  • You are mad because there is now a safeguard in place from pure profiteers that overcharge the pilots for antiquated winding work with no extra$. The last thing a cheap greedy bastard wants to do is raise his marginal overhead. Talking about an Animal shelter but he wont donate your ass a better bearing for a motor that they charge you over 1000 euros for.

    You wont find a single Lehner or Scorpion at CK AERO but you will be able to find the Clugh Kontronik Growlers and Brenner contra drives there...

      • What the Americans will learn if they dig up the Lord/ IEEE data is

        No difficulties in vacuum filling were noted with CoolThermSC-320 encapsulant despite its viscosity being somewhathigher than those of the epoxy and varnish. In addition,the potting compound was effective at decreasing the hotspot temperatures even when the potting was not 100% dense. For example, the hot-spot temperature of motors potted with CoolTherm SC-320 encapsulant increased by only 3°C as the potting density was decreased from 80% to 50%, whereas the hot spot temperatures of epoxyand varnish-potted motors increased by 19°C and 25°C, respectively, as their potting densities were lowered from 80% to 50%.

        The Germans do not know what they are talking about. We went over alot of data to decide to do what we do.​ So these two should shut up because they use pure insulators in their engines that are not thermally conductive. They got all the hotspots and the wrong material selection to be experts on the subject matter. Their post let me know that haven't a clue about the actual research done on the subject matter.

        Their knowledge is general and antiquated on the subject matter. They do not update it because they think they know everything and don't bother to study the latest tech or research work.

        Ralph has not mention of the thrust stand at scorpion. He stays FAR AWAY from that.


        Why?

          UserHi,
          you only have to look at the windings cast by the American. Especially the winding heads have such thick casting on the windings that the heat is guaranteed to no longer reach the cooling air. It virtually traps the heat in the wire. The same in the stator grooves. Where air could pass through, he has placed his mush in a beautifully visible place. There is nothing that could dissipate the heat. So the coils are well insulated against cooling and exactly where the most heat collects.

          Question:
          How do you see them and how can he look at my end turns if he and you are not here clown number 1?

          His post again is clearly incorrect because a growler runs at an average of approx 5 kw and comes back in cool at < 60 C.in REAL LIFE....

          So you see he is a total buffoon. Where is this excessive amount in my winding heads? Its well wicked in between the wire and ties it nicely into the iron as a holistic cooling structure. You don't need air between the wires to help cool you need more copper if the space is there. Copper is the heatsink. It also wick in between the wire and the edges of the hammer. That makes me feel more comfortable about its insulation in critical short areas leaving my door step.

            There is no motor that loses as much in the winding heads as his 41 lmt. and of course Christian Lucas the motorfuhrer has all the answers about cooling and coils...

              • He is a funny little old man with nothing to do but troll and baby sit Miss dentistry when he cant produce the results he promises you with his 12N20P or Halbach nonsense. . Mike pulls a larger rotor and weighs less than his friends Alberts 4125 .powered Avant . Those are the facts. The losers in Dresden and Beyern cant do anything about it.

                  See he should worry about himself because the p850 weighs less and sinks his 4125 in power and power density as well. Ralph motor is also more power dense than Christians anyway. He gets mad when you report the calculations on his engine. Its not all that as you can see in the photo. look at the quality of his potting. It has zero thermal conductivity. Its also a sloppy inconsistent bead. His winding heads leave ALOT to be desired. All that copper is nothing but extra weight and loss. It is less power dense than the 4225 scorpion...

                  You look for yourself the quality of the bead and solder his machine lays....

                  watever!!!!

                  Please post more so i will be fully justified in reporting on you and the high quality manufacturing observed here....

                  • I guess he has forgotten Ralph and his friends FULL review of his 41 series wundermotors... You can read how that thread ends with him refusing to answer the questions asked ...

                    You can enjoy the review for yourselves. powercroco has alot to say about the LMT and its creator.

                    i dont have to even speak just go read it for yourselves all of it...

                    They just let him return from his banning there a few weeks ago.

                    2 clowns jealous of one another and every one else.... end of story!

                    They ruined all your technical sections with lies and advertisement of their products. Ive shown you directly how much the 2 men lie about just about everything.

                    Youve seen no 20 pole or halbach run but how many videos have I given you plus pilot review. You can waste your time with haters if you want to but you wont out perform us.

                    You can hate that all you would like. I think its funny and totally karma what has happened to your following.

                    Report the truth that the speeders nor the heli guys want the heavy ass engine in their vehicle. The outrunner has not broken a single record in boats while the scorpion owns a current. 2 lap in 2 classes .

                        "Mr. Okon has never noticed how to use such motorplates and high powerdens motors as he has no clue about motordesign. That he is allways following this tread by Hubert show his interest in Huberts coil design. That he say that it makes no sense is od and show how he is unable. Hey, let a Scorpion 4025 Motor that has a kv of 460 run at 35volt and 100 ampere = 3500 watt input power till it will reach 100 degree rotorbell temperature(need some minute) and Selead all the cooling holes , that is important to see the loss power and not how the cooling fan is working . In the same runtime a similar sized motor with the coils like Hubert wind his motor reach only 50 degree. This is a segnificant improvment of efficance for this coil arrangement. Hubert has done and it is cool."

                        powercroco likes this.​

                        You know its Christian's words for sure because he cant spell the English correctly in the direct quote from helifreak.

                        Ill also put it in German so the delusional friends in crocoworld get it too.

                        "Herr Okon hat nie bemerkt, wie man solche Motorplatten und Motoren mit hoher Leistungsdichte benutzt, da er keine Ahnung von Motorkonstruktion hat. Dass er ständig diesem Thread von Hubert folgt, zeigt sein Interesse an Huberts Spulenkonstruktion. Dass er sagt, dass es keinen Sinn ergibt, ist seltsam und zeigt seine Unfähigkeit. Hey, lassen Sie einen Scorpion 4025-Motor mit 460 kV bei 35 Volt und 100 Ampere = 3500 Watt Eingangsleistung laufen, bis er eine Rotorglockentemperatur von 100 Grad erreicht (dauert einige Minuten) und schließen Sie alle Kühllöcher. Das ist wichtig, um die Verlustleistung zu sehen und nicht, wie der Kühllüfter arbeitet. In der gleichen Laufzeit erreicht ein ähnlich großer Motor mit Spulen wie Huberts seinen Motor nur 50 Grad. Das ist eine deutliche Verbesserung der Effizienz für diese Spulenanordnung."

                        • Enjoy your spring break fellas and if you got a project for me just contact me. I don't have time to waste with these cats anymore. I have orders to fulfil . and r&d to complete. We do things differently here and no matter what they post that is what it is going to be. If anyone thinks they have proven me wrong based on what you have seen for their argument Solicit them freely. .

                          I know they haven't shown you enough to convince you of anything they have said as valid. .

                          I trust a smart hobbyist knows better because they can go look these things up for him or herself..

                              • Its so sad hat the poor man in Bayern with no electrical degree does not realize there are also cageless full compliment deep grove radial bearings. That's what really needed for highest speeds but since what we use is rated for 60,000 RPM and they barely see 30,000 were more than good. If he Knew Jim Allen like he claims he know how ignorant his post is.... The steel bearings ALSO have a cage that's heavier than the ceramics cage... so how does it cancel out?

                                What happens with a ceramic ball is eventually it eats into the stainless race because it its harder than the 52100 or 430 stainless steel.

                                He hasn't a single patent in ball bearing technology and he isn't much or a machinist either.

                                He is simply a jealous person. Ignorant as can be. When you look for input on the garbage he shows you he hits the ejector seat then comes back weeks later and injects himself into business he has nothing to do with while you are supposed to forget whatever bs proposal he suggested and never completed or proved to you with data for verification of an improvement.

                                He hasnt a single favorable review on his engine. Even his friend Tyler Garrard said you can buy a much cheaper TP power from Japan and get better efficiency in a boat.

                                • If a motor is 3500 wats but has a noisy AC with an idle current that generates 350 watts loss that's more than his calculated 7% Securing wires is also not just about thermal conductivity its also about reliability and consistency in the machine. A full steel bearing is also not electrically insulated at the shaft like ceramics would provide. As shown professional manufactures have already tested an verified the improvement it can bring. The guys is also clueless about lubrication as we have already covered lubrication options and the special process we use that utilizes space age dry lubrication if the pilot wants that Alot of the F3A guys use it for the gearboxes extended radial loads.

                                  Our Ultra Dry Lightning Lube process is available for all metal parts and eliminates the need for using any grease or oil. Bearings, gears, chains and more can now be run completely dry, no more mess! Ultra Dry Lightning Lube can be used with all greases, fuels and oils to extend the life even further. Most radial bearing sizes can be processed for $15 each, and insert bearings for $30 each (Cup & Cone type bearings will have to quoted according to size.) For all other components such as gears, valve components, camshafts, crankshafts, cylinder heads and any other engine parts call with specs for a quote. Most Go-Kart chains, depending on size and length, can be processed for approximately $30. Larger and longer chains will have to be quoted. Ultra Dry Lightning Lube LBT Dry Lube has been accepted and widely used in many industrial applications since the 1960's. UDL is a process that is done to bearings, not an actual product. We are able to UDL customer inventory, or inventory from our own stock. We are able to disassemble cross threaded roller bearings for the UDL process as well."

                                  • I'm going to rewrap and Egodrift 4035 for one of my scale boats. In return I'd love to see Christian Lucas's boats head to head in any arena with his 4125 LMT installed. Let me see if I can get my hand on his EGO buster for 200,00 dollars USD. Andrew Jesky flies Egodrift in his 3D plane so I may send him one for his VLV contra drive as he inquired about it some time ago.

                                    My NAMBA member number is 960.

                                    I also plan for him a Pyro P650 16 turn 17 AWG winding secured in epoxy with even better thermal conductivity than the 3M I've shared, Brenner, CK, Aero, and I have other materials that perform 4x to 5X better that I purposely do not share on these forums with team xerox.

                                    They really have no a clue about all the tricks we could use to outperform them. We do not share everything openly with them for obvious reasons.

                                    Thank you

                                    • Lucas hasnt a single favorable pilot or sailor review on his 41 series engine. Even his friend Tyler Garrard (Race Machanix) said you can buy a much cheaper TP power from Japan and get better efficiency in a boat.

                                      TP 4090-CM (1812KV, 8S)

                                      FACTS!!!

                                      On a gearbox for a speed plane they would make Ralph's 50HK's look sick as well. His motor is nothing but Hong Kong with alot of German hype!

                                        • One day, perhaps, it will turn out that the only thing special about the 41 LMT is the creators mouth. If you want, you can celebrate that day today. If the two lighter TDRs aren't enough for you in real life, just look at the models, such as the 4525 Tengu HT from Egodrift. It weighs 476 grams and achieves a peak power of 12 kW with a continuous power of 6.72 kW. It's lighter and easily making as much power as a 4125 LMT. So Albert Fruth can fly lighter with the same available power in his Avant.. with the simple motor swap.
