|  ESC cooling?
I've noticed a few pics on this board of people running cooling fans on their crawlers. I'm guessing they're for the ESC. Is this true and how neccasary is it. I"ve run my Novak Rooster for 45 minutes and never had an issue.

On the Super Rooster, it really isn't necessary if you keep the motor at a high turn. Although, when it comes to ESC's, cooler is always better. It will last longer if you always keep it cool. On the other side, you could use a "lesser" ESC, such as a regular Rooster and run dual motors off of it if you use a good cooling fan. Obviously, in that case the extra cooling is probably necessary but it's hard to say. What set up are you using with your Rooster? Two motors? |

my personal opinion is that most people think of their equipment like a human. if it's hot, it's not good. But our automobile engine runs at around 200 degrees. it's designed too. Modern semiconductors are well within their operating range at elevated temperatures: EXAMPLE: http://www.nteinc.com/specs/2900to2999/pdf/nte2967.pdf NTE High Speed Switching MOSFET Channel Temperature Range 150 Celsius that’s 302 degrees Fahrenheit!!!!!!!!!!!!!!!!!!!!!!!! this is just my personal opinion, but i never run and have never run cooling fans on my equipment, with no problems. I have modified circuits and performed tests on semiconductors and run them up to very high temperatures, with no failures. In addition, most high cost electronics today have thermal protection circuitry. BUT, it is advisable if you are pushing an ESC past it's limits, such as using a rooster on two motors. But a super rooster on two high turn motors will never even get "hot" in semiconductor terms. just my opinion. |

Ya, running a fan if your ESC is hot is good but if it is not there is no need. The fan is also a pain to hook up. You need either a y adapter or another pack.(battery)

Digler, I'm just using a single motor. I've never had an issue but I noticed some pics of people running them and was curious if I needed one. Since I'm building my TXT crawler currently I thought I'd ask. Thanks for the info guys.

I'm thinking of running two 55turn singles, wired in series, and hooking it to a regular Rooster. Anxious to see if it works.
