Default How to cure push?

I've been running dirt/clay oval with my Hyper 7 PCR. The problem I'm having is severe front end push. Anything that I do doesn't seem to make a difference. For diff oils I'm running, front 5000, center 3000 and rear 3000. I was running 7000 in the center and made the change to 3000 and it didn't seem to make a difference. The PCR has the 6 spider gear SPYDER diff in the center. I've been running a brand new set of ProLine Crimefighter XTR's. Anyone have any clues? Thanks

Im not sure if this will help but in teaching my son to run his 8B and slash, I would make set up changes and he wouldnt notice what i did, but he would still tel me the car wouldnt turn, The best advice i could give him and some others at the track was to stay off throttle just a tad longer when in the turn til the car was between 1/2 and 3/4 into it, then get back on the gas, this seems to help so far...

I've been wanting to ask this for a while and this seems a good place to ask... What exactly is the term 'push' describing? I'm sure I'd find that I have tons of it if I knew what it was...

it's basicly when you lets say are intering a left turn and your turning your wheels to the left and the car wants to keep going straight, gettin off power when turning help a great deal with this...as it help to keep the front end planted...

I've been racing and bashing RC's for close to 25 years now so the driving isn't the issue. I can get the car around the track in the preferred line, just not at the "preferred speed". My friend is running the OFNA Picco buggy and he's getting around the track pretty good. I'm not sure if it's a shock, diff oil, sway bar issue. Maybe even a geometry issue?

Ok.. so like driving a real car on ice and trying to turn.

Is breaking the rear end loose also known as push?

Default try this

If the car is pushing through the corner then you need to move the shocks to the out side on the arm in the rear and the inside of the arm in the front. what shock oils are you running?

So you think the rear is sorta acting like a Posi with the 3000? Makes sense.

I ran oval about 10 years ago lol and i ran a hyper 7 pbs and i ran alot different set up than what you got i believe i ran 10,10,1 and i had my shocks set so when i enter the turn the weight shift to the front tires make your right rear shock stiffer and your left front softer so when you enter the turn most of the weight is still on the front that will help with the sterring and just blip your throttle to get around it. hope this helps

I'm not quite sure on the shock oil. I haven't changed it since I've gotten the buggy, it most likely needs it. What would you recommend?

Found the problem ^^^^^

Can you post a pic of your track? Track conditions? Bumpy, dusty, etc.

Can you describe as much of your current setup as possible? Pushing on entry or exit, on power or off. Diffs are only the beginning, and do more for on power than off. You should have a good off power setup diff wise allready. 5/3/3 is close to one of my favorites-5/4/3, and 5/5/5.


I'd try AKA soft I-beams for a messy outdoor track, Gridirons soft for a clean outdoor track. Go to hard compounds for hot blugroove.

Increase rear camber: -3 or -4 degrees on the right. Its an oval, you can use positive camber on the left if you want.

Can you shorten the wheelbase on that car? Move rear hubs, arms forward.
