ntc3 spinning while braking

My ntc3 always spins fast under braking, always 180 degrees. It started
happining about a month ago and I've exhausted all means as to figuring out
what is causing it. I've never had a car that has done this, my brother's
ntc3 is fine, even under heavy braking with all wheels locked up. My
neighbor's hpi is fine too. Here is what I've done so far:

* Checked alignment: Tried 0, 1, and 2 degree toe for the rear
* tried 0, 1, 2 degrees toe in and out for the front in different
combinations
* tried different camber angles,
* replace all the bearings,
* cleaned out diff and put back together
* different levels of tightening on the diffs
* new wheels and tires, different combinations of wheels and tires,
* checked for play in suspension,
* rebuilt cvds

After all this the car will still quickly pull a 180 to the right, and
sometimes to the left. Any suggestions?

Re: ntc3 spinning while braking

Borrow an MIP Tweak Station and see if your spring preload is all equal.
You might have uneven pressure on one of the tires. The other thing to look
at is binding in the diffs and axles (bearings).

Re: ntc3 spinning while braking

What kind of tires are you using? Foam or Rubber?

I use Foam Tires on my NTC3. My Rear has 3 degree toe-in. Suspension spring
is stock, Shock oil weight is 40wt all around.

I give like 6 mm droop for my rear end. Front is 5mm.

If you find my setup still bad, then I would suggest that you REBUILD the
car from Step 1 of your Instruction manual. That's what I did to my Serpent
Impulse and finally found that the arms are bent. *duh!*

By the way, do you have a One-Way or Solid Axle somewhere in your NTC3?

Try moving your left shocks to the right side, and the right shocks to the
left side. See if it changes the direction that it spins. If so, check your
shock oil and shock pistons to make sure they are all the same, or the same
on each side.

Make sure rear diff is not looser than front diff (and slipping).
Try dialing out the brakes a little bit do they dont *completely* lock when
you hit them (you may have already done this).

Let us know what fixes it just in case someone else has the same problem...

Thanks

Re: ntc3 spinning while braking

I haven't gone to step 1 but I have redone the whole drivetrain and
suspension. I also still have the standard ball diffs and arms are perfect
with no excess play.

Re: ntc3 spinning while braking

I'm still working on it. I'm getting the diff rebuild kits to change out
the bearings and friction disks for the front and rear diffs. I tried the
brake thing but it leaves me with long brake distances. I will let the
board know when I fix this. Thanks for the ideas though.

Re: ntc3 spinning while braking

I had this "180 Spin" when I was driving my Serpent as I have mentioned
earlier.

It has a something to do with the droop and suspension. There's nothing much
with the diff, because if your diffs are loosen out, it will only make your
car handle better and not much top speed. The pressure plates will be the
one suffering from the Diff balls causing all that friction.

Try to use a new set of tires (foam ones) and you should know the problems.

Re: ntc3 spinning while braking

I don't have my differential rebuild kit yet but I did notice that my
pressure plates are worn, (they have grooves from the carbide balls. I
flipped them the other way and tried running my car. It was better but
still spun under heavy breaking but performance was acceptable. When using
very soft tires the problems pretty much dissappeared from the added
traction. Thanks everyone for all your advice.

Re: ntc3 spinning while braking

I think that this can be caused by several things.

1) one of the wheel bearings is worn out. This has caused me to spin
out under power and not breaking, though.

2) the car will spin out if you have the front and rear tires
switched around (ie harder tires in the rear and softer tires in the
front). the same thing can be happening if you have the springs
reversed, also.
I have only seen racing done with harder springs and tires in the
front.
