T-REX 500 › Which JAZZ ESC?

Trying to pick out the ESC for my 500 which I will run on 8S. So, it looks like the 55-10-32 and the 80-6-18 are the exact same price.

Everyone seems to be running the 55 but why is that when there is an 80 amp version for the same price?

Oh, I see a description on another site, looks like the 2nd number is the max lipo input cell count?

I'm running the 80amp one on my lepton and it's the best esc I ever owned! I have it on governor mode and it keeps the headspeed rock solid throughout the flight. It can only handle up to 6 cell lipos though.

the 80 for 6s, the 55 is for higher voltage setup like 8s or above

I will be running 8S and most of the other posts I've seen are running the 55 amp version.

If the 80 can only handle 6S it's not going to work for me.

Please excuse my post if you are already aware of this fact: I do not intend to insult your intelligence. Understand that as you increase the number of cells, the amperage is inverse and will decrease. Try to determine the maximum watts of your motor and divide by the voltage supplied by the battery you intend to use or measure with a watt meter. This will tell you the amp draw on your system. That way you can determine which speed control to use. If the 80 amp will support 6S, the voltage is 22.2V or 25.2 peak which is app = 1776W or 2016W peak. The 50 amp on 10S is 1850W or 2100W peak. This is based on a fully charged LiPo cell of 4.2V. Use the max amp draw or wattage specs of your motor to determine which ESC u need. I have two Jazz ESCs and I love them. I have a 55 and a 40. I use them on a 500 size and 450 size heli, respectively. They are super smooth and easy to program. I also have a CC35 it replaced. It has been years since I used the CC35, but I did not like it. They say they are much better now, but I need to update the software as they say it smooths out the governor. The CC ESCs do not have very good BECs as they overheat and even melt the shrinkwrap. They also cause glitching because of this. I have never had a problem with the Jazz BEC. It is a switching ESC. If I misstated anything, somebody please chime in.

Sounds good, the 55 it is.

Now, anyone have a coupon for 50% off?
