Yep. But again - try and find out what other people are using and copy. If it is transferring so much drive to front, then thicker centre diff oil will reduce this.
You want the balance to be, generally, thick oil in front so to pull out of corner without 'diffing out', equal or thicker oil in centre so not to transfer all drive to the front and waste power wheelspinning, and thin oil in the rear so it works as a diff and can drive through a corner (not drift). I am using a Kyosho MP9 and I have got 7k 9k 2k in it (this is the way diff oils are stated: front, middle, rear). But this is particular to my car, your car is very likely to need different oils but same sort of balance.
Can I recommend to you the Hudy setup book. It really is a bible of information for things like this.
