Hey I have a losi 2.0 (with true setup except for 552 diff oils), and run on a fairly slick track with loose on the top. My rear end is just all over the place! up to jumps, line changes, out of corners. Its like its rear 2wd when I need 4wd, the rear breaks loose all the time. Any help would be greatly appreciated!

I tried
less rear camber
5k instead of 7 center
softer rear springs
raise front ride height
bald front tires to decrease streering

Thanks

go to 5k in the rear, yes it works(i know it sounds wrong). is the car less than a gallon old? then it needs to loosen up before it will feel better.

I would try:

try the 5/5/2 i use to run the 5/7/2

moving rear hubs all the way forward

run the +2mm in the rear only

soft clutch setup: black spring on composite and green spring on aluminum

dial in some negative expo into your throttle to soften the initial response of your throttle.

may sure nothing is bent in the rear (inner or outer hinge pins)

Have you tried a stiffer front sway bar, to help decrease front traction? Also you can try lengthening your wheelbase instead of shortening it. Shortening it will make it have better on throttle traction, and increases steering response, which is the opposite of what you are wanting.

Stiffer front sway, and longer wheelbase. Those are two simple things to try first.

+100000000000000000. Also make sure that there is sufficient throttle deadband.

I would avoid the bald front tires. They will make the car inconsistent.

a lot of times through the Speed Shop we see that either someone has built the shocks or it came from factory as roller and has some flashing on ths shock piston causing a lot of binding. It will feel fine on the buggy but without oil, spring, etc you will have a really bound up shock/shocks. This could cause a traction issue as well.

Thicker diff oil in the rear.

Man this seams to be the million dollar question. How to tame the rear. I have been trying for quite some time now.

Can some explain this negative expo thing.

stock settings accept for lowest amount of anti squat. truggy ring and pinion gears in the rear with 10 10 5 diff oils, max droop front and rear

tires? no matter what you change on setup tires are very important. also try reducing your epa on throttle to about half. make sure everything is clean and remove air filter and reduce epa until the barrell is only opening about half. you will have to lean it out after that, but that will just increase runtime. i did this 2 weeks ago at at loose track, and it was night and day difference. also remember to be smooth on the trigger.

Exponential is used to affect the response rate of the steering, throttle and/ or brake. Typically positive Exponential is used for steering, reducing steering sensitivity around neutral, making it easier to drive the car at high speeds in a straight line but exponential still allows for the maximum turning radius.

Go 5K or higher in the rear! sounds crazy! but it works!!!! it help's lock the rear in when under power! then you can adjust the setup, to get the steering and bump/jump handling.

cool thanks for the advice so far I will try these tips! my rear & center diffs are brand new (about a half gallon) if that means anything....but they are spinning pretty smooth at this point.

Since my rear breaks loose, and then spins like its getting all the power.....would thicker center maybe mellow things out forcing more power to the front?

A thicker center diff will transfer even more power to the rear under acceleration.

What radio do you have? Depending on which radio you have you will have to add positive or negative expo. I know a DX3R or S you add positive, my futaba 4pk I add negative expo. If you are not sure, with the car's engine off give your radio 100 positive expo and watch how the servo reacts to your finger input, then try 100 negative. One way will soften the response up to about 1/4 throttle. When you determine which way you need to go reduce the percentage to your liking.
