Curiosity got the better of me. So i gave the short course truck a proper couple runs with the centre diff. So the clutch i took out sends even power to the front and rear diffs. The centre diff is pretty loose and does the open centre diff thing of sending power to the path of least resistance. Both the front and rear diffs are pretty loose open centres. So path of least resistance went from just left to right, to front rear left to right.
So yes this thing is 4wd. But by design its supposed to be more towards dirt or gravel not 4x4 stuff. That being said. On flattish grass and dirt it handles quite a lot better.
On obsicles that are more 4x4 like, its a turd on a stick. It used to just just be a turd and spin the 1 front and 1 rear tyre that had least traction. With a centre diff it just spins the 1 tyre with least traction.
Not upset about that at all, it handles going fast a heap better now even though it wasnt too bad before.
