Someone jump on this deal!!!KonTronik
 

Hey for all you guys looking for really good deals for high quality motors


this is not my add but it is sure worth it

Based on what I've heard, the quality of the Kontronik motors is equivalent to the quality of Feigao motors. This motor reminds me of the Feigao ferrous-loss free 580 6 pole motor.

Umm, where's the deal? The Fun600 motors have always been that price.

Yep, the kontronik motors are not worth 2 bills. Thier escs are nice. That is the same price that they always are. Now if you know what tower pays for them, well you would laugh.

No offense to you, BrushlessBoy, but you probably thought that since the motor was "big" it's a deal at $190.

Actually it is about the size of a L can feigao. So not that big. Probably a good buggy motor on 6s.

It's more of an L sized motor indeed..

Also $40 cheaper here...

Our own Sherlock..

I was about to say the same thing! Arct1k certainly does find some stuff, he must have nothing better to do, or an army of trolls that do his bidding! All he has to do is command them, "find kontronik motors cheap" and they will!

Opps sorry guys, i thought there quality was up to par with there speed controller, srry for that :D :slap:

I like my FUN600s. The FUN600-1700 worked awesome with 36V for a while. They are higher quality then Feigao.

I dissassembled my Fun 600/11 which i used in a 1:8 buggy with 10s1p A123. It only lasted a few runs. On it's last run it kind of overheated (hot sommer day) while the temperature probe of my eagletree recorded 70°C (158°F) placed on the heatsink. RPMs suddenly went crazy high. The motor started to cogg at startup and it sucked twice the amps it used before this incident.

After seeing a smaller Kontronik Twist Motor opened, i was wondering if the bigger Fun 600 was built the same way. The twist motor had an insulation wrap around its windings which is not ideal to transfer heat to the can.

I always wondered what happened exactly to my Fun 600 motor and why it did "overheat" while only showing 70°C (158°F) at the heatsink.

The magnet is divided in 3 segments (still had a strong magnetic field so i didn't demagnetised the rotor -> my first theory). But look at the black marking on only one magnet segment.

One of the magnet segments came unglued and was not properly aligned anymore. On its last run one magnet rotated around the shaft.

The windings are wrapped with a yellowish foil and then placed inside the stator

I wasn't able to push the windings outside its stator. But have a look at how the windings of a Kontronik Twist motor are wrapped.

I think this is the reason why the magnet inside the motor came unglued. Heat builded up inside the windings. Heat could not be idealy transfered to the can. This is why i measured a much lower temperature on the outside of the motor.

My conclusion is: Those Fun 600 motors easely can push a 1:8 Buggy or a New Emaxx. But do run hot and can not be effectively cooled from the outside. In Heli forums those motors are known for their almost impossible way to be cooled. So if you run them properly geared in a not to heavy vehicle they will show good performace and heat built up will not get critical. But if you slightly overgear them or are planning to run them for a longer time, temperature built up inside the motor could become critical as their seems not to be an effective way to cool them from the outside.

Here are some comparision pictures between the Fun 600 and a Neu 1512

I now would always choose a Neu 1512 over a Fun 600 because temperature of the Neu windings is directly transfered via the stator to the motor can. So it makes sense to cool the motor from the outside (Fan, heat sink ...).

The Kontroniks are not that bad and I still believe they are better than the Feigaos. You should know that the Feigaos are heavily based on the Kontroniks more than the Hackers.

I once said that they are as good as the Lehners, but after what I've seen and heard, I proudly take back my words.

The Lehners and Neus are unlike any other. Hands down.

Hmm, they really do look like a feigao inside, but the Neu looks very much like the Hvmaxx motors inside. For the money too, the Neu wins hands down.

I just wish more people used the pletts- precious little experimenting done due to the high prices....
