Hi

You may also want to try 30k in the rear, 100k in the middle, and 50k in the front.

Hi

This is what I use in my E-Revo. I know it's not a Kraton but they are both 1/8 scale Truggies. "USUALLY" the 1k-10k oils are used in 1/8th scale Buggies and 10k-500k are used in 1/8th scale Truggies and Monster Trucks.

Well from what I know the Kraton comes with 7k front and rear 10k center . When you go thicker it evens out the power flow , with stock setup lots of power goes to the front wheels , I ended up going with 500k center and 100k front/rear . You can tell a diff but still on 6s power the Kraton still wheelies like crazy running Trencher X. So I really could go to 50 k rear an see how it does . In 4s it is awesome right now and that's the battery I like to run .
Ok...please help a newbe out...why different oil wt. Speed\response \durability?

so higher weight fluid keeps the front down more and reduces ballooning? or is that with lighter weight fluid?

ahh yes. i actually meant to type that :)

ok is there a performance loss (like loss of top speed/acceleration) with heavier weight?

Running Trencher x 3.8 motor and esc are stock, the motor does not get to be too hot,it has never gone into protection mode. I will try the 15t though and see how it does..
