Center diff and diff lubes

[Power Adder]

Hey, I am new to the 1/8 buggy scene and am wondering what diff lubes should i start with. In the center I have heard that 30k is good but what about racing? I have no idea on what for the front and read diff. All help is appreciated. (It will be in a hyper 7 pro)

You usually have to run a bit heavier diff lube in the center if your are using motor brakes (I assume you are). I run 10K in the center of my buggy (about 7.6 lbs) and it stops great. It worked OK with the stock 7K, but I got a bit better acceleration and more consistent braking with the 10K. I run 30K in my heavy (12 lbs) Muggy, any less and it won't stop. For racing you will likely want as much diff action as you can get (lowest weight), and still stop well.

I just run a similar setup to what the nitro guys are using... typical buggy oils are in the
5-7-2 ballpark, give or take a little. I wouldn't go over 10k in the center. 7-10-3 is probably the heaviest I would try.

Common starting point for truggies seem to run about 7-10-3... but some do go heavier.

I have not experimented that much with the diff fluids, but I'm going to this summer a lot more.

On my electric losi 8ight I run 10K in the center with good results.

Cool so 7k in the rear 10k in the center and 5k in the front

7K in front, 10k in middle, 5k rear

Hevier oil in back means loose rear (oversteer on power) and understeer on offpower.

But difficult to recommend all depends from your taste just experiment

Start with lighter oil and go heavier. Usualy rule for novice drivers F/M/R=Heavy/Heavier/Light

Actualy I am use 7k front, 30k middle, 1k rear
I have tight track lots of 180 degree turns so for me realy important offpower steering, and heavy oil in middle gives me oportunity to oversteer, slide in corners then i need it.

I'm pretty sure it's 7 front, 10 center, 5 rear.

Ussually it's heaviest in the middle, 2nd heaviest in the front, and lightest in the rear. So if those are the oils you have it'd be 10k middle, 7k front, and 5k rear. Although 5k in the back and 7k in the front are fairly heavy for a buggy. I wouldn't go heavier than that, maybe try 5k in the front and 3k in the back like others have suggested. Good luck!

O my bad so lighter oil in back gives me less oversteer and heiver oil means more understeer

Not exactly ONPOWER and OFFPOWER factor here also
With hevier oil back Onpower it oversteer (your buggy tends to loose your back starts to slide) Offpower it understeer (you feel that your buggy not steer well like it supposed to)
Some basics you will find here also http://users.pandora.be/elvo/ its for onroad car but basics are same
