Kontronik motors

[ChrisB]

The shaft just slipped on the retaining grub screws and the can partly came off inflight,looked bad in the heli but all stripped and rebuilt now and has been refitted and flown

if you running a Jive, then a pyro is the best match, (so they say)
been using them on my last two machines and getting very good flight times with the 700-52.
they run cooler than the scorpions and contrary to what Mr scorpion man said in the Rotors show, I think heat is wasted energy

+1, I have the same combination in my TDR and I'm amazed at the flight times and how both the ESC and motor are extremely cool when it comes down. I've recently order a second Pyro for my 570!

Everything on the Kontronik motor is made in house so the quality of it all can be controlled. All except the hardening of the shaft. The whole shebang

The design of the motor can also aids in better cooling than others as heat is off course lost energy. The copper used on the windings is a higher % copper base than others. There are many types of copper you can buy. The internal resistance is typically lower and even more so with the competition range. Effiency is unrivalled and I don't think you see ANY other brand quote their effieicny ratings. Most Kontroniks are greater than 90%. A few % difference here when you are talking of a 3.5kw and much more power motor is a lot in efficiency. Power is not everything, the 700 and the 4035 are still more powerful than a 120 engine and yet everyone raves about them

Also, run one of these motors for years and 100's and 100's of flights and it will still be as good.


Jez is correct, I have not run a different brand motor for a long time, I have always run Kontroniks 99% of the time after Gareth told me there was no comparing others even before any involvment. Oh wait, I had a 4535 in Spunky for a little while but then swapped it for a 750-50 Comp and the logs did not show much noticeable difference. Spikes where lower showing it was working not as hard but it is a bigger stator of course but other than that no drop in speed.

Other brands get hot not just because of the power as if you take 2 that are the same power output motors, Kontroniks will always be cooler. And to pick up on something Georges said on Rotors where he had a dig at them indirectly by saying about Kontronik always go on about industrial and professional quality, 50% of Kontroniks business is in industry beleive it or not so they have a wealth of knowledge here also and this is why reliability is so important and why they are so reliable.

Its like anything, quality comes at a price and you either go for it or you don't. You do not have to as every thing else out there will suffice but people like a choice and want a choice. Some spend the money, some don't can't justify it, can't afford it etc, whatever the reason but to dismiss something based on the wrong reasons is well, just that wrong For some reason we are power crazed at the moment with electric motors but there is no need to be.

People are still running the Pyro 30-12, which was replaced by the 700-52 and they are fine and without issue



Horses for courses, you might drive a ford or a BMW, take your pick but at the end of the day its great that there is such choice. Now, back to the Mostro and my JD

Ben, a quick question, if you need to replace a bearing or shaft, does the motor need to be posted back to Kontronik?

Ive got a 700-52 with bent shaft in the drawer for last 12 months, dont even think ben can get his hands on replacement shafts, back to kontronic I believe

Is it expensive to send back to get replaced?

[vinny155]

Not sure, ive got mine in a jiffy bag ready to go back for over a year, just have not got round to it

Yeah, they won't even sell the long shaft if you have the shorter shaft motor, they make you send it back (or at least this was the case last time I checked).

Yes this is unfortunately the case. You are not even 'allowed' to change your own bearings which I think is a little harsh, though I guess there are two sides to the story.... I guess that way they know that no one has been messing if they are going to repair crash damage for you e.t.c.

25euro + your postage cost last time i enquired

The problem I was having was my old scorpion was causing the powerjive to shutdown in hard collective moves. I re progged the jive in KSA mode 10 and flew again yesterday and pleased to say it was faultless so will hold onto the scorpion for a bit longer but I will try a pyro soon

Do you know what firmware you are running on your jive Milly? Curious as I have one on v9 and was looking at getting a scorp to run on it.
