1S is a lot shorter than a 2S pack, so you have room to mount the ESC and receiver on the battery side. One possible way to do it.

Why would you buy three 2s packs? It's easy to race two classes at club racing pace with just two packs. At big races, you only need one pack.

I dont understand though, Why go 1s when you can go run something like a 8.5 or something of that sort and just run that? Even if it isnt much faster or any faster then a 13.5 with timing advance (im not sure), you wont have to worry about good lipos, timing advance, and new motors.

Seems like going to 1s solves some problems. And creates more. I wouldnt think a 1s lipo would like a 4.5 or a 3.5 in a TC very much. I guess it would be a good test to see whos lipos are rated true

No, it is not. You're assuming that the change to 1s would be the only change. If the change were to happen, racers would change motors to regain the speed. If you take away volts, you must increase amperage to get back to the same power output (wattage). Now you're thermalling and 5000mah doesn't seem like alot any more. 1/12 can do it because the cars never needed much torque to get them going.

The new speed controls are killing spec motor classes. What's funny to me is that they want to go faster at any expense but are scared to run mod.

Yeah one way to keep the timing advance speedos from affecting mod is to make a like you said an 8.5 the motor for spec mod if you called it that or something. 8.5 on many tracks is to much. Heck even 10.5 that is evident. As this would be plenty fast and lead to throttle control of the driver or to de-tune the motor so it did not have the full speed out of it. Like running a much higher FDR or reducing timing a bunch.

What I think really needs to happen is ROAR needs to go back to the rules for TC and modify them sooner than later here to somewhat save the TC scene. As it is right now with the newer technology it is really making drivers rethink about running TC.

I'm sure 1 cell lipos will help out RC like brushless motors and lipos did.

this is an expensive hobby, but it is so much cheaper than it use to be since brushless/lipo.dont think 1cell tc is a good idea this is part of the reason that no one races, to many people want to change to many things and their is to many classes which divides to many racers. low turn out at big races maybe because of high entry fees.

You do not increase amperage. It is relative to resistance and voltage. The only way to increase amperage is to increase voltage or decrease resistance. That is the ONLY way you can increase amperage.

Default Why when..

Why, when almost all of us racing touring car already have the LIPOs, the motors, the 2 cell chassis, the wind motors for the class we enjoy..

If we used 1 cell:

All new Chassis to make the 1 cell balance.

Throw away our $100.00 2 Cell's.

Find the Spec Wind's.

Prevent the people that already invested in 2 cell stock racing from bailing out of racing, just because we told them they have to reinvest to race.

Develop a enough of a following so that spending cash on 1 cell TC would be worth the time.

Get ROAR to develop a class for it.

Prevent VooDoo ESC's from entering the playing field.

Make it fast enough for the true "Open Modified" drivers.


I like that people are trying to come up with new way's to grow touring. But why. I don't hear that many people complaining. True, for new people it may be cheaper. But a lot of us have our money already in. Don't wanna spend twice.

dodgeguy, the point you are missing is that, in order to compensate for the lack of power that the same motor would have on 1s, people will run a motor with fewer turns. Fewer turns raises the kv and lowers the internal resistance of the motor, both of which cause it to draw more current. Since racers would want the 1s racing to be only a bit slower than current classes, that is only a bit less power, amperage would be way up compared to what we run now.

I am not missing any point. You need to go back and re-read what I was saying. Yes a 3.5 turn motor has less resistance because there is less wire than a 13.5.
Fewer turns already reduces the internal resistance not KV. KV is a measurement.

I was pointing out to David that you can not create amperage as he implied.

The problem I have is the spec part. I like stock. We have 4-10 17.5 Tc guys every weekend and we finish in the same order we did when we ran brush/nihm. The fast guys win, the slow guys finish behind them and the hacks break their cars when they hit the walls.

Are you guys trying to build a spec class or a stock class? If its spec them do a spec class. If its stock then show up with your 17.5 and drive your ass off and have fun enjoy your friends at the trank and try to earn the bragging right for that weeks win.

Once the Esc wars are over we as racer will work every waking hour trying to sqeeze another tenth out of some part of our car/electronics/tires or what ever else.

Just run what you have or spend a little more and get the lastest.

Playing is cheap Racing is expensive!!!!!!!

New technical rules won't bring touring car back up the top of the R/C ladder. Making touring cars vehicles that people can have fun with will. Make them more realistic and more durable. That's what will make new guys interested in them. All we need is the on-road equivalent of the MT or the Slash. Something that is fun and brings in new people. From there you can make things more complicated with tons of rules. New people are scared off by the complexity of racing TC. We should make the rules for the classes us experienced guys run in suit us best. Then give the entry level classes rules that work for them. Anyway that went a bit off topic...

1S1P. Imagine how simple (also see inexpensive) we could make the chargers! No balancing or fancy stuff. Battery wars are what I see on the horizon with 1S. Just imagine when the 5500mah pack comes out to replace the 5000mah pack and you can gear that extra bit taller for more power and still finish the race, where Mr.5000mah will never be able to run at that speed without dumping. Is that worse than ESC evolution? 3-4 new packs a year or 1 new ESC a year? Well, there could be more ESCs per year of course, but ESCs are also reprogrammable, and batteries aren't. Battery development could be slower too, or frozen in the rules. Frozen capacities would lead only to absurd and insane battery voodoo becoming par for the course. An extra 200mah could be worth a couple seconds over 6 minutes and racers would do anything to get it certainly.

Onto rant #3:
How to make touring car better for new guys.
Make the IFMAR WC A mains really long. That way the manufactures will be required to make their cars really, really strong to survive. The only reason 1/8th buggies are so strong is because of 1 hour mains. The cars have to survive to be competitive. This has the side benefit of making the car inherently beginner friendly. Minimum weights will never make cars stronger because it's faster to add lead to a car than to make belts wider, or add gear diffs, or thicken suspension arms.
1. 30 minute mains at all IFMAR WCs. Hard barriers necessary (N.A. style).
2. Gear diffs mandated standard.
3. Minimum 6mm wide belts.

My slightly odd $0.02
