JP CNC ALL METAL HIGH END QUALITY 90mm EDF 12S Testing video 1

High Grade All CNC metal 90mm EDF. Totally weigh is 464g(Include Motor).

5,5 Kg continual, good result. Last weight battery on 3S is 104g and discharge 70C /100A. (from nanotechnology) Its together 416g battery + 464g engine - 5500 = clear thrust is 4,6 Kg. Very good results. Dr. Liptakov

Will this work as fan for staircase pressurization in building in case of fire and what’s mass flow rate in m3/h? If it creates high velocity for propulsion can it also pressurize stairwell in case of fire?

[@chebertjr]

A 12S Lipo is just a little to big to put in a Stinger 90, that's why a 10S unit is and would be perfect, I have proved that in mine, an 8S would be fine to, if it only put out more thrust.

[@franciskrueger7717]

I saw a video 6.5 thrust at 10s fms

[@speedyzockt1912]

Hi i know this Video ist old but can Somebody Tell me where i can get all the parts (Turbine,battery and Speed Kontroller

[@chebertjr]

Shane are you planning on coming out with some hot high performance 90mm 10S and 80mm 8S edf units anytime soon, the hot 90mm unit I have pulls around 150amps and my hot high performance 80mm 8S edf unit pull around 130amp.

[@Arrobosys]

How much time it can work with full speed at one charge of battey

[@chebertjr]

What does the esc setting need to be set at to get the most out of this unit?

[@Jdspitz2]

What is the name of the song in the first 29 seconds of the video?

[@choppadoc3988]

I know this is old but what's the motor's rated continuous watts and amps on 12S?

[@shaneyang3869]

12S 46.8V 109A 5.69kg 5101.2W 459g(weight) 1080kv

[@choppadoc3988]

Those numbers are for continuous use and not 5 second max, correct? I just ordered one and want to be sure.

[@shaneyang3869]

Yes! But your battery have to be the high quality one. It is mean the fan able to out put that thrust for long time if your battery could offer that voltage and current.

[@chebertjr]

Why don't you do a video test on the 10S 90mm edf unit and all of the others without a wall right behind it?

[@johnnyj540]

+RC REVIEWER What difference does it make it there is a wall behind it:

[@shaneyang3869]

+Johnny “Exacto” J Nothing difference between them. The test stand press by EDF directly.

[@fern6978]

How many amps?

[@shaneyang3869]

109A

[@chebertjr]

I noticed in your test videos, you have your test stand close to a wall, this will cause inaccurate reading, you should be at least 10 to 15 feet from anything behind the edf unit to get s true reading.

[@shaneyang3869]

RC REVIEWER We did many tested as your suggest(10 to 15 feet or more). the thrust not have much difference between the videos. but the good battery and bad battery really bring difference thrust.

[@chebertjr]

Oh ok, I agree the battery will make a big difference.

[@chebertjr]

Shane when will the 90mm 10S and 12S edf unit be available?

[@shaneyang3869]

+RC REVIEWER Hi Clarence,The video is available now. Sorry to keep you waiting. Here is the video link: kzbin.info/www/bejne/nYiYnJt4jLyifJo

[@Ryzler13]

Deflection wall behind motor changes results. What batteries are you using and what is the amp draw at full current/throttle? Would you be interested in a gearing system I want to build? I dont really have tools to do it though.

[@shaneyang3869]

Nothing about the wall. The max current is 118A.

[@Ryzler13]

Shane Yang Well depending on how close it is. If you have deflection wall behind it then there is increased pressure and you will get false reading. How about the batteries? What brand and specs are those? Thanks.

[@shaneyang3869]

The wall is 0.5 meter away from the fan.

[@shaneyang3869]

Ryad Arlan The thrust is not from the wind which push the wall then show at the monitor. That thrust is from air pressure between air input and air output. So the wall behind will reduce thrust not increase exactly. The thrust also is difference between the fan have intake ring(more thrust) and haven't have intake ring(less thrust). Or you can try to close the output of the fan.you will notice the fan is zero thrust not to be the top thrust. About the batteries is comment brand in China, The ESC is JP HV 120A.

[@Ryzler13]

QUOTE - "So the wall behind will reduce thrust not increase exactly" If you put that deflection/wall closer to exhaust/output then there will be increase in thrust reading. Try it you will see. Yes if you close the exhaust nozzle there will be less airflow unless increase in power. (This is a single fan electric.) I am sure a variable nozzle will result in straining the motor. With a typical Jet the airflow through exhaust will increase as well as thrust but the intake will remain the same. QUOTE - "The wall is 0.5 meter away from the fan." What is the "Jet blast" distance? This will effect the engine as it has something to push against. Increased pressure behind engine. More "thicker/denser" air to push against. goo.gl/AlppKl I would love to share some ideas but I am saving anything relevant for exchange in person.
