I race in northern IL. and Southern WI. was wondering what ever happen to 6-cell pan car racing? It would be cool to run brushless with 6-cell. It would also be alot easier to switch seasons with pan car, TC, dirt oval and you wouldn't have to buy so many packs. I would like to see someone start a pro brushless class using 6-cell and say sportsman class using the 4-cell. Does anyone have an opinion on this? Maybe some of these WI tracks would have an opinion or consider trying this, the speeds might go up some but back in the day we were about 10 laps faster in a 4 min race and had plenty of racers. Right now there is no local track in Nothern IL. to race carpet or outdoor 1/10 pan car.

4-Cell has surpassed the speed of 6cell at all of the tracks around here in Wisconsin. Most of the oval racing in the area is concentrated on the outdoor tracks in the summer, Midwest Triclone(West Bend WI), Storm Steel (Cedar Rapids IA) and Marshall town in Iowa are the busiest tracks in the area during the summer months and all run Cap tires. 4 Cell 13.5 Brushless is running as fast or faster this year than 6 Cell did before it died. The 4300 cars are about 3-4 tenths faster than the 13.5's if your car is setup properly.

If you want to go faster there is always BL modified. They are fast enough that very few can drive them WELL or afford to keep tires and parts under them.

Oval was dying a slow death at the end of the 6 cell days and at the moment it is growing again the way it currently is.

If you are really interested in more voltage there is a group of guys in various areas of the country getting lipo racing (7.4V) going. They are working on a class structure that would have them going no faster then we currently go though.

At least 2 things happened...
1, With the weight of a 6 cell's car and the gumball tires we run, tire bills were pretty high, the idea of a lighter/slower car was appealing to many.
2, It takes quite a bit of talent to wheel a faster car so 4 cells made for a tighter field (Made people feel like they had a shot) and thats also the main appeal to stock racing.

I see your point but most chassis come made for 6-cell and there is no information on most websites for me to look at to decide on a new chassis besides assoc. and I will never run one of those cars again. Also its very hard to work on a set-up or chassis and driving if you have no place to practice indoor or outdoor. If 13.5 is so much faster with 4-cell than how come no one lets off going into the corner? We had to let the car roll into the corner using 6-cell just like the big boys do on sunday.

Sorry if I left anyone out. You can go to this part of Hobbytalk and ask any question's you have of the above chassis.

Sure, 6 cells with todays motors would be faster then back in the day. But, there isn't a need from a speed standpoint. There are reason's to move back to 6 cells, but at this time it isn't a viable option. As soon as Novaks Brushless stock motor for oval comes out then it would be an option.

Personally, I think 4-cell is expensive enough....
If we went to 6-cell, I sure would be faster.
But so would the guys that eat my lunch now.... :drunk:

I don't know how it would get anymore expensive than it did in the old days. You don't have all the motors and equipment to go fast, and you're only talking adding $20 to what you spend now. What are we gonna do when Li-Po finally comes about thats 7.4. I just wanted to ask a question. All you guys started racing when they were running 6-cell back in the 1400 or 1700 NICD days i bet. Thats when I started and thats what hooked me into the sport. Maybe it doesn't make sense to run 6-cell VS 4-cell but from what Ive seen in this post so far, weight , cost, and anything else is nothing most of us didn't deal with 10-12 years ago.

The one track in your/our area that was around in the 6 cell stock days and still is around is the Triclone. The fastest 6 cell stock ever went was 38 laps, we'd already be running 39 laps in 13.5 if we ran 4 minutes and we haven't come close to reaching the full potential yet.

If you want to practice then come up to West Bend and race this summer.

P.S. Just don't try to run a 4300 in the 13.5 class.

I was running back in the day when the old 1200SC's were hot

This year at the Snowbirds they ran 6 cell mod and 4 cell mod
the 6 cell was only a tick faster than the 4 cell up front but fell at the end where as the 4 cell stayed close to their opening lap times and i think the 6 c only ran 2 laps more,
we run 4 cell mod indoors on the same track as the snowbirds and they are turning 3.5 -3.6 lap times.
Some of the guys are going to run the 3.5 and 4.5 brushless next month on the carpet and mybe with lipo's

ok thanks for you opinions, I didn't want to get everybody fired up about this. I just wanted to understand why they might have changed. I plan on running tri-clone this fall/winter after I put the big car away and get a CW chassis kit as I mentioned before I will not run that 10L4o ever again. I would like to come practice but travel is any issue till fall. Thanks guys and have fun racing this summer.

P.S. I will be running a stock 13.5 legally this winter!!!!

Me and a buddy strapped 6 IB4200 cells into our pan cars with Blue CO 27 stock motors just to see how much faster they were. We were not prepared for how fast they really were. They were virtually uncontrollable, and with all the excess voltage had incredible top end equal to ANY 4 cell wind motor I have ever used. I could honestly say it was faster than the 7 turn laydown brush Mod motor I had in my box. 4 cell stock times still are 2 laps off 6 cell times of 5 years ago probably because the power VS weight ratio is much higher using even 6 outdated cells of yester-year. LIPO cells should be equally insane. What then, 2 cells?

Most guys need a minumum of 3-4 packs for a race day, that would mean 6-8 additioal cells, where do you buy your cells that you can get 6-8 cells for 20 bucks? Please tell me where! Ralf

...I didn't see anyone respond to the part about "What about when lipos..."

We are trying to find the right motor combo right now to be ready for that day. Hopefully we'll find the right motor to run speeds close/similar to what 4 cell classes run now. We have found a 4300/10.5 motor runs very very close to open MOD times, the TEST MOTOR that was a 17.5 runs VERY Close to the current 10.5/4300 4 cell times...now it's a matter of finding the perfect "STOCK" type speed motor..which IS IN THE WORKS!

NOTE: ANY of these motor combinations, although nobody has talked about it.....would WORK With a 6 cell NIMH as well!!! hmmmmm

I only briefly raced in the 6-cell oval days before I took a break. Didn't you really need 6 cells in the 1200/1400/1700 era just to make run time without being very slow?

If someone is truly interested in running 6-cell stock, then I suggest running a class with stick packs to keep the cost lower (expect for people who will by 20 cheap batteries to find the best 3-4). I've seen the 6-cell stick pack/stock motor or spec motor classes work very well if run properly.

Actually the more cells you have the harder it is to make run time. Since the cells are wired in series adding more doesn't increase the capacity just the voltage. The more voltage you have the more current the motor draws and consequently the faster the pack dumps. That is part of why 12th scale road course racing (8 minute races) has always been 4 cell.

6 cells would be nice, but lets do some ozark hick math. 6 cells(1.15V avg) @ 1500mah would equal about 37260 watt/seconds or joules available.

4 cells(1.25V avg) @ 4200 would equal about 75600 watt/seconds or joules available.

The newer 4 cells have nearly double the available power that the old 6 cell NiCds had. I would assume stock motors are being engineered to use this power so the speeds are picking up too.

I wish it could be as simple as making a new motor series to reduce the speeds of car to allow new racers to get into the sport with less expensive crashes.

Whats going to happen in one year when the Nickel Metal Hydride battery is going to be replaced with Lipo batteries??

Heard that once the Nickel Metal Hydride battery reaches 5000 mah thats it.
The size of the battery is max out.

Get ready to switch back to 6 cell power (2 cell lipo 7.4 volts)??? :confused:

Its a good thing! ;)

Not to bust chops, but is this correct? I thought that a motor is a fixed electrical load and it's power is measured in watts. Volts x amps= watts. If voltage goes down, amps have to go up. So if you use more amperage, wouldn't the batteries be used up faster?

Yes, it was right. Your reasoning is incorrect. If you own a turbo30 or GFX go run a motor at 2V and at then at 4V and look at the amp draw. I'm not ambitious enough to explain, but you can use Google and learn how they work.

trailranger
06-01-2007, 11:56 PM
I'll leave this one alone for why amps go higher with more cells, but you can ponder

IR of cells is stacked so 50% more resistance
The free rev RPM of the more draws more amps at higher RPM?
Capicitiy is effectly lowered by the series circut by 50% (similar to resistance but inverted)

I'm not sure I'm seeing what your point is.

For a given voltage the free RPM of the motor is what it is. It's governed by the physical parameters of the motor.

Capacity is unaffected by a series circuit.

Lets say I have 2 batteries each is rated at 1 Volt and 1000 mAh.

If I place them in series I have a pack with 2V and 1000 mAh capacity.
If I place them in parallel I have a pack with 1V and 2000 mAh capacity.

So again the higher the voltage a motor sees the more current it draws, the more current that is drawn the sooner the battery dies.

Look up circuit theory and electric motor theory.

swtour
06-02-2007, 12:48 AM
Amp draw is HIGHER with MORE cells...cause guys OVER GEAR and because of the EXTRA battery power...they CAN~

OVER GEAR with a 4 cell...NOT enough power to pull it.

4 cell 12th scale guys always ran 12 minutes...yeah - LIGHT CARS, GEARED LOWER, etc.

When I ran a 6 MOD class using 1400 mah batteries we calculated we had roughly 23 amps of power to use to KILL a pack in 244 - 248 seconds. (Calculated to FINISH the Extra lap...if we came across AT THE TONE)

Current 4200's run for HOW LONG at 35 amps? 400+ seconds or something...so if the race is only 4 minutes (240 seconds) HOW many amps can you pull? 50? 60? But, how many do you NEED TO pull to be as fast as the track can handle...

pmsimkins
06-02-2007, 01:12 AM
The definition of overgeared is when you run a slower overall time then you could have if you had geared lower. If you gear up and you go faster you aren't overgeared whether you run 1 cell or 50. If you gear up and go slower then you are overgeared whether you run 1 cell or 50.

You don't get away with gearing higher because you have more cells. You actually gear lower with 6 cells versus 4. The reason for that? Like I keep saying the motor draws more current when you have more voltage. You must gear down with 6 cells because your battery will fall off too hard or dump altogether if you used your 4 cell gearing.

A good 4 cell car is just as able to pull too high of a gear (relative to the proper gearing for the number of cells) as a 6 cell car. What I mean by able to pull too high a gear is that lap times up front are faster, but the battery falls off too hard resulting in a slower overal run. This is true all the way from 13.5 (stock) up through mod.

06-02-2007, 11:35 AM
In my experience running both 4 and 6 cell stock runtime is less with 6 cells ever so slightly, not as much as the math would suggest though. my guess is that because the power vs, weight ratio improves so dramatically the motors may actually draw less or similar amps as 4 cell when tugging out of a corner. The motor is also producing much less torque when on the pipe at the end of a straight because of the higher RPM. and dont forget gearing is 50-80 points lower overall. I dont think runtime with todays batts would be a problem even with the hottest oval motor in 6 cell.

Part of your post is inncorrect pmsimkins! 12th scale road racing was always 6 cell, aswell a oval .

But there was 4 cell road course back in the day, it was primarily indoor's, part in due to the cars being too fast on the indoor small tracks.

12th scale road in general didnt go four cell till about the year 2000, because the rest of the world started running four cell at larger events.


-------------------------------------------------------------------------

on a different note*

I remember running 12th scale when the 10 scale pancar was introduced (1986 ), we ran 7 cell for 4 minutes. When the 7th cell was dropped, 6 cell came out and an increase in race length went to 5 minutes . Man people where nervous, in no time they figured it out and were faster with 6 cell then with 7 cells for an xtra minute.

I remember the stupid arguing back then, and for no reason. Everybody is bitch!n and moaning and within a few races of running Brushless and lipo they will be happy again till the next rule change!


Lets adapt and go racing!!

I want lipo 7.4 with a brushless 10.5 class.

It's been interesting to see all the different perspectives on the history of RC racing. I wasn't there at the BIG BANG, but I have been racing since the late 70s and the first four or five years were strictly 1/12th scale. As a matter of fact, 1/12th and 1/8th was the only thing available. 1/10th wasn't yet. I logged many many miles with 1/12th scale cars around the country, I have a hat full of Nationals and other big event hatpins from the early days and even raced in the 1/12th world championships in 1986. I have never attended a 4 cell 1/12th race...only 6 cell. Living in SoCal at that time most races were outdoor and always 6 cell. The one major event that did somehow elude me was the Cleveland race....odd that I went to college in Columbus and have many freinds in Cleveland, but that was another life. The Cleveland race is obviously 4 cell and a number of indoor tracks back East do(did) run 4 cell, but the vast majority of 1/12th was 6 cell. Hope this sheds some light on the subject.

No Hank all out door sphalt racing was six cell, I am remember running six cell road course from 1985 till about 2002 ,The last 6 cell stock race was at speedworld in Roseville Cali. I know I participated in the race! I was BQ.

The following year it was four cell at the paved on road nats in Durham N.C.
I remember because I was having a good battle with Scotty Ernst in the A main. It was the first time I ever raced 4 cell on Asphalt. :thumbsup:

True Gary's recollection goes further back then mine!! LOL!

I got some old magazines from the early to mid eighties and will try to scan and post some pics.

So again the higher the voltage a motor sees the more current it draws, the more current that is drawn the sooner the battery dies.

Look up circuit theory and electric motor theory.

From my understanding, if you have three 2V capacitors at 1F and have series circut then you have 6V potential with 2/3F capacity, but the same three is parallel you would have 2V potential with 6F capacity.

The interal resistance of cells stack the same as regular resistors, so 6 is 50% greater than 4.

I look at motors as an economic function, the free Rev wattage draw goes up as the volt increases. So the higher the voltage the higher the SUNK cost in operating that motor at that voltage. Which means, more of your capacity is spent to just keeping the motor moving whether or not the ther is a load on the motor.

why we don't run 6 cell- because a 4 cell 13.5 BL car at Easley, SC a cap asphalt oval, the 4 cell cars ran over 40 mph on the fast lap and ave over 39 mph for the complete 4 min run. How fast would a 6 cell or lipo 13.5 BL car be! 6 cell stock is about the same speed as 4 cell 19 turn. 19 turn went 43 laps, 13.5 BL is 3 full laps faster than stock at Easely, SC! Open mod ran 46 laps! That is why we don't run 6 cell oval anymore!

ok since nobody really wants to drop this subject yet, a few of you have gone on a tangent from the original question. People talk about cost and weight as to why we went 4-cell. If I remember correctly weight was 2lbs 10 ounces with 6-cell and with 4-cell the weight is still the same. Also cost was mention, well if you race other cars during the summer you could take those cell and run your pan car. There really is not that much price difference between 4 or 6-cell maybe $30 but if you already have them from summer racing other classes why would you have to buy new packs. Someone wrote that they tried running 6-cell with BL and could not handle the car, did you think to back off the throttle and set the car in the turn or did you just go barrelling in there? Back in the day a driver had to throttle his car to victory not just pull the trigger and turn left for 4-5 min. What fun this has turned out to be, you don't have a lot of punch out of the corner after bogging down the car in the turn. So what if you have to drop a few teeth on the gearing, if 4-cell is so much faster than why did we have to start running 40 something pinions and not staying with high 20's to 30's in 6-cell, either way works for me I just wanted to ask a stupid question. Maybe I should have sent the original post to ROAR and asked them why the changed the rule.

I seem to remember the ONROAD battle when the ROAR Nat's went to Speedworld on the 4 vs 6 cell issue..

The WEST Coast ran 6 and the East Coast I believe ran 4 - different parts of this country do different things due to seasonal weather (Not everyone like us CA guys get to race OUTDOORS in 70+ degree weather 11 1/2 months a year.)

As far as OVAL reasoning for 4 cell - I believe one of the biggest selling points that was brought up in that time was that oval was dying and it was very hard to get NEW BLOOD into the hobby because they could not drive the cars...when the OVAL Cars became specialty NARROW cars the became a lot harder for a lot of NEW guys to get a grasp on...and since NEWBIES have a short attention span, why not make it a bit easier for them to be able to control the cars.

At that time we had also worked out a SLOWER motor - but as so often happens, there were more than one iron in the fire and sometimes one good thing dies in order for another to move forward. (The 5 degree STOCK motor would have done virtually exactly what we were looking for to slow a entry level car down - and made a class that was actually kind of a HOOT to drive) however, the 5d motor was WAY too slow with 4 cell - even for a NOVICE driver....on any thing over about a 50 ft track.

With the idea of the LIPO movement - of course due to the increased voltage and projected increased speeds w/ current motors..that is why there is a push to develop a slower STOCK type speed motor for use w/ the LIPO packs...

NOT EVERYBODY WANTS TO DRIVE 1/2 throttle - some people don't have that kind of car control...and they won't ENJOY THEMSELVES..and will QUIT - That is why other things are and will be offered!

People talk about cost and weight as to why we went 4-cell. If I remember correctly weight was 2lbs 10 ounces with 6-cell and with 4-cell the weight is still the same.

--a 6 cell battery back in the day were around 12 1/2 oz, todays 4 cell packs are over 10 ozs a 6 cell pack is 14+ ozs.......making a 6 cell car around 45 ozs compared to a 42 oz 4cell car that has to add weight to get to 42 ozs. Cap Tires!

Also cost was mention, well if you race other cars during the summer you could take those cell and run your pan car.

-- A true oval racer doesn't run a righty car, ever!

---LOL you are wrong, we pulled the trigger as hard as we could. If you let off you got passed!

From my understanding, if you have three 2V capacitors at 1F and have series circut then you have 6V potential with 2/3F capacity, but the same three is parallel you would have 2V potential with 6F capacity.

The interal resistance of cells stack the same as regular resistors, so 6 is 50% greater than 4.

I look at motors as an economic function, the free Rev wattage draw goes up as the volt increases. So the higher the voltage the higher the SUNK cost in operating that motor at that voltage. Which means, more of your capacity is spent to just keeping the motor moving whether or not the ther is a load on the motor.

The capacitance of a capcitor and the capacity of a battery are completely different things. Also, as a side note 3 1F capacitors in series would have a total capacitance of 1/3F and in parallel 3F. But again, it is important to remember a capacitor and a battery are not analogous at all.

I'm still not sure exactly what your point is, but the last paragraph in principal agrees with me.

What ever happened to 6 Cell Pan Car Racing?

ROAR "Neutered" Pan Cars when they removed the 2 cells...that's what happened... :cool::eek:

SPEED alone does NOT make good racing. Ralf

If the stock motors weren't "cheated up" so much the speeds would not have gotten out of hand.Take the stock motor back to a full armature and stand up brushes and you could run 6 cell stock again.
