What kind of temps should I be running?

[roadrashracing]

I trying to get a setup in the ballpark, what are good temps for, batteries, motors, and escs? I have heard so much different stuff.

There are so many different set up's and prop choices that will affect temps on everything. for me... this is what I like to see:

ESC: 90-120
Motor: 90-125
Liops: 100-130 (When you ger higher than 140, you will either puff it and if not it will be too hot to hold...this is not a good sign) Note: aim for a 45c or better Liop rating.

Make sure you have the largest size (Inside diamater) tubing and if you want run 2 seperate water lines it can help keep each item a litte cooler as if water is to warm before it gets to either the ESC or Motor (depending on how you have it set up) you will get "fresh" and "cooler" water for each item.

You will find that depending on the KV of your motor and Prop choice (size and pitch), temps will vary as will speed. Another thing that I do is to pre fill the lines before start with Ice water. Water temps in my area are really warm (75-80'ish....mostly in the ponds...lakes are a little cooler). So what ever I can do to keep these items cooler, for me the better.

Is that deg Celsius?

No F degrees.

Taking temperatures of electric components is almost useless unless you take them within one minute of pulling the boat out of the water. The ESC in particular will cool of rapidly. Most motors will be fine up to 140*F taken on the endbell (through the holes in the endbell if present). Caps on the ESC under 140*F, they will be the hottest part. Most LiPo makers recommend not exceeding 140*F, although some cheap packs will puff below that temp (premium cells will not). OF course the lower your temps the better, but be realistic.

Since I often run in ambient temperatures above 95*F and surface water temperatures above 90*F, I almost never see temps below 110*F after several minutes of running. I race most of my stuff so I'm pulling plenty of amps. If everything is under 135*F I'm happy - but I will prop down or shorten run times in hot weather. It has been a long time since I burned up an ESC...
