Default WHY don't any Stadium Trucks have a Bevel Diff ??

Ok I have been racing Nitro and Electric Trucks for the past 7 yrs.

Now I race 8th scale and race my AD2 now and again.

I have no problems with my AD2 diff .

I was watching a heat of Stadiums at my local track and could hear the diffs slipping on our 8th scale track which is a common problem. Yes I know if the diff is built right and the slipper is set for a little slip this would not happen.

WHY dont any manufactory build them with a sealed bevell diff that is bullet proof and can be tuned with diff oil like a 8th scale. ????

The only down side that I can think of is the bevell diff would be a little heavier.. Todays motors are so powerfull you dont need to worry about it.
I run a basic Novarossi that is side exhaust and just 1 HP which is more than enough.

What are your thoughts???

The simple answers are to much weight and a ball diff is more efficient.

Ball diffs have less drag , lighter , more efficient , and faster to work on . Losi has a few trucks with gear diffs that can be filled with diff lube but don`t hold up well in racing .

Will the gear diffs be more durable racing these little trucks on the 1/8 tracks? I see it as a possibility. I just might have to try it on one of my gas trucks one of these days.
