Diff oil confusion

[rcsammy]

I made a similar post a while ago but didnt get much interest.

Im running a converted X1CR and I have been struggling to find a good diff oil setup for it

I tried 7-10-4 to start with which handled well in the corners but the front wheels would spin up alot on acceleration

I was then recommended to try 30-50-20 so i did and its awfull goes like a rocket in a straight line but the slightest touch of steering and its flipped over


So if i go back to my 7-10-4 setup, if i want to stop the front spinning up what should i change?
Or could any other 1/8 buggy leccy owners share their setups?

Thanks
