As far as Im concerned this man is the Outlier in Germany and he flies Neu, Castle, and APD!

PROVEN!

Besides you all want Talega while they are still viewing the daily winders news on Flying giants that hasn't been daily in over a month.

Here is something interesting. I call it the energy star wind. It is not all about winding factor but electrically clean standards. Dr Gerling has a work the emphasized low winding factors but ulta clean operation. I have tried to locate the paper over and over again but have not to date. I believe whole heartedly that I gave Skylar a link on rc groups years ago.

18N24P The winding factor is only .86 but shes devastatingly clean harmonically ITZ a simple ABC winding too. All coils are wound in the same direction.


Other peoples Trash has value!

Recycle!!!

In particular Id utilize it differently. This should make an excellent highspeed winding topology for a large outrunner.

If it didnt have torque its wouldnt be able to spin a full bucket of water wit wet towels in the washing machine it came out of. I got an SRM from one too. So they make plenty of torque.

At around 9 to 1o inches of diameter this should make and excellent paraglider or huge semiscale aircraft motor

Annealed Pyrolytic Graphite (APG), also known as Thermally Annealed Pyrolytic Graphite (TPG),[1] is a form of synthetic graphite that offers excellent in-plane thermal conductivity. As with pyrolytic carbon or pyrolytic graphite (PG), APG is also low in mass, is electrically conductive, and offers diamagnetic properties that allow it to levitate in magnetic fields.

Physical Properties

APG is an anisotropic material with extremely high in-plane thermal conductivity (1,700 W/m-K at room temperature [2]) and low through-thickness conductivity. Its laminate structure remains stable across a wide temperature range allowing it to be used in a variety of heat transfer applications. APG's conductivity generally increases as the temperature decreases, peaking at 2,800 W/m-K at approximately 150 K. Unlike pyrolytic graphite, the x-y planar conductivity is consistent across each basal plane, thus the conductivity in the center planes is consistent with the outer planes.[3] The in-plane covalently bonded carbon atoms in a hexagonal geometry account for APG's high in-plane thermal conductivity and its high in-plane stiffness. Through its thickness, these hexagonal planes are weakly bonded (van der Waals bonds) resulting in a material with poor through-thickness thermal conductivity, stiffness, and strength.

Synthesis

APG is produced in a process similar method to Highly Oriented Pyrolytic Graphite (HOPG), where hydrocarbon gas is heated until it breaks down into carbon. Pyrolytic graphite (PG) is then grown on plates using a chemical vapor deposition (CVD) process. The PG is then annealed at high temperature to form the more planar and more uniform carbon structure of APG, described above. The primary difference between the HOPG and APG synthesis methods is that the APG annealing process does not require the use of induced stresses, resulting in a more affordable and practical bulk material for production use.

Applications

APG is primarily used as a heat spreader for the thermal management of high-end electronics. Due to its poor mechanical properties APG is typically encapsulated within in structural metallic materials. Aluminum is the most commonly chosen encapsulant for its strength, low mass, cost, manufacturability, and thermal conductivity. Since APG's conductivity is much lower through its thickness, thermal vias are sometimes inserted into the assembly to transfer heat into the graphite, as shown in Figure 1. These vias are typically composed of aluminum or copper. Thin, flexible sheets of APG can be encapsulated in thin flexible materials, such as polymers, aluminum foil, or copper foil to create what is known as a Thermal Strap.[4]

Aerospace: Aluminum-APG plates are most commonly used as heat spreader plates to transfer heat away from high power density electronics in aircraft and spacecraft.[5][6]
Scientific Cameras: Cu-APG plates are used to cool and isothermalize CCD detectors at cryogenic temperatures.

Got my hands on it.

You don't have to spy I openly share what I find.. I also share the directions I move in versus doing the same old things.

Hubert

Default 12N10P Castle Creations 2028 Drag Motor.

I was looking at a 3040 Lehner but Christian never replied. So for now I chose another 60000 drag castle which would be1700Kv on 8 s lipo. The motor is 56 x 112 mm it weighs 1250 grams is sensored and has the stainless-steel sleeved rotor for high speed. It list for 365.00 but I only paid 300,00 usd for it. Im sure it would be outstanding in a huge speed plane on a p62 gearbox..

I may not use the engine at all but I want that option.. The pitch theory with the 1818 at 60000 would be 180 mph.
You can turn it with 10 s lipo and about 160 amperes to 30,000.

The one test id like to see with the slot less machine is ferrofluid in the air gap.. Ill have to buy the engine to see this tested. I know even on just the hollw shaft of a dc motor than it improved the magnetic circuit significantly improving the torque and thermal character of the machine by measurable amounts.

Life, The Universe, and Politics - FlyingGiants

They have an entire section of that Though " its not allowed" and nothing was political in the post so this is just more forum POLITICS right?

It was that post that made it impossible to post straight photos and it was un editable so all its points were going to hang for over 6 months.

All you have to do is send a few squirrels my way then and of course ill go over the top on points.

Wasn't that always the plan...with such an infraction.

Here was the post they made unreadable by anyone. You can see how blasphemous it is here...

"Moin Christian
Despite the fact there is no unity in America we still have some strong minds here that can actually produce something beyond a kit or plans. And so from your brother you know this already. You see they even have even tried to clone me...itz crazy ! Winding a 6 arm machine and accepting the result is so much simpler

It's fascinating but highly illogical.

Regard
Hubet"

That's not at all political so i just said forget it. It is not worth a battle or 6 months on a leash.... Whats so funny is Powercroco's" Ip address was also banned for trying his duplicate "boho" account of me there. Clearly him doing that also caused additional moderation confusion.

LOL

They know they miss the " daily winders news". It was an excellent show I'll really miss bringing it forth daily. It was alot of work.. It looks to still be doing quite well in syndication though.
Those damn squirrels were a trip...and got the job done didn't they.??



The E-motor forum which neither of them serve is perfect now.

But itz all okay. Michael always had the preparatory rebuff which is at @ 30,000 views now.
Thats like Mcdonalds numbers.
Over 100,000 served

Now Ralph is into Fast electric boats.

Its all good for rc sports

They will never again have an individual build a technical house on a topics and all things related with 100000 views in 1000 days. To me it has all the elements for the great drama it was. It had engineers, prodigies, and empiricist all in a never-ending battle about motor function that has spanned at least 10 years with just my chapters. And yes between all the nonsense there is alot of really great information people can use on understanding the motors and the windings. Everyone has their own set of credentials. It was a good thread. They ruined it. But that's just like real life. Nothing last forever. Especially antiquated winding techniques and the result they bring,
