e-Electric Motors & Controllers > Jazz 55-10-32 Question

I have a new Kontronik Jazz 55-10-32 (55A, 10-43V) esc.

Can I use it as a replacement to the standard Align esc that came with my Trex 600?

I'm using a FlightPower EVO 20 4900mAh 6s1p 22.2V battery.

Thanks

Been there done that!

Yes. The Jazz 55-10-32 is an amazing controller.

Jazz ESC

The Jazz 55 ESC is a HIGH VOLTAGE controller....meaning it is really designed to be used for 10s applications...

If you try running that on a 6s trex 600 setup you will FRY it!

that jazz controller can handle higher amperages than it's rated 55 amps...but you're rolling the dice...Personally I would get a higher AMP rated ESC for a 6s setup...like the 85HV(I hate having to recommend Castle Controllers) but it's the best fit for your heli..

I'd hate to see you ruin such a nice 270$ controller like the jazz 55..

I've seen people post that the Jazz 55 have seen 100A and more. You don't need to run 10S only because it's a HV controller. The controller will not fry with 6S and if that is the case he'll need to run 12S with the HV85. If he's using the original motor(s) which draws something like 65-70A, he'll be ok. I used the 55-10-32 with my 1/8 scale truck with 6S and it did a wonderfull job. I know people who ran 8S A123 and 10S A123 that have seen spikes of well over 100A and the Jazz 55 is still doing what it should do. The price yes it is high and that's the only minus for a solid controller.

OH BOY!

Another Jazz expert here...

the jazz 55 does not NEED to be run on 10s ..I never said that...I said it's designed to be a HIGH voltage controller..meaning it's rated at 55 amps ....I too have heard of people spiking them at over 100 amps..

But if you notice what I said..it's like rolling the dice..you're gambling with a VERY expensive controller...It has nothing to do with voltage...it has to do with the simple rules of electricity..

Higher voltage requires less amperage to make the output wattage...lower voltage requires higher amperage to produce the same output power..for expample(using simple numbers)

a 40 volt setup that pulls 50 amps creates 2000watts
a 20 volt setup requires 100amps to create the same 2000watts of output..

The jazz 55 can be used on 6s but it's not the right tool for the job...I recommended the 85hv because the 85hv is rated at 85amps continuous...

I'm not here to argue...I just wanted to share a small amount of what little knowledge I have


BTW...I have 6 jazz esc's on some of my helis..Including 2 powerjazz esc's...so I guess you could call me a BIG FAN of the JAzz esc's

Yes, but it might fry on you.

I run that controller on 2 of my more powerful birds, but on 10s, and wouldnt dream of using it on the same size with 6s, cause of what he(jag72) said.

You need to do the math and have a working knowledge of the topic. ie If your running anything electric, knowing your power-structure and its capabilities/limitations for the work needing to be accomplished(hovering, 3d, etc) is paramount.

Thats the best advice I can give you....but some just want to fly, and not know why.

Most German ESCs like Kontroniks and Schulze are under rated for amp draw. The Jazz 55-10-32 is really meant to be an all inclusive high power ESC, as the number 55-10-32 means 55 amps continuous, minimum 10 cells Nicd, maximum 32 cells Nicd. I have been running 55-10-32 on my 600 since its maiden. When I was running 6S it pulled closed to 70 amp constantly during 3D and never broke a sweat. Later I switched to 10S and dropped about 20 amps, it ran even cooler. I still have a Kontroniks Beat 50-10-30 on my Raptor 50 conversion and it doesn't mind 6s or 10s or 24s Nimh.

The Jazz are pretty bullet proof. If you overamp it will shutdown instead of cooking itself.

BTW, I would take Castle's ratings with a grain of salt. Based on their specs, you should be able to run a non-HV Phoenix 80 ESC on 6S in your 600. But we all know how that ends...

reading these posts is scaring me a bit.

i am using a 55-10-32 on my swift with a 10s a123 setup. after the initial spool up, the voltage drops to around 29volts. i have seen spikes to around 75amps, but no problem yet.

10s a123 puts out much lower voltage compared to 10s lipo (29 vs. 37v)

any comments?

I wouldn't worry much. I know people who are using the 55-10-32 and seeing upwards of 120A. You will not fry it. I used mine in my truck and it didn't fry. I know of others who are also using it and have seen spikes of 120A and it still working good.

this is how my amp/voltage draw looks like ...

If you are running only a max of 6 Cell count I would highly suggest the new Kontronik Jive LV100, that would be your best esc for 6S and under. I-Care is carrying the new LV series.

...Once upon a time there were Nitros, flybars and frequency pins...

Jive80 won't arm

Hi.
I recently purchased a Jive80LV ESC. I installed my connectors, removed the red wire to disable the BEC. I hooked it up to the motor and Rx. Turned on my TX.(JR9303 with spectrum air module), turned on my RX(Spectrum AR9000) with a seperate battery and BEC. Plugged in my 6 cell lipo (5000 mah at 24.7 VDC measured at the deans connector). I received the arm signal so I bumped the motor to check rotation. It moved for a second and then stopped. The motor would not go after this. Now when I plug in my flight battery I get 6 LED's flashing. The trouble shooting guide says 6 flashing LED's is " Hardware Reset because of too low voltage ". My battery is charged. I don't know what I'm doing wrong If I am at all. I have a linear throttle curve and my end points are good. It did arm the first time. It will not arm with a 3 or 4 cell pack either. When I do hook up a 3 or 4 cell lipo I get a single LED flash. Do I need to purchase a program card to reset the ESC? Any help would greatly be appreciated. I'm using this ESC in a Trex600.

Buffy.

I am having exactly the same problem. I did removed the red wire because I use a duralite voltage regulator. No work any more.

You can see my settings in the previous post.

I am really disappointed because I paid a fortune and now
the jazz has turned out to be a ****.

Hope we can finally sort it out.

Cheers
