Possible Kontronic HV purchase...

[Serum]

Great info. Will try that controller with a low KV neu.

Good info on the motor as well. Do you know what type of segmented rotor they use? sliced or sintered?

Sounds like the motor is less ideal than i hoped for. Guess the price says it all, you get what you pay for, right?..

What is the car extension?

So the motors are not a good a a neu, but i am sure that they are better than a feigao motor?!

The only problem I had with the Jazz 55 was when I tried it with the Align 600L motor on 36V. It stopped working, but I guess it was my fualt. I ran the 40 HV controller with the BPP truck and the only thing that went wrong with it was the capacitor. Kontronik makes solid controllers, but the price is up there as well.

What about this monster? http://www2.towerhobbies.com/cgi-bin...&P=SM&I=LXSDV4 It ha scar software also?

The Power Jazz 63V doesn't have car software. I tried asking Mike at Kontronik if he can add the car software to it and he said it would take 4-6 weeks, but I haven't heard anything yet from him.

I would like to get a Power Jazz 63V, tell him you know another person interested in getting one, maybe it will speed them up. PM me if you hear from them
Thanks

He is not replying to my e-mails LOL. I even went to rcgroups to ask for it there.

@lincpimp
with "car" extension i meant those ESC which have "car" at the end of their labelling -> Jazz 70 "car".

The Fun 600 motors are somewhere between a feigao L can and lehner/Neu. We already discussed the Fun 600 motor in this thread.

@Serum
I posted a picture of the rotor (from kontroniks website) on the above mentioned thread. Maybe you can tell from the picture if they are sintered or sliced. They for sure are not as segmented as lehner rotors and don't look sliced to me.

Before using a neu 1521 with 10s1p A123, i tried a fun 600/11 (1100kv) which only survived 4 runs (it was preowned so maybe it already had some kind of issue). Right in the middle of my last run with the fun 600/11, rpms rose dramatically and i couldn't start the car from a standstill without cogging. On my eagletree graphs i had Amp spikes of 70A (around 1800W). Before this event it never drew more than 40A. Temperature measured on the heatsink was at 65°C (149°F). So maybe i possibly demagnetised the rotor or a wind shorted because the seal overheated. I never expected this to happen (not at this temperature level). So what i learned from this lesson was: you have to properly cool those Fun 600 motors. The fun 600/11 would have needed a fan on top of the heatsink.

Those are the graphs from the last run of my fun 600/11
-> look at the last rpm spike at the end


-> before i understood what has happened i tried to spool up the motor a few times: look at the amp draw (Watts), RPMS and motor temperature


Don't get me wrong. I don't want to say those are bad motors. My fun 600/25 still runs great today, but it gets hot and needs good cooling. After a 10 minute run in my Ezilla i can't touch the motor longer than for 1 second although i use a 50x50 pc fan above it.

I ran the FUN600-15 with 10S A123 on my BPP truggy and it lasted a little longer than yours. They are good motors, but I think the Neu is the way to go. I had my first downfall with my old 1412 1y Aveox, but it is only the shaft that came unglued.
