt the car on rough tracks.
2) Raise the weight higher. Most of the slim cars you refer to have taken this approach. The driveline (rotating mass) is higher, and the batteries are underneath it. Others stand the servo upright, mount the speed control or receiver on top of the servo, etc. If given the option, I would choose low and wide over tall and narrow every time.

And as the battery is the single heaviest item of any electric rc car, it's positioning is pretty important I'd say.

Mind you, 4WD cars be they touring or off road certainly have to consider the rear to front drivetrain. Look at all the newest tourers, it's all about getting the drivelive down as low as possible.

Also agree with Brad R that low and wide is preferable to me over tall and narrow.
