And where are the real motor diagnostics not unilog prop load data?

You never get that

REPORT!


Which gives and accurate account of things like total harmonic distortion and power factor.

Are there any readers here think that might be relevant in a REAL conversation about power system and not euro ces operatives simply trying to sell you overpriced crap?

HE GET EVERYTHING HES EARNED AND i WONT GO INTO CONVERSATION ABOUT PEOPLE "DNA" BECAUSE THATS REAL CLOSE TO THE EDGE! THE GERMAN WONT SIT HERE AND DOWN AMERICAN PRODUCTS OR OUR SAILORS IN IMPBA OR NAMBA AT 93% EFFICIENCY AND ILLEGAL HULLS

ALL LIES HES POSTED!!! WHATS TO BELEIVE IF YOU DONT BELIEVE THE MATHEMATICS IN HIS OWN CALULATIONS OF HIS OWN ENGINE
https://cimg1.ibsrv.net/gimg/www.rcu...a5efd44ee.jpeg

WHAT DOES IT SAY???

NO HE WONT COME INTO OUR FORUJMS BECAUSE FABIO BUZZI SENT HIM AND AUTOGRAPHED POST CARD THAT A THE OFFSHORE DIESELBOAT KING IS A BETTER U-1 DESIGNER THANM THE jONES FAMILY . THE EUROPEAN INVASION WONT FLY HERE.
https://cimg4.ibsrv.net/gimg/www.rcu...00117def4.jpeg

who cares? I dont and the Jones family is still the most prolific in U-1

And neither will a Russian lun hed think id build over a 3 wing Circus. Hes quite high if he believes that will ever happen. The lun is nothing but a russian interpretation of howard hughes spruce goose. THEY LEAD NOTHING HERE

HE TELLS YOU i LIE SO WHERE IS THIS DATA FROM HIM SINCE WE SEE HES ALREADY 3% LESS EFFICIENT??

Black Karma "POC" Edition
Total losses 74.6 ! https://cimg5.ibsrv.net/gimg/www.rcu...3912982b72.gif

Kt= 11.55m Nm/amp
Km = .1639 Nm/Sqrt watts
Power Density 59.88[Km²/g]
Maxon Eq 1.92 Max Eta 96%


WHERE IS IT????? YOU CANT SKIM IT ANYWHERE IN THE WORLD.

THESE ARE TECHNICAL PAGES SO WHERE IS THE TECHNIQUE THE AD HOMINEM HE STARTED AND SINCE THAT FROM HIM IS NOT REGULATED I FINISHED IT POINT BLANK

Yes if you have data to dispute it post it here!!! Opinions mean nothing in technical sections and i do care whats posted because it should be accurate for the readers or it isnt helpful;

and I know now 4 sure they are reporting to try to move the truth from the board.

https://cimg6.ibsrv.net/gimg/www.rcu...46151ee200.png

if im lying what is this?

or this

https://cimg3.ibsrv.net/gimg/www.rcu...bc9a9f948b.png

powercroco reports himself as 93.4% right here. this is HIS calculation. Nothings a lie or they would post the data

My breakdown of his power density is quite accurate to his own reports look again
Powercroco
Iron losses 280.9 wattshttps://cimg5.ibsrv.net/gimg/www.rcu...3912982b72.gif
Copper losses.3 watts https://cimg5.ibsrv.net/gimg/www.rcu...3912982b72.gif
Esc 7.2 watt https://cimg1.ibsrv.net/gimg/www.rcu...2dae124152.gif
The battery loses 2.4 watts https://cimg1.ibsrv.net/gimg/www.rcu...2dae124152.gif
His power density is 50.18 Km²/g
His Kt is 4.81 mNm/amp
Km .1552 Nm/sqrt watts
Maxon eq 1.92 Max Eta 93%


NOTE MY LOSS CALCULATIION ON HIS ENGINE AND HIS OWN

can ray charles see the EXACT same 280.9 watts there????????????????????????????????????????????? ???????????????

so if anyone believes them you know nothing about math or electronics so report it i do not care. Every bit of it is based off REALTIE MEASURED Contants....while running on the speed control

it cant get any more real than that!

LOL!!!

And so Steve sent a full cowl as well so Ill actually build 2 boats from this kit . The 3 wing and this 2 wing with MLBoatworks laser cut kit that someone is already inquiring about if I will sell the boat. Gotta have the salt Snorkel!

I plan to put 4 inch ralis in the CF shell with carbon fiber boon that run through the wings and certer section of the hulls to tie everything together.

BTW Steve Gualtieri will be releasing this scale fin soon

Hubert, Here's the link for carbon fiber.

A very interesting lesson.....

Did Fabio do that????

If the 41 series Lehner or 4225 scorpion is worth a flip then their editors will drop them in the calculators and telll you the expected performance with an actual boat propeller!


FE CALC
Showds In a performance hydro with 10s lipo @ 9800 mah and a castle 240. Prop wizard selected an ABC 1918 as the most efficient prop for the setup. Resultant: 28,221 rpm 141 amps 4,955.78 watts Pin 4,728.58 watts Pout run time 4.15 minutes est speed 79.20 mph or 127.46 Km/h Eff. 95.42%

Join Date: Mar 2016 https://www.helifreak.com/images/icons/icon1.gifHi Hubert,
thanks for offering all your know how . The 3d print stator are a real step vorward . i will speak about them with Albert from EOS. The have since so e years new micro 3d printer. They can laser sinter parts the sice of 5 micron.
I've talked to Albert a few times about sintering a few model components with the micro printer method, which instead of insulating material simply have micro gaps that are only kept at a distance with tiny spacer structures. This makes the components stable but insulated against eddy currents in the component itself. I need toroidal cores and a few rectangular components. A coil is wound on the toroidal core and the rectangular parts are exposed to alternating magnetic fields between two Helmholz coils and the heating is recorded over time. This can then be compared very well with all sorts of sheet metal components made from different materials.
You will certainly have a frequency generator to be able to carry out such measurements.
The copper wire bender has now rewound a 12 slot 4 pole motor and inserted the stator into the housing. The winding heads are now much too big and are also still very close to the housing components, which are made of aluminum. They are now properly heated by the alternating fields. Hacker motoren has been doing this for years . They copy the engines and tune them but don't understand that some rules of engine building are easy to follow. Anyone who builds such a beautiful engine heater does not exactly show know-how. It also makes more sense to use a motor that has been wound with multi-wire winding, for example, and therefore has fewer losses in partial-load operation. It can easily be selected with fewer turns because you can fly more energy-efficiently for the approaches or the ascent and then have more capacity in the batteries available and then at top speed flight can afford a higher performance.
We will see, when recalculating the maximum efficiency by no-load current by starting current square root of 1 - and everything squared gives the Lehner the highest efficiency compared to the Scorpion motors from Decker.

The boys have a right to the truth and accuracy that matter to their pockets and models performance. The forum is nothing without them! the petition TO SEE THE INFOMATION has over 100000 signatures.

Find you some props that make speed at 19000 rpm which isnt alot for a fast electrics.

DOCTORPROPS (torgg.com)

Id like to say something to any of the IMPBA body members here and Im not current on my dues. :p

Not trying to be funny but you guys not going to induct JA and AB into the IMPBA Hall of Fame???
