Anybody try one? 25 ounces of thrust from a 55mm fan, with an outrunner included, for $30 or so...

When I get one in for testing I will let you know what I think. So far I have been VERY impressed with the ELE motors

The only issue I have had with the high KV outrunners is: they are not compatible with the towerpro or Dynam ESCs

But I will have the ELE advanced series ESCs in for testing (they are compatible with high kv outrunners)

BTW look at the Temps of the motors...those are in DEG C which the one that is 94C is almost boiling

Seems like MUCHO thrust for very little moolah and size...40amps, but they have a 40a esc for super cheap...but what battery, is the question? And what will it do on three cells? I suppose the 25 ounces of thrust is on four cells, and four cells won't let you use the esc's BEC...

Will they work with the other ELE series, the cheaper ones?
The temp does not bother me...that's still probably a lower temp than a Cox Baby Bee!

No they will only work with the advanced series ESCs which are a little more $ but still a pretty good price. The issue is the timming..the high kv outrunners are "too fast" for a "cheap escs" and they get confused on startup causing sporadic jerky movements...I found that out testing the ELE460FX, but others report the same issue with the JGF450TH:
http://www.rcgroups.com/forums/showt...er+esc+problem



they do work with: CC, and Quark escs though...I tested with those and they work great

One thing you should consider (if you didn't know) the shipping from China can take a while. Even EMS can take while...my last EMS took over 2 weeks ...but I think it is just luck of the draw..it can be slow or "fast" depending....

Kevin at Elemodels is recommending their 60a Advance...wonder if that is overkill? I can use it in other models anyway, and the price is good...
I'm glad you said something, though, as I WAS going to use a Dynam ESC!

Kevin is a really nice guy

the 60 would be a good choice..that'll cover all the bases if you need it...If you can make it with a smaller get that later

I plan on carrying the ELE advance line in the future

Have had very good luck with EMS from China so far...
What is starting to concern me is this:
Fan and motor:71g
Battery: 189G
ESC: 55G

Total 11.25 ounces.
Not really appropriate for the 25" Babycat...
No free lunch, I guess. If I can go with a smaller batt and esc?

You might be able to shave some weight in the Batt/ESC dept

a lot of times the data they give is wrong....thats why I test em' myself...sometimes I get better results..sometimes they are worse...

Just what I was thinking. I will wait till you test them.
To get 25 ounces of thrust sounds good...to pay 12 ounces to get that...not so good!

BTW the 60A does NOT have a BEC..so you would have to account for that weight as well

Another option I've been playing with would be the ELE460FX I mounted it in a gws EDF55 and got REALLY nice thrust and only drew 17A!

Ino it isn't close to the "600W" setup ele has..but for a smaller app it might work great.

I would really like to get a different fan housing to test that motor in...any leads?

Wonder if it would fire up twins on a single 60A ESC? The CC25 fires 'em up pretty easily, with a bit of derating.

From what Darkside stated, it seems like an Advance 18 would work?

The25oz spec looks good, if its correct. GWS 55s give about 22.5oz with a Maxx 2025-5300, at more than 17A, probably closer to 25A.

A GWS EDF55 with a 5300Kv motor will pull alot more than 25 amps!!

I have run 5000Kv Hyperions in the EDF55, on 2s it pulls 17 amps for around 400 grams initial thrust, on 3s it pulls 35 amps!

The sweet spot for the EDF55 is around 3600Kv.

Darkside how did you fit that 460FX motor into a GWS EDF55?? Motor is 27.8mm diameter, EDF55 is 24.8mm diameter housing...

hehe I mangled the mount and used long bolts...also I bored out the hole on the impeller adapter...I was pulling 17A and thrust was GREAT


I really think the ELE460 would be great in a fan that it can fit in...

I'm really not impressed with the ele DF (by the looks of the specs) and for me to test it would be pointless IMHO

Well things have change :p

ELE is sending me the 5300kv EDF setup for testing I will post my results here, on RCH, and on RCG.

know that I do sell ELE products, so I might be biased JK
I no reason to manipulate any data as I wouldn't even have the EDF's instock

I did speak with ele in regards to the supplied outrunner: I do have the 2409 2900kv outrunner which is ok...I put a 5.7*3 APC on it and got decent power low temp,and low amps with it....Hopefully the outrunner supplied with the EDF is as good

I would like to see definitive thrust tests on a test stand, combined with volts, amps and RPM, this way we can see the efficiency of the motor aswell.

My hand wound 24mm Diameter outrunner pushes 430 grams thrust in the EDF55 at 17.5 amps and 10.5 volts. Thats alot of thrust from a fan housing with no eflux tube.

agreed..the specs on the ELE site do not mean much when the motor is at almost boiling temps

for the most part: edf's aren't really that efficient
