  • Hi Dr I did finally fing the weight of a HK 3226 on a superchief 5.1 from the other tuner that actually post his numbers with nothing to hide. Now the boys can surely can ger excited about my little power dwarf in a speedfire2 or similar hotliners or F3S speed planes After reading this data .

    Have a read Squawkers and enjoy the photos....


    "Hello Steve,
    you can rejoice, the 3226 with the 5:1 Superchief has even set a new record.
    I decided on the 5:1, because with the gearbox drive, the power comes more from the speed.
    As a 10 poler, it rotates a maximum of 49000U on the YGE, which it does without complaint, which is then 9800U, I don't need more than that accelerated with the GM18x22.




    I wound it with max. filling degree to 1160U/V and operate it on the modified Opto135 with 3x SLS 4s1800 2NOC.

    The 350g drive turns the GM18x22 with 8800U at 9.9kW 43V 230A on the test bench, and even with 80% efficiency at 88% speed stiffness, all measured with Unilog2, according to the speed calculator at least 12kg thrust.
    After 5x 3sec with a 20sec break, the gearbox has 50°, the motor 70° and the ESC 75, all without cooling air flow on the test bench.
    But the ESC gets a heat sink that is screwed tightly to the top of the fuselage so that the motor cables do not drag on the bell.

    So the 250g motor has an output of 40W/g and thus takes the lonely lead, it had already struck me very positively 8 years ago.
    However, it is already waving the white flag, the synclostprotection in the YGE has already mentioned so that it reduces the PWM to 99%.
    When the voltage drops and the load falls in the air, it quickly goes to 100%, so it's designed just right.
    Amazing that the 2NOC cells last at 48° before heated 125C with 3.5V/cell for 1-2sec, after that the load so the current decreases by 40% anyway.

    The gearbox still seems underchallenged, only the GM spinner is at its torque limit, the shaft flattening is counterproductive.
    If Christian's feet fall asleep, I still have the GM17x26, which is rotated at 9200U and should allow climbing over 100m/s.
    When the 2nd fuselage is there, everything will be installed, hope I can get in the fuselage with the engine cables, I'll get to just under 2kg so 5kW/kg.
    Then it's time to wait for good weather again."

    • 350 grams for the complete drive is what is stated. I guess that's why Dr Okon would not report it .​ So my drive according to the other tuners calculations does greater than 40W/g. So it doesn't lead US....

      My current 328.1 gram better cooled XNOVA 3226 geared drive complete here with spinner and prop on the scale in fact increases the already better power to weight ratio even if I use the Clugh rewound pyro 600 with the maxon gearbox versus the xnova. The maxon gearbox power handling is just as good as the super chief. The Pyro is the lightest of all three motors.

      Is this is why you are here but remain remotely silent about such things. You and your friends know 328 grams is pretty good if you weigh 350 grams and get thumbs up Ralph. I see your enigma, Thomas the tuner, reported the GM 17 X 26 on the 5:1 super chief can generate 360 km/h. That's interesting

      As well as the fact that his scorpion powered drive is actually 39.6 W/g based of his own data and the Clugh pyro power drive is well over 43.04 W/g.. So ill be dammed if Thomas's or your HK 3226 powered super chief drives are lonely out front. They are in the rear view mirror in America because not only is the motor and Maxon gear box 32 grams lighter with everything mounted, the lighter the pyro its self is 20 grams lighter than the HK and it is more efficient and makes more power. I guess you have to be mad at Thomas for reporting the rainbow drive weight and performance.

      • "According to my information, the relatively low price of these plates is due to the fact that not only are the labor costs lower there, but also the main components can be purchased there up to 50% cheaper.
        Since failure rates and reduced performance in Chinese components are now limited (and are probably getting smaller and smaller), this is quite economical for the manufacturers overall.

        The drone shown with the 2 rotors with the small concealed rotor heads probably only exists as a "paper" so far.

        My 12200 has been with me since yesterday - good, because a few days ago my last YGE "special" quit the service after many years. Btw. Like the 400 again in an idle test....."


        ~powercroco~

        Oh thats tragic



        And to be clear Dr Okon the 12200 $89.00 sequre will be the next piece of fine china that breaks on your bench. Common sense would have at least purchase the 14200 pro with 350 amperes of burst current and quality BEC for 103.00 dollars. It already has the more effective heatsink....

        it is 293 grams!!!!


        We also gone see how many good years of service you get with Xi'


        Even though I know you are going to get the smoke anyway. Good luck and please get some electrical safety training for higher voltages. I have no idea what the equivalent is there to NFPA 70 here in the united states.

                Betaflight Filtering 101 - Oscar Liang
                Betaflight Filtering 101

                What is RPM filter?

                Notchfilter sind hochwirksam bei der Rauschunterdrückung und führen zu einer geringeren Signalverzögerung im Vergleich zu Tiefpassfiltern bei gleichem Dämpfungsgrad. Mehr über Filter erfahren Sie in unserem Betaflight Filter 101-Kurs. Die Herausforderung besteht darin, die Spitzenfrequenz des Rauschens zu erfassen. Dynamische Filter können dies zwar relativ gut, erfassen aber nur eine Frequenz. Da die Motoren einer Drohne mit unterschiedlichen Drehzahlen (Umdrehungen pro Minute) rotieren können, erzeugen sie Rauschen mit unterschiedlichen Frequenzen. Der Drehzahlfilter von Betaflight ist ein leistungsstarkes Tool, mit dem der Flugcontroller Ihrer Drohne die Drehzahlen (U/min) Ihrer Motoren über bidirektionales DShot erfassen und eine Reihe von Notchfiltern genau auf diese Frequenz und deren Oberwellen einstellen kann. Diese Funktion hilft, Vibrationen durch Motoren und Propeller zu eliminieren und so die Flugleistung zu verbessern. Dynamischer Filter Seit Betaflight 3.1 gibt es jedoch die Option eines dynamischen Notchfilters namens „Dynamischer Filter“ im Reiter „Konfiguration“. Dieser hochwirksame Notch-Filter ist jetzt standardmäßig in Betaflight aktiviert. Er verfolgt die Motorgeräuschspitze und variiert die Frequenz entsprechend einer Echtzeit-FFT-Analyse. Diese Filter halten Rauschen in der Regel gut fern, wenn Sie die Filterparameter richtig einstellen. Es kann jedoch vorkommen, dass Schwingungen und Rauschen mit unerwarteter Frequenz auftreten, z. B. bei verbogenen Propellern oder verschleißenden Motoren. Hier kommt der dynamische Filter ins Spiel.

                Hallo Okon,
                Siehst du, wie offensichtlich es ist, dass du und die acht Piloten nicht wissen, was es mit Motorumrichtern und -steuerungen auf sich hat und wie man sie im Speedflying einsetzt? Du solltest mehr lernen, als du schreibst.​​

                  • Ralph,
                    Kristina braucht einen besseren Motor und ein besseres Tuning, um in Pink richtig gut auszusehen. Das bestätigt auch, dass sie so schnell nicht schneller fliegen wird. Wenn Piloten neuere, effizientere Wicklungen und Konstruktionstechniken nutzen wollen, werden sie diese in Deutschland wahrscheinlich nicht finden, denn du, Powercroco, bietet nur ungekapselte Stern- oder Dreieckmotoren mit Standard-Stahllagern an. Ihre Materialien stoßen an ihre Grenzen.

                    Siehst du, diese Motoren zerstören die YGEs auf deiner Werkbank! Sogar deinen speziellen „400“. Du wolltest deinen Freunden wahrscheinlich etwas beweisen, obwohl die Sicherheitsfunktionen deaktiviert waren. Haha, Marian von YGE hat dir gesagt, du sollst es NICHT tun. Du hast es trotzdem getan und den Rauch abbekommen…

                    Hab ich dir doch gesagt…​

                    Die Platinen sind so ROSA , dass nachträglich noch zusätzliche Stromschienen hinzugefügt werden müssen.

                        Ich sehe, du hast heute um 7:35 Uhr EST Unterricht. Pech für dich, denn ich bin heute nicht in der richtigen Stimmung. Aber mit der 4730-Patrone könnt ihr der HK-45-Serie sicher ernsthafte Konkurrenz machen. Ich weiß, dass du die Website von FRPower besucht hast.

                        Thomas hat seine Daten veröffentlicht, Ralph! Thomas hat seine Daten veröffentlicht, Ralph! Du und Lukey seid im Vergleich dazu nur noch Nebensache.​

                        • I think it's commendable that he is one of the few crocodile breeders to publish his data for every project. Regardless of his personal problems, he does a good job here. I've seen some of you question his data – that's legitimate. If you do that, you should also publish your own data and then remain silent. Criticizing someone just because you've never produced the 12N20P data or 14P rare earth magnets data. Static images without animation or data collection – that's ridiculous!

                          That's just trolling! You have reduced the discussion about engines to aesthetics and the color pink. You are making a big barrel out of this nonsense! This is just a diversionary tactic to cover up the fact that your ideas with the Sequre inverter from Hong Kong do not work and that you do not understand the potential of this system.

                          You're here now because you want to learn from POCBOI how to do it right. I know you have no idea about digital protocols and logic. I'm sure you don't know anything about Boolean algebra or how low-pass filters work with electrical RPM values and majority logic.

                          A newbie that does not have to worry because I'm going to feed you from both ends....

                            • "So I thought I should analyses the performance of some other candidate motors with the GF 5×4.5BN prop, to see how they compare to the RS2205S. For purely personal reasons, the motors I chose were the Cobra Champion CP2205 and BrotherHobby Tornado T1 2205. For all motors, including the Emax, I plotted data both for the mid-kV model and for the high-kV model in the range.



                              2205 motors with Gemfan 5×4.5BN prop

                              This was a bit unexpected, and most interesting. The CP2205-2500 beat all other contenders by a fair margin below about 730g thrust, which is about 60% throttle.The efficiency drops off significantly in the upper 40% of the throttle range, where its sibling the CP2205-2300 is the most efficient. It’s quite surprising that the low-kV motor is most efficient at high RPM, while the high-kV motor is most efficient at low RPM! Of course the CP2205-2500 does have a significant advantage in maximum thrust due to its higher kV rating, although this comes at the price of moderately high 27A current draw."

                              Its all old news (2017). Do you see where bruder hobby ranks in this test?


                              With that I have no more time today for this nonsense in Germany. I already told you 7 years ago an emaxx will easily out do the bruder hobby.


                              If you think i picked up the EIII emaxx arbitrarily to test beside the AOS you are sadly mistaken. It is already known through AOS's testing that the Emax out does it in total output. The AOS is less than 2 grams lighter. I have the bs here on the scale!!!! I picked the motor up because I already have a very good idea what it is capable of . The fact that emaxx manufactures about 90% of the drones motors produced world wide then there also that to consider. You may be running a "B" grade emaxx anyway....

                              • It should be interesting to see the results here because off the shelf it is IMO a noisy bi filar winding in the FRpower 4730 and that is probably why they would like to see what I can do with the engine to improve efficiency. Mechanically it looks like a solid roomy foundation to work with.

                                  Come on Dr Okon, why would you mislead your friend this way and why are you mislead? Firstly, you are connected as you are here every day several times throughout the day as "BOHO1" and are subscribed specifically to this thread. Secondly, Christian Lucas is not connected to me in any way and does not maintain anything with me, but instead a connection with you. I do not talk to him, do not need to, and he has not visited here under his profile in 3 or 4 months. The only one here daily for information out of America is you and your anonymous buddies here that would speak on it.... like so.

                                  What 777.77 euros is, is pure insanity for this pink scorpion nonsense and I pity the fool.

                                  You also don't know anything about the special process necessary to make the finalize connections to carbon fiber windings, Nor do you have a process for cryogenic cooling of high temperature superconductor. You are just blowing smoke up his A. All he can get is what he got.

                                  A parallel wye in copper, standard NMB bearings, and nothing at all to secure the wires. The grand wazoo should be more concerned about his telematics to an Eta of 68% and fried pink rotor. You will be the sole contributor to his e- fire and I will not have anything to do with it.

                                  • Das ist unglaublich! Ich baue den Cobra 5340 mit drei Lagern (Innendurchmesser 8 mm): zwei 16-mm-Lager und ein größeres 22-mm-Lager. Der Scorpion hat nur zwei. Die ABEC 7-Lager drehen sich 50 % schneller als die NMB-Lager, sind leichter und elektrisch von der Welle isoliert, während die Stahl-Lager dies nicht sind. Sie verwenden Shell AF2-Turbinenöl und sind für 61.000 U/min ausgelegt. Die NMB-Lager verwenden Hochgeschwindigkeitsfett, was zu deutlich höherem Rollwiderstand, höherem Leerlaufstrom und geringerer Effizienz führt. Die Upgrades und der Motor selbst haben mich nur 251 Dollar gekostet und sind insgesamt besser konstruiert als der Scorpion. Für 777 Euro kann ich drei 5340-Motoren ohne Kabel liefern. Der Cobra hat bereits eine höhere Effizienz als ein Standard-Scorpion, obwohl er kaum Kupfer verwendet. Ich würde Dr. Okon niemals 800 Dollar für diesen hässlichen Motor geben, der nicht besser läuft als Motoren, die nur ein Drittel kosten.

                                    Warum sollte man bei einem Hochleistungsflugzeug extra für etwas bezahlen, das die Flugleistung nicht verbessert? Das ist unglaublich dumm.

Die salzigen Krokodile sind ohnehin schon verrückt nach ihm…Beginnen Sie das Gespräch bitte damit, ihn zu bitten, Ihnen die Wicklungsstruktur auf der Rückseite und die Leistungsdaten seiner Hybridwicklung unter Volllast zu zeigen – Informationen, über die er Sie zuvor angelogen hat. Stattdessen redet er nur über die Farbe des Lacks, was Sie in ein peinliches Licht rückt, wenn Sie ihm zuhören, und lässt Sie am Flughafen wie ein Kind erscheinen, das mit den geschmolzenen Flugzeugrumpfresten herumspielt.

                                        Eine weitere Lüge des Arztes.


                                        Der 53-mm-Motor von Turnigy, den Sie gezeigt haben, ist ein absoluter Schrott. Er hat nichts mit dem Cobra 5340 zu tun, der effizienter ist als sowohl der Turnigy- als auch Ihr Scorpion-Motor. Außerdem verwenden Sie einen YGE 320-Regler, der ebenfalls nicht gerade modern ist und wahrscheinlich nicht besser ist als ein billiger Turnigy-Regler von HobbyKing.

                                        Das ist schon wieder eine Lüge von diesem „Experten“. Einen Drucker-Motor mit 0,2 mm Lamellenplatten gibt es nicht, daher ist die Behauptung, dass Wirkungsgrad und Zahnbreite gleich wären, einfach nur Quatsch. Außerdem hat der Scorpion sehr schwache Arme, er erreicht nur einen Wirkungsgrad von 68 % und kann sogar Feuer fangen – er ist also mit Sicherheit kein Spitzenprodukt. Selbst ein Blinder würde erkennen, dass die Geometrie völlig anders ist.


                                        Solche absurden Ideen zu verfolgen, wird Sie nur verlangsamen.


                                        Warum berichtet jemand, der hier im Forum nicht aktiv ist, plötzlich über eine Kobra in Deutschland?

                                        • Reden Sie nicht darüber, sondern senden Sie die Daten einfach an Ihren Scorpion.
