Darnold...thanks for the info...at the last race Socko was talking about the rear tires...gray vs. pink and said the pinks scrub too much speed....since i didnt have any other tires i was stuck...i have a set of grays waiting for me though........i didnt notice the black stuff on my chassis cause its black also...but when i got home and saw that my batteries were nasty sticky.....i'll give your suggestions a try.....going to get a new car this summmer...prolly 12LS......i like having the option of 4 and 6 batt. slots.....:D

Dragon,

You can copy my setup, it should work the same on your car. Like I told Dave, I've got tons of steering and the rear end is hooked up too. I have to be careful sometimes in the early laps so I don't traction roll from turning in too hard.

Dave,

Sorry, haven't tried any P94s. I don't wish to go over to the "Dark Side". j/k How did you get the ride with Integy? Do they set you up with batts too or just motors?

Darnold........I'm using Paragon FX2 sauce.....i put it on approx.20-25 minutes before my heat and just wipe the surface before the race...i try to do the tires the same way everytime....so, hopefully it will be consistent....and i am running on Ozite......we have about 7 or so race weekends on it.....

Socko....i'll give it a try.....

Soko- Integy is just motors I run for SMC on the Battery front and their batteries are the best in my experience and opinion. Met Arthur & Pat at the Carpet Nats last year and we pitted next to each other along with RobK. They are really nice guys but it can be pretty difficult to get stuff. I have Arthur's cell # and I have found this mode of contacting him is better than e-mail. Their business has been so successful that they are constantly busy and hard to reach. The Ti motors magnets are really awesome and seem to last forever but the P 94's are even more efficient and the brushes last a lot longer. Also the power band seems to be a little higher in the Rev Range which necessitates a smaller pinion. Up until recently I used to think this was slower even though the smaller pinion gives a greater mechanical advantage that makes up for and actually gives increased bottom end on the track.

darnold,
I need some 1/12th scale advice. I have a few questions and maybe you could answer them. Thanks so much in advance.

I run a CRC Carpet Knife V3.1 with full aluminum screws, titanium turnbuckles and Lunford titanium kit for the Dynamic Strut front end. I have and Airtronics 94145 servo, Novak XXL FM receiver, Novak Atom, and ProMatch 3000HV with good numbers. I bought a Parma Speed 8. I currently run .020 springs up front and a copper shock spring with 35 weight oil and red side springs. The car comes with a red shock spring and white side springs but the car seemed lazy that way. I ran Jaco purple fronts and gray rears.

The last time I raced I was getting very little rear traction, it could have been that I did not goop my tires long enough or I had a cracked rim. Plus I switched to Losi medium Hydradrive in the dampner tubes, put on the stiffer copper shock spring and the stiffer red side springs. The previous weekend I ran 100 weight shock oil in the dampner tubes, red shock spring and white side springs and I had good rear traction but the car was lazy and slow through the corners. Both times I had good steering, so that is not a problem. I tried .022 springs up front and I did not have enough steering with that and .018 was too soft and too much steering and it was lazy. My local track is ozite with grip increasing towards the end of the day. The track dimensions are 80 x 35.

I bought a pair of TRC purple fronts and I am waiting for the local shop to get in the TRC gray rears. I would like to know if you prefer Jaco or TRC and why?

What tire diameter should I race with?

What should my ride height be in the front, middle and rear pod?

We are only allowed to use Racer's Choice TQ purple or orange at my track. I use the purple, how long before my heats should I apply the traction compound, when should I wipe it off and how much should I put on the front and rear?

I currently run a Fantom Green 3 with Putnam green (high silver) brushes. What should I gear it with a 100 tooth spur and what springs should I run on the motor?

Thanks so much again and your posts have been very helpful so far.

Hello Ty,

Try this, I used to run a Knife and this should work.

.022 front springs
Heavy Hydra on kingpins
4 deg. caster

Copper shock spring
70 wt. oil
Light Hydra in tubes
Red side springs

ride height 3mm in front, slightly higher in rear. Pod and chassis should be level at ride height, no "sag".

Make sure your side links are free. This can cause lots of weird handling problems if they stick. Try squeezing the cups with a pair of pliers a couple of times if they're tight. Loosen and reset your center pivot to make sure it's not bound up. When you have just the lower pod plate attached to the car (side and upper plates removed along with axle) The plate should rock from side to side easily and not "stick" or "click" to one side or the other.

With the shock attached the rear of the pod should only droop 1mm at the most. More than this will reduce front traction on throttle and make the car feel "lazy" entering corners since the chassis has to transition through the extra travel before it takes a set.

With TQ sauce put it on about 20 min before you run. Full rear and try 1/2 of the front to start. Wipe it off thoroughly right before you run. Adjust the amount of front dope to add or reduce steering.

Good tire sizes to start with are 1.8 front and 1.9 rear. Smaller front tires will give more steering if you need it but life is reduced of course.

Gearing is determined be rollout. With your track size I would try somewhere between 42 and 46mm. Stay on the low side since you run the Green 3 and want it to rev.

Hope this gets you started, I'm sure Dave will have some stuff to add that I missed too. Good luck!

What is a good starting piont for gearing 4 cell stock Trinity motor in a Trinity car?

Using 1.85"rears depending on the Trinity motor you are using is

GM3 26-100
P2k 27-100
P2k2 havent tried it yet.

Hope this helps if it doesnt look out for a great guy named darnold. hehehee

Darnold- I raced at Oktober fast and won the C main 1/12 stock. I was poor at the time and tried to qualify with only 2000's. As you can probably guess, it didn't work. So by the Main I had some 3000HV's and whipped my competition by seven laps. my lap times were faster than most of the B main guys! I got a cool plack though, and I got my body signed by Billy Easton and Barry Baker. I've been running mod ever since.

I have found some of your old mods here at the track... three Ti arms and Two cans. And guess what, I'm getting them all this weekend! woo hoo! I am going to expirement with fantom brushes, the 317's, if my track has some in stock. Well gotta go tweak the 12LC, thanks for the tips on the Carpet knife! come visit us and the rest of the Minnesota racers on Trinity techtalk! I got a 1/12th scale thread there too! hope I see you at the norrca's, I'm the little punk kid who will have an oompa loompa in the window of my 1/12th scale. don't think I'll run mod though!thanks for all your help and info!

thepetenis:batman:

Ty- everthing Soko said. Small clarification in case you didn't know, when Soko says 1mm droop here is a picture: when you connect the center shock the pod should move "backward" no more than 1mm so that it looks like it is trying to form an "A". What this does is it gives the car some extra front grip by not trying to "pick up" the front tires off the ground on acceleration and it helps to keep the front end from "washing out" going into a corner which creates "push". Also, this adjustment helps to stabilize the rear. Many people don't set their "knives" up with this. thanks Sako for giving TY the info.

petenis- Glad to hear it. LORD willing I should make it to the Norrca nats. Let me know how those motor run for you and how you do. I'll go over to the TT 12th thread and MN thread and say hi.-Dave

Went up to Grand Rapids yesterday. Boy the competition in 12th stock was awesome. Keith "Motor City" Hamilton, Rich Chang, Ron Ferguson and his to friends are really fast. Ron was in the Masters Stock "A" main at Cleveland. Rich TQ'ed and Won and Ron got third. I caused too much mayhem running mod with them in the first qualifier so I pulled out and ran inbetween rounds and had my laps & times counted. I was about .8sec/lap faster which is right on the bubble. I would like to have another .2sec/lap and since my 8 turn was lacking some punch people said even though it was still fast. The car was wonderfull on a track that had a black groove in it with traction similar to Cleveland/January Jam's races. It never wanted to traction roll and it had more corner speed than any other car I have run since coming back to this hobby (3yrs ago). All this AND it was easy to drive. Ron and many others really thought highly of the Trinity 02 edition car, now I just need some work! So how was everyones race weekends? Let's get some activity going. LOL -Dave

Pretty good..i used yours and Socko suggestions..picked up some new purple/gray's and went faster.....the grays seemed to go away toward the end of the run...didnt feel as planted as the pinks(loose)......did turn more laps though.....:D....qualified 2nd. finished 2nd.The leader and i ran 40-45 laps about 10-15 feet apart..nobody made a mistake, then, i hit a wall and 3 laps later the leader hit the wall in the same spot so we were right back to where we were...I finished 3 seconds behind....closest i've ever been to him.....lol

Thanks Dragon S. So what is the word out there with everyone else? I have to rebuild my diff. I had two of the new Boca Ceramic Bearings (flanged) and they both blew out in 1 wk each. I'm pretty disappointed and plan on e-m'ing them to let them know, maybe they will replace them with some regular bearings. I wouldn't recommend them right now though. So has anyone ever tried Integy Motors or Brushes and if so what did they think of them? I run for them and since Big Jim started doing their winding last summer their quality has really been good. I would honestly recommend them they use the Ti can and they are going to check into Possibly doing the P94 motors. Should see people out at the Indy race which is the 4th leg of the US Triple Crown Series and then at the 5th and final leg for the indoor carpet season which is the ROAR Carpet On-Road Nationals out in California, looking forward to both. Anyone else going to either of these?-Dave

Comeon we cant let the 1/12 thread to go to the second page!!!!!!!!!!!!!!!!!!!!!!!!!!K how about this.........Dave what happens if I use white rears instead of grays?????And which portion of the front tires do you juice????And finally in the interest of conversation does anyone use the FOAM DEATH GRIP traction compound or do we all use Paragon????
