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.

the Power Jazz 63V should work fine with mechanical brakes right?

Yes, it will work. It also works with a pistol radio.

Is it difficult to get the Power Jazz to work properly with a Pistal radio.
I always run with mech brakes so forward only is fine for me and I may have to give this esc a try if progamming for a pistal is easy and dependable.

I heard from that the boat guys from rumrunnerracing.com, that it does work with pistol radio. Same with the Jeti/Hacker Spin controllers, they also work with a pistol radio.
