Kontronik Jazz 55-10-32 for 8s buggy;-)
 

Hello fellow rc-addicts!

I bought a used Kontronik Jazz 55-10-32 today, hoping to do an HV buggy setup.

I have been reading about HV setups for 1/8 buggies and trucks, and I have seen several people have success with and recomend the jazz. Othello among others.

If I have understood what I've read and heard, the jazz can be used in cars with pistol-radios without a "pistix"? I will need a bec, which HV bec do you recomend? I only know of the CC bec-pro. Or am I better off with a reciever lipo?
Is there anything else I need to know?

The jazz will be used in my tekno eight with a medusa 36-60-1300kv on 8s. I have also bought a used MBX6 to connvert, maybe I will leave my tekno 8ight on 6s and give the HV setup to the mugen.

Thanks for any help or advice.

1300kV would be maybe a little too much for 8S 60mm motor no ? Put a small pinion !

Comes highly recommended :)

Solid controller and a 1000-1200Kv would be ideal. I used the 40A 10S version in my heavy truggy and it lasted a long time. The only thing that I need to do to get it going again is solder a new capacitor and the + wire. My 55A never had any issues and they are very under rated controllers (A heat sink is recommended though to keep temps down specially with the high starting power a vehicle needs). I would recommend a RX pack though. I use one with all my HV set ups. I just wish Kontronik would have the same features as most car controllers do nowadays.

Thanks very much for quick input!

I am happy to hear that the esc is good for cars and pistol radios, even though I was fairly sure, I wasn't certain. Needing a pistix, that aparantly is not easy to get anymore, would have been a bummer to say the least. Thats why I didn't get a castle esc, even though I got offered a good deal. Luckily I got an even better deal on the jazz:yes: 60 dollars max in norwegian kroners.

I know medusa 36-60 1300kv is a bit high kv for 8s, but so is 36-60 1600kv for 6s and that setup works perfectly in the tekno 8ight now. Its geared low at 13/48, with 12/50 as the lowest option. Using the speed calc I found that with gearing at 13/48 both setups give the same speed at 40mph. Thats why I think it might work, after all people run their castle/neu 2200 and 2650kv too on 6s. Now thats madness IMO, but madness seem like fun I admit that:yipi:

Also, I have the 1300kv on the way, it should have been here before the 1600kv.... I ordered the 1300kv and the new one piece, 3-shoe clutch adapter w. shoes, bells and all from impakt first. Then I was not sure if it would maybe be slow, so I ordered a 1600kv too from mike the day after the 1300kv shipped and figured I would always need a motor. Nice to get one more while they last too.

I hope the setup will work, I have some help from the motor-mount transfering alot of heat from the motor and using the whole chassi as a heatsink. The mechanical brakes with 0% brake set on the esc/motor will help ease the load too. And I imagine the clutch makes accelerating from standstill easier as well. I don't know if it will make that much difference, but I have a feeling these things are part of why the current setup performs so well and stays cool.

Even if it all works out, I will still be looking at used motors in norway for a milder kv. I remember seeing a medusa 850kv, and a 1515/2Y/F sell not long ago.

Long post, I appreciate any input, thanks,

Solid piece of hardware. Mine even worked without heatsink used in my 3.9-4Kg Buggy with a Neu 1512/2Y (1400kv). With heavier vehicles a small heatsink is recommended. I fed it with 9-12s A123 (11-12s with a Neu 1515/2Y - 1100kv).

A more up to date software would make it even better as Lutach already mentioned.

I would not worry using a 1300kv motor with 8s lipo (as long as you can gear your car for higher motor rpms). My old Crono buggy used a 52t spur (more likely to be found in a truggy nowadays) and had an overall gearing of 1:13.2 with a 13t pinion. Perfect in conjunction with a high revving motor in a buggy. Tons of power, low amps and long runtimes. My Neu 1512 with 1400kv reached well into the 42000-45000rpm range and stayed reasonably cool.

I have read a little bit about programming the jazz, and one thing I notice is that the manual is very hard to understand. I see one needs a jumper to program it manualy, I didn't get one. Is it supposed to short the three pins? I could make my own then...

I hope its not too much to ask, but could any of you kontonik experts write up a quick set-up guide for lipo powered cars, I tried searching but I only found quides for heli setups.

Thanks for you help!

Get a jumper (You only need to short 2 of the pins) and programming the ESC is very easy. In the manual, the car modes will be on page 16 to 18 (for German) and 40 to 42 (for English). I'll copy and paste from the manual:

Programming sequence of Car-Mode Race: (Mode 6)

Affix the jumper on any two of the 3 pins.
For an audible signal connect the motor to the Jazz.

Turn the Tx and the Rx. Set the throttle
to motor-off position (middle position).

Connect the battery.

Wait 2 sec. or until 3 signals.

Remove the jumper.

You should now here this signal sequence:

1 signal, 2 signals, 3 signals (descending) and 6 signals.

Set the throttle to full speed (front position).

You will then here 3 descending signals.

Now set the throttle to EMF-brake position
(back position)

You will again here 3 descending signals.

Monitoring output and 6 signals.

Ready - Disconnect the battery.

Programming sequence of Car-Mode Back and Forth (Mode 8)

Affix the jumper on any two of the 3 pins.
For an audible signal connect the motor to the Jazz.

Turn the Tx and the Rx. Set the throttle
to motor-off position (middle position).

Connect the battery.

Wait 2 sec. or until 3 signals.

Remove the jumper.

You should now here this signal sequence:

1 signal, 2 signals, 3 signals (descending) and 8 signals.

Set the throttle to full speed (front position).

You will then here 3 descending signals.

Now set the throttle to EMF-brake position
(back position)

You will again here 3 descending signals.

Monitoring output and 8 signals.

Ready - Disconnect the battery.

Lipo Mode (Mode 9)

This mode is programmed additional to change the under voltage disconnection to 3V/cell when using Lipo batteries.

This mode does not change any other feature programmed before. During
programming wait on 9 signals, all others like programming mode 6 and 8.

Mode 9 only works if any mode except mode 1 has been programmed before.

To avoid misunderstandings the start up signal changes to 3 signals, 3 signals when the Lipo-Mode is active.

Caution: The programming of Lipo-Mode enables the under voltage disconnection also in modes where it is normally disables!

Thanks! I remember reading about a usb link for the jazz, so I can program more advanced features and see clearly what settings I have? Where can this be found?

TG

The Jazz line is not programmable with the USB. If you have the latest firmware (I don't know which one it is), you can use the program card(s) for it. I don't have the program card and to be honest, it doesn't really needed it unless you want to fine tune your LVC.

Do you know where they sell these cards?

Thanks for all your help,

Thomas G

Contact Kontronik first to see if you have the latest firmware. The ProgCard I is for the Jazz ESCs. If your Jazz is compatible with the ProgCard I, you might also be able to use the ProgDisc. It's also best to ask Kontronik if the ProgCard and the ProgDisc is necessary as I don't think it is.
