Is 20c enough?
#2
the c rating is the discharge rate...20c is fine for tenth scale use...I use 20c for my mod(3.5r) motors in 2wd truck and the batteries dont even get warm...25c is better but in tenth scale 20c is fine...

I raced 2wd truck mod w/ a 15C battery and it's more than enough. I've recently bought SMC 28C batteries though to give my Slash more punch. 20C is more than enough for most if not all 1/10 applications.

I run an Orion 3200 20c pack in my XXX-4 mod... It is plenty fine! I have run everything from a 3.5bl and 9t brushed single... I have tried other higher C rating LiPos and find NO difference in power or handling.
I think it comes down to the quality of the packs. Most of the guys at my track that complain about lower C ratings are using cheaper packs. Nobody seems to complain at all about their Orion/Kokam packs.
I think you get what you pay for.

from my 4900 25c compared to my 3800 30c i think there is a few minute difference between the two. i havent looked at the clock before and after but the runtime is noticeable. the 3800 is lighter and i think faster too. with a 17.5 motor i could tell a world of a difference because im clearing jumps a foot farther with less of a running start.

Do I need to say it again
Many people think that, but it is wrong; the C rating is used as a reference to how many amps a battery can supply i.e 5000mah 20c can deliver about 100 amps or a 3800 35c can deliver 133 amps 
So unless you are running a super high amp drawing car the C rating is just to bring in the money

Your ESC could also shutdown if it cannot get enough current, not really a problem often but it can happen. Get the highest C rating you can afford, as higher C ratings also means higher quality lipo cells (usually, not always).
