Default ntc3+

hey guys, i have a ntc3+ that has really really loose in the rear on turns. tha back of the car will just spin out. i have changed the shock oil to 60 in the front and installed new 40 in the rear. and that problem was with rubber tires(cs27's). last weekend there were no box stock nitros at ourclub race so i put on trc's double purple's on the front and tan's on the rear. the car was still really loose. any ideas? thanks.

if you look around the fourm there are guys solving this problem from awhile back by adding -2 toe i think it was and 40w shock oil correct me if im wrong.

Thanks Rookie,
Took the shim from behind the collet and it almost fits. Will have to work on the shimming tomorrow. Problem is I cannot get the pinions off the bell. It will take some effort. If this gets to be too much of a hastle, I will just sell the clutch. I really did like the k factory 3 shoe clutch, but broke a spring. I cannot spend too much time with this, because I now have an RRR too and I am trying to get used to it. Without a clock, I feel more consistant with the tc3 and I have it hooked,, but when I get it right, I feel I set quicker laps wuth the RRR. I should know SUnday at the trophy race. I will run both during practice and then decide.

Or anyway I can fix my problem?

I have set my clutch spring collet to the far outside area...that is = engage sooner and smoother with the LEAST punch, I cannot not lossen it up more.....if I turn in the collet more, engage later with higher RPM, I am afraid that will only get worst....

Heavier fly wieghts may help your problem as well. I would make the end play on your clutch bell smaller first. Say if it is 0.7mm now, try 0.4mm this will make it engage a little softer. Good luck

I think the NTC3+ comes standard with that problem!

I had the same thing with mine, I added -2 degrees toe on the rear and set the ride heights so the front was slightly higher than the rear. Along with correct tyre choice, the car now rockets out of the turns (Thanks to AndyT )

Where you using electric sedan foams? That might be one of your problems. I usually use Ellegi 42/40 shore sometimes Ellegi 42/42 shore.

my car did the identical thing, and all i changed was the camber on the rear, leave the toe in and reduce the camber, or stand the wheels straighter up by a degree it worked for me, but at the same time I also changed tyres, this was on rubbers btw

Trust me, if I do have the time like you, I will get the RRR or back to 710 and call it DONE with NTC3.......I garantee you that the RRR will be a better car now over the 4 years old NTC3....however, you just cannot beat the simple and clean layout of the NTC3 and you can replace almost anything within 5-10 minutes....I bet the different with RRR and 710.

Let me make sure 1 thing...you add those little shim on the 1st SPUR gear, no shim need to be added on any PINION gear....I am not sure why you have to remove the pinion off the clutch housing.

End play is 0.5mm now...I don't think and see if I go any lower then 0.5mm will soften up by a lot.
Heavier fly weighs will required higher RPM to engage (just like dialed the springs more).......that will only get worst.

May be a softer springs and a ligher (drilled) fly weighs will answer the question, but again, that is a lot of work and times, I am back to the MIP clutch and 2 shoes and will see whats the outcome....thanks guys.

Other than setting it lighter thru less spring tension (going by your post it looks like you already have it set as soft as possible?), you could possibly try a lighter spring to give you more leeway to have it engage earlier in the RPM.
yes...I cannot loosen up that nut any further....or it will bind with the housing and did a complete lock up........but your softer spriing idea is a good one, I will see where I can get one....Mugen parts are not easy to get here.
Thanks..........

I was using kyosho 35v rubber tyres on kyosho inserts, thise tyres are now screwed (4 sets of) and the plan is to get some sorex 36r with hpi blue insert, because I hear around the traps that they are better

I just picked up some shims, didn't have any that would fit. I already put back the 3 shoe ckutch for tomorrow. Maybe I will try again tomorrow night.
I picked up an mtx3 2 months ago, liked it but my lhs now stocks the RRR so I picked up the WC, and sold the mtx3. Reason I sold the mugen instead of the tc3 is as you said, so easy to work on, and for dirty tracks, I do not have to worry about belts, Just damn one-ways Plus, I got alot more back for the mtx than I could with the tc3. The other thing is I am still very competitave with tc3
