Front & Rear Gear Differential

Do you know what is the advantage of using Front & Rear Gear Differential in 1/10 Touring?

Thanks All !!

EP touring becoming very powerful today, replace rear ball diff with rear gear diff to take the advantage of less maintenance and consistant diff effect.
Most of the player is looking for more steering by replacing front spool to front diff, with very thick diff gease, like 500k.

C Hing, thx for your comment .....

Actually, I want to try front Gear Differential with 500K.

Thanks All !!

What will be your rear diff oil then?? 100K??
Just want to know what pepole are using! I'm new to gear diff too!!

I am now using the one shown in the pic for Rear. For the front, I will try to use Kyosho 500K.

Thanks All !!

其實用 gear diff 應該係想有真車 LSD 既效果. 用gear diff oil 等佢唔好咁易 出入灣 Inner Wheel Spin 失去動力. 有 gear diff oil, 當inner wheel 離地時, outer wheel 唔會冇晒力, 仲有力出灣.

以上只是本人對真車既智識放係 RC到. 有錯唔好插. 大家討論下

The denser then diff oil is, the more harder for the car to lose the torque to one unloaded wheel.

Spool tends to understeer a little bit, let driver has more time to control the car, but eats tire a lot.
But spool has more direct feeling.
That's what i feel

gear diff唔同LSD, 其實有D 1:8 車車真係有LSD

C Hing,

Can I know what is difference between gear diff & LSD?
Thanks All !!

LSD is similar to normal diff, except it will "limit the slip" for the wheel with less traction so that will help the car to go for high speed corners typically

有錯物插

LSD for 1/8 and 1/5 have friction plates inside.  The rest is like a normal diff.  Under low or no load the diff will turn smoothly.  But when you apply throttle or brake the diff inside housing push apart and putting pressure onto the plates.  Causing the diff have "locking" effect.  Same as real car LSD.  Kyosho have similar design for v-one and 1/8 buggy too.  But instead for friction plate it use a square block to lock the diff gear.  

yes. Sure Gear Diff is not LSD. But it can help limit the slip a little

The gear diff of EP RC, in real car, they called it "OPEN DIFF". Nothing to do with LSD.

LSD is another story like jf813 c-hing said, it lock and close the diff with several different methods. At different situation. So there is 1 way, 1.5 way and 2 way LSD. Do NOT ask me what is this, you should know how to get this knowledge from Internet with tons of LSD information.

Basic overview of LSD:

http://en.wikipedia.org/wiki/Limited_slip_differential

Well. It is an open diff for sure. But why people use different density diff oil? What is their main effect on the EP? People use like 500K oil in the diff.... which is really hard to turn the diff.
