Trenger ny ESC, trex600

[retlaw]

Har nå brukt et par timer på å skrive en klage. Noen som gidder å ta seg litt tid til å korrigere mine dårlige engelsk kunskapene:

Hello. I did buy a Kontronik JAZZ 80-6-18 speed controller from you and believe that it came with a manufacture fault.

Order: 14974, 1./20/2008

The first thing I did after I have received it was to connect it to the Kontronik program card and a 4,8V battery and tried too program it. The light diode from the controller and program card did both work as they should. After I solder the deans connector and banana plugs, I installed the ESC to my chopper and connected it to the receiver. When I connected a 6S Lipo battery pack, I sow smoke began to rise from the ESC and quickly disconnected the battery pack. After a closer look it’s seems that the JAZZ speed controller have taken permanent damaged. Surprise over it I started to ask myself why this have happened. Could it be a production fault? Have I changed the polarity when soldering? Or did something else in my helicopter cause the error?
After a second closer lock of the polarity to the ESC and battery booth seems right. On the JAZZ ESC you can see that the burn damaged is on the motor side. Sow I started to suspect that I had a motor error to find. I have now spend most of my weekend testing the Align XL600 motor with the receiver (Spektrum AR7000), servos (3 x Hitec HS6975) and gyro (GY611 & 9256) connected together.
I have used a 18A brushless ESC and a 60A brushless ESC during testing with any problems. I did only use a 3S Lipo under the test because none of the ESC could handle a 6S pack Lipo. I have also measure between the motor cables with out finding a error.
Do think it matters, But the Jazz controller owner manual does not tell the motor cables (red, green and blue) polarity. I connected the coolers red with red, blue with blue, and green with black(Align motor).
I hade also the Align 6A BEC connected to the receiver battery connection socket, but the 2S lipo pack was NOT connected to the Align BEC. I hade also the Align BEC connected under the motor test with out problems.
I have now read the owner manual several times and can not find any thing that tells me that I have done something wrong to damage the JAZZ speed controller.

Kontronik have a 24 months warranty, sow I expect a solution to replace my new, but damage Jazz controller.

Best regards
Walter Fischer

Fant endelig feilen nå som jeg hadde gitt opp og har kostet meg to ESC og en s9256 servo .
Med drevet og resten av mekanikken montert sammen var det vansklig å oppdage, helt til jeg fikk den nye 1700kv motoren i dag. Sammenlignet de to ved siden av hverandre og når jeg dro rundt rotoren på den nye og gamle oppdaget jeg at den gamle var skikkelig treig/hard å rotere rundt i forhold til den nye.

Nå er det bare for meg å vente spent på hva espritmodel svarer meg på mailen ang. kontronikk jazz 80-6-18 som aldri fikk sett dagslyset. dakkar

Beklager å måtte skuffe deg, men dette er faktisk normalt.
det ble skrevet om det på helifreak også(gidder ikke lete opp posten) nemlig at xl motoren har mye mindre "cogging" enn l motoren....

Nå er begge disse motorene Xl versjoner, men den ene er på 1650kv og den nye på 1700kv. Men så tung som den var itilegg til lyden som kom før Align ESC brant så tror jeg forsatt at det er noe gærnt med den..

hehe, den høres ikke helt frisk ut nei

Takk til Espritmodel

Fått svar fra Espritmodel og litt skryt skal dem ha



Hello Walter,

Thanks for the email.

Sorry for the delayed response.
Our head heli guy was preparing to leave for the Nuremberg Toy Fair and we
are stretched a bit thin.

In short, I agree that something is amiss with your Kontronik ESC. This is
very, very rare.
Please return your controller to us and we will replace it for you.

With your next one though, if you are going to use an external BEC, you will
want to disable the BEC on the Jazz.
Simply remove the red wire from the receiver connector and tape it back
against the rest of the wire. (In case you want to use the BEC later.)

As for the motor leads, there is no proper polarity. You can connect any
color to any motor lead. Other than its rotation direction, the motor does
not care what lead goes where. In fact, the most common way to reverse the
rotation of a given brushless motor is to swap any two motor leads.



Please let me know if you have any other questions or if I can help with
anything else.



Thanks,

David
