I hear that.

$150 is good in between price point, if it is better quality that the feigaos.

It is better, that's for sure. I have the FUN480-42 and when I used it in my already sold B4 with 10 cells it made the car go CRAZY, and for my amazement, the motor did not feel hot at all. When I'll start my 1/8 brushless buggy, I guess I'm gonna get the 600-17 with two 3s 4900mah FlightPower and have some party!!! I don't know how well do they stand against the Lehners, though.

What threw me off on the Kontroniks motors was that the 600-17 is closer to 1600kv and the 600-18 is closer to 1800kv, so the label are misleading.

There is actually 200kv difference between the 17 and 18. I just don't know if the 18 is worth the extra $50. This might not make sense to some, but at $150, I'd jump on a Kontronik. At $200 for the 600-18, I'd be willing to pay the extra for a Lehner or Neu.

I am really tempted to get the 600-17, but I think that it will be more of a 5S motor than a 4S motor, which is what I'm looking for.

Captain, have you run a 600-17 on 4S?

I've never owned a 600 series befor. Sorry that I couldn't give a satisfying answer...:)

I haven' read through this whole thread, so my question is do they use segmented rotors? These things look like a pretty good motor, just in between the Feigao's and Lehner/Neu's. At least price wise.

Yeah, they seem like segmented rotors.

Also, make note that the claim that these motors can tolerate up to 300F needs a very simple clarification: the internal heat is much higher than the external( when touching the can), so I got a message from Mike Franz of Kontronik saying that the motor can tolerate heat up to 150ْC internally and 100ْC externally. It seems that the heat tolerance is pretty similar to the other motors.

Kinda what i figured on the temp handling.

I agree, the rotor is always going to be hotter as well, IMO.

I actually ran my FUN600-15 with 36 volts and it lasted longer than I thought. The motor is really good and I do have a FUN600-17, but I'll save that motor for something else. Great motors I have to say.

How do they compare to the Lehners, BTW?

Or how do they compare to Fiegao?

Yeah, this one too.:)
