    Schau dir deinen Freund in Bayern an, Dr. Okon. Er kannte Andrew nicht, bis ich ihm von ihm erzählte. Jetzt ist er voll dabei... Aber wo sind die deutschen Wunderkinder Dr. Okon 12N20P und 14Pole Halbach? Wir haben sie noch nicht einmal gesehen. Man sieht, wie frech die Redakteure sind. Er hat nach all dem, was er sagt, nicht die Würde, mir zu gratulieren Direkt.


    Danke

    • Jetzt können alle Ihre Freunde sehen, dass Christians 41 LMT und Dr. Okons Knocker bei diesem äußerst wettbewerbsintensiven und erfahrenen Piloten-Event nirgends zu finden sind.

      Sie haben Crocoworld jetzt etwas aus der Ferne zu berichten.

      Team USA is #1

      Ich lache laut.

      Tschüss.

        Hi boy,
        you have never show the 7 wind 1BOHO complete ? where is it ? and where was the engine measured by others who have nothing to do with you, such as Steve Neu?
        So everyone can simply write down a few data just to show a high level of efficiency.
        and who are we,“Since we lead in everyone.“ , the other Ralph Okon and Thomas Schmidt have already proven that they can wind top motors. But you haven't even installed a motor in a speed plane and none has run. and you pulled the data out of your fingers with a lot of imagination. So you're very far away from the leaders, rather at the very other end where it's called losers. Yes , also has an L at the beginning of the word . But we have a lot to laugh about you.
        Have you already seen Ralph Okon's new sheet metal cut, the one with the flux barriers in the cut for SPS winding?

        Happy Amps Christian

        • Is that so.....?

          Here are the facts.... Click image for larger version  Name:	shocked.gif Views:	0 Size:	542 Bytes ID:	430974

          Bryan Hebert is going to offer a motor in the spring that will be very similar to the motor that Bert was making. He is going to get Hugh to custom wind Kontronik Pyro 600 motors so they perform as well as, or better, than Bert’s motors. I flew one of these motors all through 2024. They are the real deal. The motor that I flew was the most efficient motor that I have ever run with my V4.

          The motor that Bryan is going to offer will have better quality, better reliability, and better performance than Bert’s motors for these reasons:

          1/.. Hugh is going to hand wind each motor with a custom winding to get the maximum amount of copper into each motor. This will maximize power and efficiency.
          2/.. Hugh is going to pot the windings with High Thermal Conductivity Potting Compound to increase heat transfer from the motor core, and prevent the wires in the winding from moving due to high magnet forces. This will prevent the winding from shorting out over time.
          3/.. Hugh is going to replace the bearings in the motor with hybrid ceramic bearings to make the motor robust to high motor rpm
          4/.. Hugh is going to have the bearings plated with Tungsten Disulfide Dry Lube, which will allow the bearings to run dry if the bearing grease dries up. This will extend the life of the motor bearings considerably.
          5/.. Bryan will also swap out the motor shaft with an extended shaft for use with a V4 Contra Drive.

          This motor should also be more robust to overheating:

          1/.. Hugh will use wire for the windings that has polyamide insulation rated for 250C continuous temperature.
          2/.. The magnets in the rotor will be rated for 150C​
          3/.. The Tungsten Disulfide Bearing Dry Lube is rated for 600C
          4/.. The aforementioned potting compound used for the windings will improve thermal conduction from the core of the winding into the air gap between the stator and the rotor. This potting compound will be rated for 200C.

          This will be a Contra V4 Motor that is able to deliver up to 3.8kW when used with 23” Falcon Contra Props. This is actually more power than is needed for F3A. The excess power is intended to be used in conjunction with a constant rpm D3 ESC to provide reserve power that the ESC can use to maintain constant speed through maneuvers

            • Based on the recorded constants the POCBOI wound 50 dollar swap meet motor had more power density that Dr Okon's 4225 or Christian 4125.which are both heavier machines.

              I have the 41 calculations as well Itrs power density is even less than Dr Okons buddy.. It makes a little more torque than 4225​ but its considerably heavier than the 4225​...

              I want you all to see.... They've known these numbers for quite some time and have been not even close to reporting the truth to you. but he is here to study what we do everyday.


              He won't give you recorded constants on his hybrid claims but look at all the information he has sucked up here from me.. When his freinds ask why isnt he doing it he tells them none of the things work, While continuing to inquire about the winding from a full forum that knows zero about it.



              Now I have things to do.

              You all have a wunderful day.

              • BTW....
                Andrew gave a small review some time ago...

                More testing news from Andrew Jesky. More good news for theorists...

                Hi Hugh,
                Andrew said the Clugh competition pyro 650 saves him about 350mAh per P25 flight over the stock 650 Kontronik motor. Andrew's P25 flights typically use about 3500mAh. That's almost a 10% increase in efficiency. Andrew is very happy with your motor. He says 350mAh is equivalent to two more maneuvers, which would give him a significant advantage in the finals. He also wants you to look at an Egodrift motor he has. I'll pick it up this weekend. Alternatively, he could send it to you directly.

                  • And btw Brenner the accomplished ME holds several patents

                    Now I really have to go to finish 2 more13 turn 650's for Mike Padrons TDR's. That makes 4 TDR's so far.. I have another 16 turn 650 to wind plus four 10 turn p600s. And I want them tested and out this week. I'm also on the grind for 12 hours while the kids play on their pc with no data.

                          ​Hi,
                          This MEZON 80 in the attachment probably what AJ is running . I say that because His Hui Yang Proteus bi plane he designed and stands with in the advertisement is what is installed. I'd actually like to get the inverters and a contra drive on a torque cradle. I do know from calculator databases that some of the inverters in the JETI Mezon class have some of the lowest on resistances in class. Very low voltage drop across these units. I need to grab one and a few other of the brands these pilots predominately run to facilitate further development of the F3A powerplants.

                          I'll ask Brenner after he is done flying. I think the NATS carry on thru till the 22nd.

                          Brenner and Jonathan Mowrey are hanging in there.....lets see with the final results will be.

                            • So for a 16 turn (8+8) YY in 17 AWG p650 is a minimum of 16.64mm^2 in the slot I would know I would need 28 turns in a DD for the same Kv. If one wants to run a parallel hybrid then you look at 19 or 20 AWG and you wrap 16 turns dd and 9 turns yy for a total of 26 turns and test it, If the Kv is higher thats good because you can reduce the turns and fit the 20 AWG. if you fit that you wont lose much in copper fill and you have the equivalent hybrid. You could also with a single serial hybrid wind and achieve similar results for the quieter running more efficient machine. There is also no reason a slot shielded 16 or 15 turn single layer wont easily compete with the conventional YY. You also get the higher Q inductance with more turns. The smaller diameter wire also rejects ac noise more so.

                              Lets see what it does before we listen to the inexperienced perps.

                              Der hier anwesende Doktor redet gerne, hat aber die Hälfte der Zeit keine Ahnung, wovon er spricht. Er kann seine Behauptungen über Hybride nicht mit Daten belegen. Die gesamte Branche weiß, dass sie funktionieren, aber er ist nicht in der Elektronikbranche tätig. Er ist nur ein Typ mit einer unumstrittenen und voreingenommenen Plattform, um seinen Unsinn vor acht Piloten zu verbreiten, die seine Segelflugzeuge fliegen. Es wurde noch größer, weil er einige Events mit etwa 20 Piloten organisierte. Er hielt sich damals für einen Experten für Elektronik, verfügt aber über keine Unterlagen, die seine Meinung zur Elektronik belegen, die sich auf die grundlegende Anwendung in seinen Flugzeugen beschränkt.

                                    • Hallo Ralph,
                                      Hast du noch etwas zum „American Super Motor“ zu sagen? Hast du schon Daten? Viele neue Mitglieder haben sich hier registriert, und viele sind misstrauisch, weil sie ihren Standort nicht angeben. Fast alle Mitglieder haben einen Standort. Das stört mich nicht, aber sei dir bewusst, dass es wahrscheinlich deine Freunde sind. Du solltest also dein Gesicht wahren, da du meine 22-poligen Stacks von Steve Neu erwähnt hast.

                                      Hast du Daten zu Steilpropellern mit 12.000 U/min? Diese Flugzeugmotoren sind sehr leicht und haben einen Flussring und eine Aluminiumglocke. Sie sind deutlich leichter als deine Scorpions. Die beiden größeren haben die Größe 4638. Was kann dein 4540 schwingen? Ich weiß, dass der 14-kW-Neu-Motor genauso viel Drehmoment erzeugt wie deine 20-kW-Maschine. Sie haben Rechteckwellenleistung. Die PS- und Drehmomentwerte stimmen gut überein.

                                      Ich bin sicher, all diese Leute würden gerne sehen, was du hast. Ich fahre für Weltmeister, genau wie du. Mein beruflicher Hintergrund liegt jedoch ausschließlich in der Elektronik.

                                      Hinterlasse deine Daten, damit ich deinen Freunden die Realität zeigen kann.

                                      Der Motor wiegt 446 Gramm.​

                                        • Wenn ein Idiot jemals eine Sinusschritt-Nachschlagetabelle erstellen würde, wüsste er, dass 100 % PWM nie wirklich existiert, aber er ist völlig ignorant und derselbe alte Lügner. Ich habe keine Zeit, mich mit Ralph Okons Inkompetenz auseinanderzusetzen.

                                          Sein mysteriöser Freund interessiert mich überhaupt nicht. Er ist offensichtlich auch nicht intelligent.​

                                          Die besten Piloten der Welt werben nicht um ihn.
