NEW! BIG, powerful JetScreamer motor for 70mm fans - good to 1400 watts

[Littlescreamers]

4000 Kv (rpm/volt), 6 pole, weighs 5-3/4 oz., 5mm shaft, second motor shaft with end turned to 3.2mm included, 28.8mm dia. mounting flange, 33.75mm from face of mounting flange to face of motor, 35mm motor diameter. You love the small JetScreamer motor for its light weight and tremendous power, now you can have a new JetScreamer for bigger fans and higher power setups. Ideally suited for 70mm fans like the Wemotec Mini Fan 480 (WMF0013) or the 70mm fan that comes in the F5-E (ST105). The motor adapter is pre-installed and the O-ring provides a shock dampening perfect fit in most 70mm fans. The adapter positions the motor behind the fan, directly in the airstreams, providing great cooling that allows us to get tremendous power out of this motor. The screw mount spacing is 16mm and 19mm to fit most stock 70mm fans. Use with from 3-5 cells and from 44 to 90 amp controller.
1400 Watt OUTRUNNER Brushless Motor ..... $ 109.90

Scott :

How would this work spinning on the nose of one of my gliders running for about 5 seconds??? Any idea on current limitations for that time frame ??

Max RPM's id like to know also but I am guessing your in the 45K range..

Thanks

On a 2s and about a 10x8 folder - I see some SICK performance... :) I would be glad to TEST one for the common good.... ;)

[rvincent]

I have one on my Funjet with a 6x4 APC and have been radared at over 165!

[Air Head]

How many cells and amps for the 6x4 ??? Any ideas to start with for a 5 second run at around 100 amps..... I do not need a large prop, from what I have seen with my lightweight gliders, after I have over a 1 to one thrust to weight ratio, it seems that the smaller props with a higher pitch speed are better that more thrust at a lower on, just my observation..

I am thinking that I may need a better folding prop to take the rpm though..

Looking foreward to this one,

Rick

[rvincent]

You will need a carbon folder for sure! :eek: I have no idea what the rpm's are, but it sounds down right scary. I am using a TP3300 4S Extreme V2 and a PolyQuest 4350 4S and after 6 minutes I'm only puting 1800 back in to the packs. I am going to fly it Saturday with an Eagletree logger and see exactly what it's doing :D

[Air Head]

I am thinking about perhaps an 8 x 4 with 4 cells, think I can handle that ??

Rick

[rvincent]

You'll need a good esc ;) like a CCHV-110 :)

[Air Head]

Bob, Id like to see what the data logger shows you, I have been pushing mu motors about 140-150% for short bursts... Think I can go to 2000 Watts ??

[rvincent]

in short bursts, yeah :cool:

[rvincent]

Here's a Eagletree file from an EDF run. It shows 1531 watts and 48,000 rpms in a short run. It's just too messy to run it a long time static. Crap blowing all over the shop and the noise is deafening :D This was 4S 3300 with an HET 6904 fan.

Is there a drawing

--------------------------------------------------------------------------------

I am thinking about a gearbox for my glider application.. Is there a drawing for the front end of this thing??

Thanks

Rick

[rvincent]

Rick,
We would never post a factory drawing ;). It has the same mounting bolt pattern as all other motors in that size.

[Air Head]

I have a Scorpion 3032 that looks like it may be similar.. Is that one close ?? I can wait a few days to get it im my hands, then look for a gearbox.

That's rediculous Bob.
"Envelope" dimensional drawings are generally provided by mfgrs for commercially available components, to facilitate integrating the comonent into a design.

[rvincent]

No Gary it's not. Too many of our motors/designs have been copied ;) Then wind up competing against us as a cheap low performance copy! I have factory drawings, but on that page with the bolt pattern, is also dimensions I don't want out there.

[Ken Lapointe]

Is there a place where I can see a chart of the motor on the Mini Fan 480
with various battery line ups
2s = ? watts
3s = ? watts
4s = ? watts
5s = ? watts

thanks

Hi Ken,
Very soon. I do not have a Wemo Mini any more. I blew it up on initial testing :eek: But I can tell you that it will be about 1500 rpm higher and 4 amps lower than the HET 6904. And about 2500 rpm higher and 6 amps lower than the WM400. I will work to get this for you guys, but work has been really hectic for the last month and I truly have not had time. That and I still need a new Wemo 480, and a DS-30 to round out the popular fans for testing. Initially most wanted WM400 and HET 6904 numbers. For those we have lots of good info :) But Dennis is doing all these independently in the other thread :D

[Air Head]

From the photo it looked like I could un bolt the fan adapter....Well when I got the motor it was machined as one piece. I contacted Hobby Lobby and they said that the photo was of a prototype.. Also same photo at the start of this thread....also no 5mm shaft included as per the HL discription...

I was really excited about using this on a glider but sent it back for a refund...

Rick

[rvincent]

It is indeed all on piece ;) BUT it does have a 5mm shaft. The end is ground down to 3.17mm for Most EDF hubs....

The one you will want is the 90mm fan motor. It has no long motor extension and just a plain 5mm shaft. Contact me about that one Rick. I have one in my posession ;)

[Air Head]

Bob, these are getting bigger and bigger.....

Missed you at the LA Jets Sunday, I wanted to see you give the turbines a run for the money....

Rick

[rvincent]

It's the same size as this one exactly just lower Kv.

I was planning on being there, but got sick Friday night and spent all weekend flat!

[Air Head]

Hey Bob

I sent you a PM on the 28th and an e-mail on the 29th ......

Rick

[Air Head]

I give up, need to find another motor..
