Well when some of classes are getting so exspensive, competators start dropping like flies. No matter how much money I spend on my racing, if I have nobody to race, what's the point?

At that point, people start making the point to worrie about driving. Joe blow racer is not gonna look at his driving skill, he will look at his equipment. It's the human way to point and blame. Eventually, people spend so much money they could have just went out an bought a go kart..

For people like me, that don't mind spending all kinds of cash on the RC hobby, it's not a big deal. I love having new stuff. Girls go to the mall and buy shoes, I go to the lhs and buy new RC stuff.

No offense taken on my part. There is nothing worng with buying horsepower. I will say that I am not so sure that "everybody" konws driving better equates to faster. I truly believe that there are racers out there who really believe that their slower lap times are due to short comings of their equipment. I will also say that just because you buy the horsepower to make the car faster, you will not automatically drop your lap times...at least that has been my experience. Believe me, I wish I could buy a can of lap time reducer...I'd stock up for sure!!!

Is there any youtube video showing 50C battery is being discharge at 250A ?

( I think the battery will explode ! )

Someone should make a string of 125 light-bulbs and put it to the test. Given SMC's 90% factor, a 5000mah pack should hold voltage above cutoff for ~65 seconds.

BTW: You better direct solder the battery in-line and use a seriously heavy duty switch to keep things from melting...

Now, with blackedout venturing into mod, the benefits a good pack made in 13.5 (stock classes in general) may not be as noticeable in the fast guy class. For a driver like myself who is still trying to get used to On-Road, it may just be that I plow the wall that much harder in 13.5.

We will give them a whirl

I am new to the whole lipo battery after being gone from rc for a while. Now having gotten into racing TC, I do see how better driving makes all the difference. But a good lipo and brushless motor is a world of difference within itself. For someone new and someone totally disconnected from reality or a pro, would think that the equipment is gonna be the hot ticket. But unless you are running something older than god, I can't see how this would be true. I have gone from running a 7 year old car to this years model and it did make a difference. but my driving still sucks. The equipment for me, was nice to have and it did make driving a bit easier.. Faster? Probably. But when you start at the back of the pack racing an old car and then go to a new car and be a bit closer to the second to last person, equipment doesn't matter. Driving does.

After talking with people about the c rating in batteries that I should use, I was told that the lower c rating for running 17.5 stock class, it is good enough. The higher c rating is best when used with mod motors cause they turn much faster and draw much more current. With this and last years addition to timing advance within the speed controls, a higher c rating is needed. This is what I have been told. Sounds logical. The logic behind a warmer battery flowing electricity sounds logical as well but common sense tells me that whenever a battery gets warm it is because of draw. I don't know that a warm cell flows current better. I know I get around alot better when I'm warm. But I'm not a battery or an electrician so hopefully someone can explain the necessity of having such high C ratings for different classes of motors.

I'm not really one to put the time and effort into testing resistance and such on my lipos, but I can tell you in a side by side comparison, in a t2 009 with sp gt 2.0 and a lrp x12 17.5 I can't tell the difference in my 24c smc and my epic 40c. So, as far as I'm concerned I won't be buying anymore 40c or higher lipos. I'll just still with a reputable manufacturer and be happy!
