im VERY happy with my locked diff ... i pdripped wax from a Bday candle into the larger gear with the smaller blue gears in it.... accel is GREAT top speed is FAST as all... plus it helped my right turns ..... its so fast its hard to keep straight

man i got to get me some money so i can go out and buy me a few extra diffs and mod mine for drag sharp turns and sweep turns (but im a little confused on how to do this i no where to put the stuff im going with silly putty (my fav stuff) but what will it do for me cause i only got the rear diff for now)  oh yeah also i cant run my car (read civic on fire and that will explain)

A Limited-Slip Differential, also known as an LSD allows more torque to be put to the ground. With your stock differential if it senses that one side is losing traction it will try to correct it, do this, get your car in the air and accelerate, put your finger on one tire stopping it, the other tire will keep spinning and the one you stopped is just there, with no effort to move. On the other hand with an LSD both wheels will spin no matter what the conditions are, if you hold one wheel with an LSD both wheels will stop and try to keep moving forward. If I am wrong, please feel free to correct me.

Open /gear differential means that the power is transferred to ONE wheel. The wheels will spin in opposite directions when you spin one.
This HELPS in turning because as you turn, one wheel will go faster than the other, because the width of the car makes the wheels move in two diffrent radii.
Locked means that you no longer have any differential action at all. Turn one wheel and the other will spin with it, and the motor will too.
Power will be transferred to both wheels at all times. Therefore there is no slip, and one wheel will loose tractoin and make the rear end slide in a turn. In a real car it would make it hell to drive, and would wear out the axle, unless you don't turn, like drag racing. In a RC car with good acceleration and light weight, it makes the rear end slide out and skid around easy.
Limited slip means that you have some differential action, but the wheels will spin in the same direction when you turn one. sometimes only one wheel will spin and turn the motor, sometimes (depending on how tight it is) it will act like a fully locked diff.
With this set up (the ball diff) you get the benefits fo both. More torque is transferred to each wheel, but in turns, you still get power to both sides, even tho the wheels are turning at diffrent speeds. You also get the added benefit of slippage. This acts like a clutch, so that the motor's RPM's go up and stay up while the wheels take a while to catch up with the rest of the drivetrain. This causes a little lag in take off, but a much more powerfull launch.
Hopefully that's not too technical, but it is correct.
Which set up you want to use is up to how you drive, and obviously what you get to work.

and LSD isnt a locked differential. a locked differental has absolutely no slip or movement.

Lemme take a shot at explaining LSDs a little more indepth.
When you make a turn the wheel on the outside of the turn needs to turn faster then the inside wheel. An LSD wants to keep both wheels rotating at the same speed. There's a certain amount of friction inside the LSD that needs to be overcome to turn them at different speeds. The friction of the inside tire not wanting to slip transfers enough power inside the LSD to over come the LSDs resistance. The differential slips (ie the two wheels turn at different rates). This is good. You keep the car under control.
When you accelerate in a straight line one wheel is going to loose traction first. When it does you're dealing with a small friction difference between the two tires. This only transfers a little bit of force inside the LSD. The resistance inside the LSD to allow the wheels rotating a different speeds is stronger then this force. The wheels turn together. You get more traction. Everything is good.
The problem comes somewhere in between a turn and staight line acceleration. Say accelerating out of a turn. When you're coming out of a turn the outside wheel has more weight on it, so it has more traction. When you go to accelerate there's a bigger difference in friction between the wheels then if you where accelerating in a straight line. The resistance of the LSD to slip needs to be greater then this difference to keep the inside wheel from spinning and sending you into a bad oversteer condition. At the same time it needs to be less then the difference during a normal turn or the inside wheel will spin and you'll oversteer going into the turn.

If yuo are realy set on locing the diffs use JB weld. Note this is not reversable

Obviously if it says LIMITED SLIP, that means there is some slipping involved, locked means its locked, doesnt move at all.

ok i was driving my civic when i noticed it was studering and pulling to the right some i adjusted my trim but it still goes right i switched out the tie rod with another stock one and it still pulls and it still studders could something be messed up with my lsd cause i no its not the electronics (itss a BRAND NEW chasie)

that is so wrong...BOTH diffs are independent of each other...locking one will NOT lock both....unless you have a magic x mod...dont believe me...lock the rear one and grab the left or right front tire....spin it...and see the other tire go backwards...
