RCRacer- if the 10L2 you are running does not have an oval chassis on it which i dont think it does you should run the 10LSS..that SS kit was specific for oval and you can update as you wish to get it to the current configuration of the new cars..rollout can be figured out a couple different ways..i use the method of - pinion divided by spur multiplied by 3.14 multiplied by tire size...the final number you get will be your rollout.

Thanks for the suggestions,and formula. But I'm a little confused I thought that the end result of roll out gave you what pinion size should be. if that's incorrect then what's the reason for knowing the roll out. How is it usefull for tuning/speed or whatever????

it doesnt give you the pinion you are supposed to run but it gives you a formula that puts the tire size into the equation..when your tire size gets smaller your gear ratio also changes so the rollout formula allows you to stay on top of it alot more.

Hey Brian,

I recently purchased a 10L from a friend of mine and was wondering what needs to be done to it in preparation for the Snowbirds. It seems like it is a really good car. The main pan is made out of fiberglass and it appears to be a wide car. Right now I have a rooster speed controller in it along with a magnum sport radio and a Futaba Sport radio. I was wondering what T-plate will work on this car along with front springs. The car only has 1 shock on it along with it appears like friction discs. Any help will be appreciated.

Hey Brian your car was a rocket at the NATS this past weekend !!! Thought you had it in the bag you'll get um next time !!!!! What compound tires did you run !!!!! SEE YA HACKSAW:devil:

yeah brian great run! fun watching the big dogs run mod. i think you had it go down to a tie breaker right? great run both you and sean were fast!

Hey Brian,

Can pinks and purples be used on flat carpet oval in 4cell 19turn?
For example 3 purples and a pink LF or 3 pinks and a purple RF.

Tom

GotDelivered- it sounds like it might cost quite a bit of money to get your car up to todays specs because the only thing you would really be able to use is the front end...if you do want to get it to todays standards i would recommend buying a used 10L3O and use your current car for the parts as you might need them..hate to to be the bearer of bad news but it will cost you much more to convert than it will to just buy a current car.

hacksaw- thanks alot...i had a good time this past weekend..racing with sean was alot of fun and i always seem to finish second in those triple a-mains but it was still a good weekend overall..i ran a black RF,pink LF,Gray RR,& pink LR.

katfish- thanks alot man..i appreciate it...congrats to you on your win in 4cell stock...hopefully that will be one many in the future for you.

TOME- i wouldnt recommend that tire choice because they hook the car up too good...if the track is sitting right on a concrete floor you can usually run them on left side to help the car but if it is sitting on wood you should stick with the black,gray,white family of tires.

Brian......Okay, here it goes i did my rollout with the formula you use. Now what I really want to know is this. What does going down in the rollout do, i had a 1.55 rollout with a 120 spur, so i did it with a 116 spur and got 1.61. So does going up on the rollout work better for speed or does going down in the rollout work better for speed??????

I run on a flat track, few bumps, 8-10 foot infield, 160 or so drive line.....

Thanks alot

Keith

rckfracing- the higher the number the rollout you have the more top speed the car will have...keep in mind you also lose the bottom end punch by running too much gear as well...go to a couple fast guys at your local track and ask them what they are running and see how close you are.

Yeah, also keep in mind that if your roll out/gearing gets too high, you may never reach that top speed.

Brian,lets get some talk about l.h.f.tires,Its hard to get it to wear more than r.f.lets do some talking,right now using a marshmellow onl.h.front & still using purple r.h.f.more.DOM-19 BTW ON ASPHALT.

Brian,
I'm pretty sure I saw a switch for a reciever pack on your birds car from last year. Are you still running one? Does it it help in 4-cell stock class? What type of pack are you running and what's it's weight?

Thanks Greg

Brain I have a question about 19T 4 cell What brushes and spring where using at the birds with your motor thanks

Keith, you want to have right around a 160 roll out at haverhill and also to answer the question you had about your car kicking coming off the turn there, you want to run a slightly harder tire on the right rear than the left rear. the reason for that is that the right rear tire is still trying to turn the car coming off the corner. so you need t omake it have a liitle less bit than the left rear. this is what i found at this particular track anyways. let me know if it helped. thanks jeff travis:thumbsup: :eek: :devil:

DOM- there are a couple ways to get your left front to work a bit more..the first thing is to run a slightly stiffer spring..i usually run one step harder on the left front than on the right front..another thing is to make your left front upper arm flat so it takes the camber gain away from the tire..when you push up on your left front the tire should stay flat instead of angling inward..this will keep the tire flatter going thru the corner.

metrodog- yes i was running a switch on my receiver pack at the snowbirds..i dont think it is necessary to run one in 4cell stock but if your car is light and you have to add weight you might want to run one...its not going to hurt you at all and may help just a bit.

red dragon- to be honest im not sure but if i had to guess i would say it was the Putnam Green EFB-170 brushes and green negative spring and a red positive spring...todd did my motors for that race and i just put them in the car.

Brian,

I took your advice and decided to upgrade to a new car. I spoke with a good friend of mine and he told me that the car to beat in 19t and mod at the Snowbirds was the Carpet Pro. Yesterday I went ahed and purchased a brand new one. I hope I have the same success that last years winner had.

Brian
what kind of set-up did you use at Akron for the nats springs,oils,axle positions,body,battery position? and about where did you roll-out? We have been running mod there and were getting close, i wanted to see how close we were to your setup and roll out and try some diffrent stuff. With 3300's we should be hiting 63's when the track comes around wouldnt you think?
thanks

So i could try a green rr and a white lf or something?? What kind of tires did you run when you ran there???

Keith I ran BSR's LF single blue
RF DOUBLE BLUE
LR WHITE
RR BLACK OR GREEN
NO STAGGER
SOFT CENTER SPRING
PURPLE FRONT SPRINGS
TRACKS FEELS LIKE THE CAR IS LOOSE BUT ITS ACTUALLY TIGHT AND THE N KICKS SO YOU THINK IT IS LOOSE, GET THE CAR REALLY FREE IN THE TURNS AND YOU WONT BELIEVE THE STRAIGHT AWAY SPEED YOU WILL HAVE, SHOULD ONLY HAV TO BLURP THROTTLE O GET THROUGHT THE TURNS, YOU WILL DEFINETLY HAVE TO LET OFF THOUGH, IF YOU DONT THEE CAR WONT TRANSFER THE WEIGHT AND TURN FOR YOU.TRY THESE THINGS AND LET ME KNOW.

i will try what you have gave me and i will let you know how it goes, i want 62 laaps bad!!!!

do you know if tj is going???

thanks alot Keith

Brian, What would be a good setup for 4cell 19turn and mod for a carpet pro with T-bar. Our track is 115 feet on ozite over concrete.

frank- ill do as best my memory allows me to. long wheelbase, spring steel tbar,offset pod with the tires pulled as close together as possible, red right rear side sping with 30wt oil, gold left rear side spring with 30wt,red HPI center spring(very stiff)50wt oil, batteries back on the 4cell tray(last cell under rear chassis brace halfway), completely stock associated front end, .020 RF spring, .022 left front spring,purple stuff on the kingpins, standard Protoform Monte Carlo,big wing mounted on body..im not sure of rollouts but i know i ran an 8 single with 4383 brushes setup at 12.5 amps at 2 volts.

JBRACER- back in the posts somewhere is the setup i ran at the snowbirds...i would start with that but maybe soften the front springs one step being that the track is pretty short.

Brian do you remember what you ran for tires at Classic? thanks LBJ!!

Brain recently I have not been making run time. I have made gearing changes chassis changes ect. Nothing seems to help.When you have car that is not finishing strong what do you look at first. I have fresh 3300 and new motors we are running 10th mod. Any suggestions would be helpful!!!! thanks LBJ

Brian, I saw your post on the carpet pro setup. With the new grey compund where would you run it LF and RR? Our track doesnt seem to have enough bite to run a black on the rear. I have been running Green LF Black RF White LR Aqua RR. Thanks for the help.

larry- when your car isnt finishing 99% of the time its because your car isnt efficient enough...at classic my car got alot more efficient when i stiffened the center shock spring...i ran a black RR,white LR,blue RF,black LF.

JBRACER- yeah i would try the gray on the LF and on the RR for starters.

Thanks Brian

Larry- you coming this weekend i think you might be running too soft r-front tire?

Hey Brian did you run offset pod at BIGDADDYS ? I'm thinking about trying it on my 19t car !!!! What side shock springs should I use ? SEE YA HACKSAW:devil:

Thanks Brian I am soft in the middle. Frank I will be there this week end. I'm going this week also to get some 4 min runs in. See ya at the track. LBJ

hacksaw- yes i did run the offset pod at big daddys..helped the car alot coming off the corner.

Brian, What factors do you use to decide to run offset or standard pod? Is the offset pod better for flat tracks or ovals like Sandhills? I usely run stock.

Also on the IRS frount end with the inside and outside holes how do you decide What side to lengthen and why.

I know a may be asking alot, just trying to get a handle on somethings.

Thanks in advance for any help you may offer. :confused:

LarryB- i always start out with a straight up pod and go from there...if traction is not very good and im having a problem getting off the corner then i switch to the offset pod..the offset pod will give you more traction coming off but wont affect the car going in...the longer the front arm the less camber gain you get but it also makes the spring slightly softer...the car is a touch less aggressive with a longer right front but helps the car the get off the corner a bit better..when you run a shorter right front upper arm the car is more aggressive everywhere...i usually dont mess wth the length of the left front arm...why you would change any of it really depends on driving style more than anything.

Brian, What day are you going to the race next week? Don't forget to bring the duct tape.




Ziggy

Ziggy- ill be there tuesday...i have so much duct tape you cant even imagine...dont want to lose any shoes in the woods.

Brian, Tommy and I are going on Saturday to race the club race. I will not be gettin there untill wednesday morning when the track opens for practice. I am sure Tommy and I will call you sometime this weekend.



Ziggy

I got a problem with my car rolling over ing the turn
tryed a number of things all bad turnouts
whats your idea
very short track two drag strips with hairpins

Hi Brian, I'm fairly new to the oval racing and I've checked out all the different cars and I decided on the Mac Attack Carpet Pro but I don't know to buy one as our local hobby shop can't get one. I live in NJ and race thru out the Tri State area.
Any help with this will be greatly appreciated. I look forward to seeing you again at the Birds in February!!!

Brian, I have been running a flat track about 120' race line. This past week I TQ'ed the stock class and had the fastes car in the qualifiers. In the main the car got what I call a push lose condition. What may have caused this? Should I have changed the tires due to tire tack build-up? I ran Jacos, lf-black, rf-purple, lr-white, rr- pink. Or should I try different compounds.:)

Larry B. - I'd get rid of the pink RR and go to a black.

Hey Brian any chance of you coming to the Winterblast at K & N Jan 17-19 ? We need to get some of the top oval racers back up there.

Mark Z

DVL- when you say rolling over, do you mean traction rolling or just leaning very badly..let me know which one it is and ill give you some suggestions.

Larry- hope what i spoke with you about helps you out.

raymann- my best suggestion is to find a couple tracks that race and sell oval and give them a call..location shouldnt really matter because they can just ship it to you.

THE BAT- i really doubt i will be there being that the snowbirds are so close to that date..things could change but id hate to commit and not be able to make it.

scrubbing off speed is what my car is doing right now in the corners. the car is totally glued to the track otherwise.but going in to the corners you can hear it biting into the concrete slowing the car down,,they are telling me to free the car up.we are running 4 cell stock on a tri-oval..i have a g-force with dampner tube..ok ok ..so it might be my driving ..lol but what might help this?... heavier oil in the center shock? stiffer springs in the front?>>..tires i use
r-front.green..L
L-frt..red L
L-rear red..L
r..rear..green..r
basically the car is all stock with the exception of the left frt. alum. caster block in the top hole

Hey Brian,

How do you make a chassis more efficient?

Tom

Brian:
This past weekend I was running at a local track that is an asphalt oval with 15-20* of banking and a driving line of about 260'.

I was having a real bad handling problem. I could keep my 4-cell mod car pinned in the corners. I was running a very fast 9 and hd just as much rip as anyone else, but on that track you should not be able to keep the car wide open during the corners. If I did let off the car would spin out of control. My other problem was that I could not make 2 ½ minutes out of the car. I was plagued but this all night and could not shake it. It just never felt right to not drive the car pinned. It was a weird feeling.

I came up with the conclusion that the car was very loose and the only way to keep it going in the corners was to keep it pinned but that was killing my batteries. Could this be possible? The batteries ran fine the week before in mod but this last race it just an odd experience. If you have any incite as to what might have caused this I would be very happy. Thanks.

I have looked at many of your set up sheets and i have found that you use 2 diffrent traction compounds, what are they and which one does what? I am currently running on a banked track and i see that you have posted before it would be faster to run blacks or white ect. now i am running 3 greens and a blue what compound should i try.
Thanks
Matt Erich

BB,
Are there any rules that prohibit lightening of armatures? If so what classes?
Thanks Greg

Bummer maybe the SPRING SIZZLER ...:D :wave:

PITBULL- the first thing i would do is put the associated side shocks on your car..this will alow you to control spring rate which you cant do at all witht the tube and also control the damping rate by changing oils...if you cant get the shocks right away i would run a bit heavier lube in your tube like a trinity red stuff or maybe even purple stuff...you also might want to try to go to heavier front spring to get the nose of the car released from the track a bit...if it sounds liek its really biting hard going in its definetely killing your efficiency and your corner speed.

TOME- well that is a difficult question to answer without rewriting the bible...there are many different factors that make a car more efficient...different tracks all require different adjustments...its very difficult to tell what to do until you actually race there and see which area of the car is hurting the most...for instance in akron we couldnt get the cars to finish very well because we thought the cars were too loose off the corners which was a contributing factor but the thing that made the most difference was stiffening the center shock spring ALOT..this got the car up on top of the track and gave us the additional runtime needed to go fast and to finish...when i was in atlanta a couple weeks ago we had the same issue with the car being loose coming off but i actually had to bolt the back of the car down by running a bit softer tire and this made the car more efficinet because of less wheelspin...so there are two examples of the same problem at two different tracks and two completely different solutions that are very opposite of each other.

JPH- usually when you have a car that is so loose that if you get off the throttle it will spin out there is no way you will ever make runtime..2 1/2 minutes is pretty extreme but not impossible....you might have something bent or broke in the car and you dont even realize it..i would take the car apart and completely rebuild it inspectin each component as go along..if anything needs to be replaced do so then put a very basic setup on the car that you think will at least get you close and make sure the setup you use keeps the car very drivable...from there you can analyze what is needed to get the car more up to speed.

merich- im not really sure where it was about the different traction compunds but anywhere i can i always use paragon ground effects for carpet..i usually use trinity tire tweak outside on asphalt but thats two different surfaces...paragon seems to be the best and most consisitent compound you can run..as far as the tires i would definetly try the black,gray,white family of tires..on carpet they are much faster than the blues and greens.

metro- in ROAR it is very illegal and also very easy to spot...in NORRCA it is not illegal yet but from what ive heard it will be very soon.

Where would i but the compounds at, like black all the way around or where would be a good starting point?
Thanks for the help
Matt
