Help Expeirence on Triple Diff setups ONROAD

[Unsullied_Spy]

I'd get the center diff as close to locked as you can get, maybe even pack it with silly putty. One of my Hyper 7s is setup for onroad and even with 30k weight in the center it unloads the fronts like mad and understeers horribly. Start with 7k in the front and go stiffer if it still doesn't handle quite right step up to 10k, I like my rear diff to be pretty loose so I usually just pack them with automotive wheel bearing grease (once it breaks down it lubricates very well but isn't too stiff) but 3-5k should be good for the rear.

If your going to just bash up and down the street the heavy center diff oil will help get you the best forward traction, but if you are planning to run and actual course with turns and all then you will probably want to run lighter center diff oil to get the car to handle better. It might take a little experimentation to find what you like. Balance forward traction with turning.

Have a look at serpents, kyosho evolvas and the like they don't use diffs at all, and there scary fast.

thanks, I have a locked center now, maybe I will just change the rear to 5k and give it a run and see. The big gas guys use heavy auto grease or 100k.
I'll give a looksy at Serpents

Thanks, I will try that. My front has thick STP oil in it, probably equal to 5k.

I actually am close to the 1/5 scale track races and want to practice on and maybe someday race a 1/5 2wd gas.


Thank you guys
