TC4 Oval

NUCRPTRACER · 02-14-2007, 11:00 AM

What # should I be looking for on my roll out on a short track? I am using 64pitch,19T money motor....right now 100 spur and 35p....track is only 110' maybe...any suggestions? Also does anyone have a good starting setup as far as: spring color,ride height,toe in toe out, 4degree blocks or not,shock oil etc. would apperciate any help just starting out

depending on your motor im running pirelli rubber tires with a 66/36 gear on a 19t, gold springs up front, yellow out back, 40wt, 2 hole pistons, ride height set to the height of spur gear under each corner of the chassis, 0 deg rear toe, 1 deg front toe, 1.5-2 deg neg camber on left side, 1.5-2 deg pos camber left side, you have to lock the front end and have the rear diff very smooth. im running a short flat concrete track, never measured it but id say its pretty close to 110 ft around

Thanks for the info......but by locking the front diff do you mean just run it down and back off a little? I am running on carpet w/foams with a 19t checkpoint....66/36 is what your running....does your motor get hot? should I be able to spin the rear tires freely or is that to smooth or should I set it like the instructions in the manual? I apologize for all the questions....but for some reason I just cant get it dialed in,I am only getting about 74 to 76 laps and 3.6 to 3.9 lap times w/ traffic..but I ended up 5 laps down last weekend with one bobble and that was with the guy who put the 5 on me....anyway and if you could tell me what you have to multiple or divide by to get roll out I would appreciate it.

motor is around 140 after a 5 min race, and i mean get front spool, no diff, not a one way make it a solid axle, they are on back order from associated, i have decent used one you can have for 12 shipped. rear tires should be nice and smooth while holding the spur gear and turning the back wheels. a smooth rear diff is essential. how many laps is a good fast car running in 5 mins on your track, just as a comparasin we are running fast avg is 65 record is 67 for a 4 cell 19t car. may want to lower the car a bit further than i have due to running on carpet you have more bite than our track.

I have a spool diff and will give it a try....the fastest our track has seen is 94 laps and I fell victim to this guy he was fast....He ran L.T.O chassis(TC3) 19t komodo he was flawless to say the least....I have my rear diff spinning realatively smooth I just dont want to back off to far....by the way we run 6cell....I see you run NASTRUCK dont those look cool running oval I havent bought any touring bodies since I first saw a guy rollin the silverado body. you say your track is about the same size and you guys are turnin 65 laps....I must be wrong about the length of my track but I am almost positive. That gear ratio seems extremly agressive what kind of lap times are you turnin? Why the spool diff any particular reason?

loopedout · 02-15-2007, 10:54 PM

just turns better with a spool on small tracks. the owner told me tonight it was a 120ft track. fasted lap period on our track is a 3.8 second by a latemodel 6 cell 3.5 brushless car. carpet is faster, if youre track is 10-20 ft shorter and with the high grip that could expain. a really fast lap time for me is a 4.3 with the 4 cell limited brushless and a 4.5-6 with a 4 cell 19t. No one here runs an lto chassis, i have a fac team tc4 im building with an extreme lto chassis, should be killer

NUCRPTRACER · 02-16-2007, 12:16 PM

yeah I have a FTtc4 and I also ordered the extreme silver LTO looks wicked and I cant wait to get and put it together....I am going to put the spool in for this sunday(thats when my track runs oval) and hopefully w/the changes Ill be able to put up some good numbers....The problem I have is the track doesnt get a huge turn out...mostly T-Spec (trinity 1/10th if you werent familiar) so the owner just chucks all of us into a mod class regaurdless of motor so I have to race against some brushless guys which isnt to bad cause the closer I get to dialing in my car the more nervous I make them cause they dont want to lose to my 19turn, which makes them push a little to hard most of the time and that opens a window of opportunity for me.....I am thinking of trying out one of those Orion 3800 lipos this weekend to see what difference that makes and to see how it stacks up against my 4200's...Have you tried any lipos? Oh that gear ratio that was 64pitch you were talking about right the 66/36 if so thats gotta be one small spur! This site is pretty awesome seems how we have are own little thread....I am glad you answered doesnt seem like to many people are interested. sorry so long

loopedout · 02-16-2007, 07:55 PM

No problem. Im running 48p in that car. We can't run lipos at our track, the 4200's im running are wicked, too much battery really. Power isn't an issue at our track, rather harnessing useable hp is the key. Ive trimmed the throttle epa back on my sprinter with a 5800 brushless, its just too much, I cant put the power down. Ive got pan car rear foams and using alot of dope to get it to stick, I go into the turn with the sprint the car gets a little sideways and you can hear it kind of skipping lol and im shaking the tires down the straight. Good luck at the track, I know I always need it

NUCRPTRACER · 02-19-2007, 03:44 PM

Man that spool worked out.....I came in third though had some other issues...I was barrell rolling in the corners, but thats easy to fix just need a little more tweaking....I think I was just pushing a little to hard in the corners...My lap times picked up considerably though.....I am going to try to get it really hooked before I change to the LTO....do you think thats a good Idea?

loopedout · 02-19-2007, 04:27 PM

it cant hurt running an lto, no one at my track does though, although they do try to offset the car as much as possible and get the weight to the left side. I did outstanding this weekend myself, i had the main in the bad had i grabbed the right battery, some how i grabbed one of my practice packs that i had already used and yeah, 23 seconds left in the main almost 1/2 track lead, the battery dumps. I couldnt believe it.

NUCRPTRACER · 02-19-2007, 06:30 PM

unfortunately I have been there myself.....u ever stand there looking at your packs and go is it this one or this one? now i have tagged them w/ a loop of tape white for race and black for practice...i use the white to write on...u know to jot down which one i should use for main....well i think i will go ahead and switch over to the lto just dont know if i can get it done by this weekend.... I did buy a 10L3 of ebay and i am going to try to get that ready for this weekend also...got any tips?

loopedout · 02-19-2007, 06:41 PM

i havent ran pan cars in almost 15 years lol. i have a system for keeping track of my batteries but just overlooked it, wont do that again... for awhile anyway

if you have the xtreme chassis it'll take two evenings to get it together and then setting it up may take a few packs, get it together! let me know how you do with it, hopefully youll dust everyone. im going to see if i can get my sprinter to handle with the 3.5 motor. that should be interesting

NUCRPTRACER · 02-21-2007, 01:28 PM

Hows that tc4 comin along? Let me know if you figure out how to get the toe out of the rearend....Are you going to use any of the arm shims on the LTO?...Maybe I can learn from any mistakes you may make before I get mine together(hehe) Did you get the silver carbon or the black? Speaking of chassis have you seen the chassis from diggity if not lookem up on the net it is pretty sick lookin its not lto but man its sharp! Do have aluminum knuckles and carriers and arms if so where did you get them? My pan car arrived today looks like fun now ive got to get the electronics on it and get some 4 cell matched packs so I can run it on sunday...cant wait

loopedout · 02-21-2007, 06:22 PM

well im busy with the sprinter right now, the new tc4 hasnt hit the track yet. were still doing quite well with the tc3. and no i dont have any alum suspension parts on it, just the associated stuff. ill pm you the trick to the rear toe fix, top secret stuff ya know lol. i did a bit of 1/10 pan cars a long time ago on a big oval, its was actually a bicycle velodrome. the old rc500's were insane fast. then I ran some 1/12 on road modified, those cars are crazy but a ton of fun. You will really enjoy the pan car once you get it set up, they are very fast and handle, well can handle very well.

NUCRPTRACER · 02-22-2007, 12:30 PM

Hey im still waiting on that top seceret info from the loop classified files.(: Hey should I take the shims out from under the arms so I have the lowest possible roll center or what u think? I got all my electronics for the pan car hopefully I will get it done shouldnt take long batteries will take longer I think plus I dont know if I allready asked or not but do you shorten your wheelbase and do you run positive caster or negative? I know positive would reduce your exit steering which could be helpfull I would think...i dont know...that always gets me into trouble thinkin that is.....Are the 4degree caster blocks you can buy are they +or-? I bet your getting sick of my questions...Anyway all your help is appreciated and good luck on the sprinter....this is your mission if you choose to take it and this message will self destruct in five seconds:::::::::::* sorry I got wrapped up in the top seceret talk
