Right Ralph 10kw of INPUT power .......

you make sero sense #14 😀 as a 4235 weighs 519 grams without a prop or yoke. The Xnova drive with prop for a plane for which the 4235 wont fit is 328 grams with the prop mounted. It doesn't run as hot or draw as much mower as a scorpion to do its job. everyone knows pound for pound they are stronger. and everyone know the potential of the gearbox as compared. You running your mouth recklessly so were are back to the question of if your 50mm knocker can deliver the 4.31 Nm at 16000 rpm for 69 degrees Celsius and 92% efficiency??? Now the remote response stops!!!! Direct Drive.....

4.45kW is also the cots rating for a 4235 so it only 500 more watts capable than a power plant half its weight. I hear the 10 Kw claim from you so i guess i could claim apprx 9.5 for the pyro 600 especially through a gearbox that allow it run more freely. The HK is also 400.00 usd. The Xnova was 190.00 dollars. The Pyro 600 and 650 are also cheaper and lighter. The p650 tops a 4235 in performance as well.

Your post are hillarious. 10 Kw for 2 sec at a million degrees centigrade..... the trap is 10 seconds and so we see your results 👀

[Clugh]

Show off for the boys...your rainbow drive which is not as attractive 😂 is at 329 grams with no prop, pinion, spinner, or yoke.

You also forgot to mention that even the small HK 35 fell apart and scrubbed the bell at 44,000 rpm it only has 2 steel bearings and one is only supported by the stack!!!. So it cant really even do it😁This is a 3.7 planetary not a 4.1 so I wouldn't be winding for that Kv or rpm in the first place thus I have a higher Kt from the start into the gear box. I'm tired of calculating things for you. You need to figure it out to be competitive 14. The reason we run fully supported pyro carriers with 3 ceramic bearings and white lightning lubrication is to counteract increased radial load placed on the motor bearings when it is matched to a planetary gearbox dingleberry. The ceramic bearings are also lighter.

When you are ready you can put it with the prop and spinner mounted on the scale for your friends.... dont forget to tare it!

Da Sie alte YGEs verwenden, gibt es noch mehr zu beachten. Sie können 44.000 U/min auf dem 10-Pol nicht sehr gut erreichen und der Innenwiderstand und das Gewicht sind höher als bei allem, was ich verwende. In manchen Fällen fast doppelt so hoch. Von den 10 kW Eingangsleistung, die Sie behaupten, verlieren Sie mit dem höheren Einschaltwiderstand deutlich mehr durch den Wechselrichter. Mein APD schafft es bei 100.000 U/min. Sogar der kleine Leistungsschlumpf schafft es bei 75.000 U/min bei 64 kHz. Haben Sie noch mehr zu posten? Ich möchte Sie nur wissen lassen, dass die Sache mit der Fernbedienung wirklich seltsam ist, da Sie hier auf dieser Site sind ...

Since you are using old YGEs there is more to consider. You can't get 44,000 RPM on the 10 pole very well and the internal resistance and weight is higher than anything I use. Almost double in some cases. Of the 10kW input power you claim you are losing significantly more of it through the inverter with DOUBLE the on resistance which has half the power density. 😁 The APD manages high pole counts at > 100,000 RPM.



Even the little power smurf manages at 75,000 RPM on high poles and can at 64kHz. It is 3/10ths of a gram and peaks 2.25kW @ 6 s lipo for longer than 2 seconds...LOL! Do you have more to post there in Germany?

I Just want to let you know that the remote thing is still really weird since you are here on this site under my other alias...

[Clugh]

Here is even more the troop can observe. As is has already been stated we can mount the gearbox in a contra rotational configuration. There it can turn these 2 contras at 6000 rpm on 10s lipo. In direct drive do you think an HK4235 special edition can do it for 80 amperes? at 60*C after flying a 25P flight plan?

Also take note.... you cant even get a HKII4235 currently from scorpion...



Anyway there are empiric prop charts from scorpion lets take a look.....

An A series 4225 V2 which is what is available to hobbyist for 3d flight at 350 grams is already out it's range with ONE prop over 19 inches and double the pitch its recommended. There it only makes 3.6Kw

[Clugh]

Scorpion A-4225-500kv V2 - Scorpion Power System

Now you go here and you will find Ralphs power dwarf needs about 45 amperes to turn 1 Falcon 18 x 10 6200 rpm. So the answer is no it cannot in direct drive turn two 20 inch props counter rotationally with nearly 3 times the pitch to 6000 rpm efficiently.. Peak eta is only 83% with the motor already. It would be considerably worse trying to turn the 20 inch pitched props. Desynchronization or fire is what they would get and what he fights everyday. It is the song of Ralph's powercroco scorpions. All the needed repairs of his nuclear powered 10 kW motors are there on his pages. The LRK wye align stepped away from his power croco 4225 with +3% in Eta .

Chris, du siehst, Hannibal schweigt wieder wie die Lämmer auf dem GSM.

[Clugh]

Hi Christian,

He needs at least 5025 to keep up with the 328 gram geared power plant just to turn 1. The 5025 A series is 523 grams bare crisco....
Scorpion A-5025-215kv - Scorpion Power System. The troop would have to turn the recommended props a 20 x 10 Falcon at 12000 rpm to have the same pitch speed as the supernova 3.7 on 23 x 20 contras. but this isn't possible because the peak pull for a 5025 with a 20 x 10 falcon propellor is 7,762 rpm

Dr Okon is really bright and has it all figured out! His direct drive 5050 also has a lower Kt than 1/215 .



Thank you for your time and patience,
Hubert

[Clugh]

And so returns their proxy war amongst themselves and he is outta here...with a lesson from his friend about the gearbox power to weight and large prop advantage for air traction.....🙄


We are 14! and you must be because you camp here. I'm sure they really miss Bert and Holle's pyros 😊




later gator .....

Pull out the lego set.

[Clugh]

Morgen Ralph, ich sehe, du und dein kleiner Freund seid hier, um euch für den Unterricht anzumelden. Also lass mich euch das Problem mit euren HKs mit den 2 5-Dollar-Lagern zeigen, die ihr immer einbaut.



Im Vergleich dazu sind Ihre kleinen, leistungsstarken Maschinen schlecht konstruiert. Es ist eine Schande, dass Sie das Offensichtliche nicht erkennen.

Hi everyone!
After we have had good experiences with the 4:1 Superchief and HK3536 on the PC 11.5x44.5 four-blade in the Elysium with 580kmh at 9kW, the theoretical potential of the transmission drive up to 650kmh is now to be exhausted. The direct speed drives no longer seem to give this leap.

A real speeder was needed for this, because the strongly stretched surfaces of the Elysium have their structural limits above 600kmh. Also, the monster has the right size for the Superschief, the Typhoon has 50% more surface area and would need even more power, which would overwhelm the gearbox.

In addition, the power had to be increased from 9 to 14kW, since the monster is larger than the Elysium and is supposed to be a lot faster. This meant increasing the diameter to 11.7" and speed to 11000U, as well as from 12s to 16s so that the current for 14kW does not exceed 250A.

Since there are unfortunately no 3:1 gearboxes, the adapted HK3536 now had to turn with 44000U, which it did at first. But then he decided to mutate into a magnetic grinding machine after the long bell suddenly started to vibrate despite the 8mm motor shaft.

Unfortunately, the Opto 255 without housing could not handle this machine and turned the engine test bench including the kitchen into a shot-up village. Especially in the tabletop he left deep and lasting impressions, amazing what the energy from 16s Lipos can do.

In the longer mourning phase I had enough time to remove a good 2mm from the beech wood table top. Then everything didn't look so bad anymore and the project had to be continued with the search for a suitable engine, which succeeded without further losses.

The still unnamed motor gets along well with the new Opto 255 at 44000U so 11000U on the prop, and allows itself at 56V 250A so 14kW, even 270A were no problem. Since everything held for 1Ah on the test bench despite poor cooling, it should work safely at 600kmh cooling air.

For this purpose, the regulator heat sink was moved to the outside, as there are sauna conditions in the fuselage, and the spinner was transformed into a Swiss cheese. In addition, the gearbox got a heat sink that lies well in the air, I'm really amazed at what the gearbox can do with glued pinion.

When the new lighter and more stable surface in core construction comes soon, the bird will land at about 2.6kg, i.e. 90 wing loading, and have a power-to-weight ratio of over 5kW/kg. Hopefully, this should achieve the goal, I will report it...

[Clugh]

Ralph,
Did you note his little power system fell apart at 44,000 rpm?One HK3536 motor and YGE255 opto inverter destroyed or does no one the silly German site read clearly? He blew a YGE 255 with the power turd from HK in this stellar setup of his.


Looks like he drew more than 270 amperes in reality huh???????? The 255 peaks 400 amperes! and it isn't going to perform that well on 10 poles at 44,000 rpm

Replaced by an "UNNAMED" motor...

Auch in deinem letzten Beitrag liegst du falsch, Kritiker! Die Leute interessieren sich für die Vergangenheit, die den Grundstein für die Zukunft legt. Wir haben aus deinen Fehlern gelernt, aber du nicht. Das ist deine Schuld. 14. Da Erwin und die Wolfsbande wie alte Rennmaschinen sind, sieh dir diese hier von Ed Kalfus an und schau dann nach, wer er ist.

See there is plenty of interest in the past 14

[Clugh]

And BTW where are those photos of your geared drive weights ???? I am sure everyone is interested in that since you already posted the obsolete gear drives no one cares about from 2010.

I guess were in a hobby renaissance period.


Thank you
Hubert

[Clugh]

Certainly Its all funny. For one no hobbyist can purchase a new 3526 scorpion direct. A special order 3536 certainly makes more power than a 3526 but it is longer and it weighs 365 grams and peaks 4100 watts for 2 seconds. The Pyro 600 on a 7 to 1 planetary tops that everyday in 25P programs at 60C when its done.😀

The 3536 weighs more than the entire supernova 3.7 with prop and spinner mounted. You guys compare a lot of apples to oranges but in weight the equivalent direct drive outrunner is 4020 HKIV 329 grams. It peaks at 2.6kW off the shelf. Mechanically verified.

You and I both know it wont turn a 20 x 23 carbon fiber contra 6000 rpm on 10 s lipo direct drive. No one is interested in trying that with either of the scorpions in direct drive.
