Make your AWD XMOD haul ace!!

Hey, I just found out that if you have AWD and switch the front and rear differentials. Have the ball diff. in front, and the LS in back...then for some reason it goes super fast. I raced my friend who has the same upgrades as i do and it isn't even a contest...i just own him in every aspect!! I definetley recommend doing it

hmmmm.....ill have to try that next time i change the springs......or when ever the next time that i go "under the hood" is........but im still really happy with the AWD. as it is......i wish there was somone around here i know that has an xmod......i need to race..........

Man, I know how you feel. The only r/c's around here are either zip zaps or microsizers. I guess you could race a ZZ and an XMOD but that wouldn't be very fair.

Just do what i did tell all your friends that you think might be somewhat interested in RC to go buy a Xmod and you'll all start racing together.I told 3 of my friends to go buy some Xmod's and i let Anthony use my black civic for a little bit and he seriousely wanted to buy one after that and then i told him about all the upgrades and stuff and he just got hooked.....man i should work at RS

Last time we wen't rollerblading around town i stuck my Xmod in the starterkit case and rtook it all over town takin it out at every spot we hit

So just spread the word.

Yea...trust me this really helps your acceleration and cornering...don't ask me why, it just does. Give it a try...it can't hurt

i'll try to explain. lets assume that the tires have perfect traction so there's no wheelspin. with the regular diff (gear type) power is instantly transfered to the wheels thus accelerating away with full power. the ball diff on the other hand, kind of acts as a slipper clutch. if you've looked inside the ball diff (i can post pics of both ball diff and gear diff both taken apart if requested) two metal rings connected to the driveshafts press against 5 ball bearings in the middle. metal to metal isn't the best material for surfaces that need to grip. thus, when full throttle is applied, the ball bearings, which are carried in the middle on the main housing, will be overcome with too much torque and slip on the two metal rings. with the tires fictional perfect traction, no power is transferred. higher quality ball diffs will allow some adjustability to loosen and tighten it. this will make turning easier/harder and tightening it will give the ball bearings a higher threshold before it slips.

basically, the xmod ball diff will limit the two wheels connected to it from spinning at too different of a speed making it harder to turn. it tries to turn both wheels at the same speed so that if one wheel loses traction, the other still has power to keep it moving.

this is opposite of the gear diff where it's great at turning but when one wheel slips, power is lost to the spinning wheel

So it will act more like a 1 or 1.5 way limitted slip?

TypeZer0 · #9 12-09-2003, 09:26 AM

it acts as both a 1.5 way lsd and a clutch. ever redline a car and drop the clutch and the clutch can't handle it and the car doesnt' really move but you smell a burning? same thign with these except they don't burn, they're not tight enough to handle teh full throttle of even a stock xmod
