efflux RC...ALL ALLOY EDF unit
Here's a video of the 5th run up of our new, ALL ALLOY, 67mm EDF. (treat it like a 69-70mm........but with higher efflux)
The unit assembled very easily, and ran smooth as silk, out of the box with no adjustments.
The 3.17mm shaft adaptor is the collet style. There was no noticable runout or slippage what so ever.
We expected this unit to run at very high power levels, so we intalled a used ARC 28-58-1 motor, and ran it once on 4s, and 4 times on 6s. The test is running on 6s, 30c, 3200 mAh lipos, with a Castle, Phoenix 125 ESC.
There is a glitch in the trottle as it spools up. Don't know what that is yet, but it's ESC related. The ESC was progammed to Disable brake, and "soft cutoff". all other parameters were left at default. So, the timing was "normal". We expect about 200w more on "high timing" next time.
I have yet to attempt to read the thrust scale from the video. In an earlier test, as I did this alone. Yesterday, The thrust was 4lb, 5.6oz as read, and can be verified by Tim.
Since we only have this prototype unit. I haven't done a destructive test. But we ran it for long periods at up to 60975 RPM.
I won't compare the sound to anything, but it is truley awesome IMO.
This fan being 2-3mm smaller in FSA area. means that the efflux velocity should be higher than most, at the the same thrust level.
I'll hook up a pitot tube for efflux velocity measurement soon.
BTW. We are currently working with the AMA regarding the acceptance of this design.
Turn up the volume....and enjoy.

RE: efflux RC...ALL ALLOY EDF unit
the MAAA in australia has approved these and the EPF Moto range for use..
So they will be available through us in Australia..

To hell with the AMA they are an insurance company not a regulatory body.. What kind of engineering analysis was done on the rotor to make sure it is actually safe? What kind of amps are you pulling with the setup? A chart with amps, thrust and exit velocity would be nice..

RE: efflux RC...ALL ALLOY EDF unit
Wow that is putting out some high veolcity air. Looks like that may be the hot setup in the glass habu.. When will you have some available to sell? It is nice to see the top end, but It would be interesting to see a graph of everything over a range. 90 amps is a lot of current, what does it do down around 50 amps?

90A is not bad for a high powered 70mm EDF. You'd need to go to 10s to get the amps down to 50ish, but then you need a HV controller.
The fan is now in a 70mm, 4 1/2 Composite Viperjet. (still being built)
Our first small shipment is in US customs and will be here next week..
I'll post the Eagle tree graph soon.

RE: efflux RC...ALL ALLOY EDF unit
The All ALLOY EDFs are in stock. Not on the the website yet, but please PM or Email us if you'r interested. [email protected]
The SAPAC Viperjet is nearly completed and the ALL ALLOY EDF is installed with a 80% FSA thrust tube. At an AUW, the jet has better than 1:1 power/wt (with an 80% pipe)
The efflux velocity was 222 mph @ 100%FSA, and is estimated to be 240mph with the pipe.

RE: efflux RC...ALL ALLOY EDF unit
Its great to see what we can push fans to without real world constraints, but my concern is who wants to carry a 5000mah 6s pack in a 70mm model just to keep the 120 amps current draw under control.
Just my opinion butthe 87 amps that the wemotec rotor pulls to make 2.5kg sustained thrust ismuch moremanageable in the average 70mm model. I understandthere arethose who might want to carry small high C rate cells and do 3-4 second speed runs then fly around at 1/4 throttle but to me a jet is made to fly fast most of the time.
Something else I noticedis the voltage sag, these are the XPS4000mah 65c packs?the voltage is3.42 per cell looking at the figures,and peak load is 30c right? thats only half the cells rated C ability.Yousee higher voltage retention from 35c packs running at 22cwhich ismore than half their rated C ability. The new generations of cells are certainly performinggreat but not sure if I would call them 65c just yet...

RE: efflux RC...ALL ALLOY EDF unit
The packs used for the test were 4000's.... The point was to show the thrust capability of this Fan (I'm sure were not even close to it limits, even at that)
Folks are flying 5 and 6s packs in 70mm jets all the time now. Including 4000 and 5000, 6s packs in Habus.
We fly 5-6s in our 70mm composite SAPAC jets.
For those who don't wish to go to the extremes of this fans power. There's always our 5.5lb thrust efflux Pro 70 unit. It's still a 6s setup though.

So, it's not all that uncommon Mark.

I did say 5000 was imho necessary when dealing with 120A current levels unless you only want to fly WOT for a couple of seconds.
I have been running 5s and 6s setups in 70mm models for the last few years, they have their benefits which are usually based around higher voltage and lower amps, thus increasing efficiency
Iwould question whetherthe majority of 70mm jet flyers want to carry 6s5000mah packs, the Sapac models weigh in at 1.95kg with4s4400mah setupsand retracts.I haveset up the Viper at 2.25kg with 2.5kg of thrust and experienced the airframes severe dislike of the weight, end of the day it doesnt matter how much power youproduce to overcome the weight, the airframe hasnt grown
I am sure the Wemotec Minifan PRO rotoris also capable of more than the 2.7kg (5.94lb) peak I am seeingwhen running 6s, maybe I will try it

RE: efflux RC...ALL ALLOY EDF unit
It seems that the instigative posts by another Vendor were voluntarily removed by the mods. So my reference to them, and my replies were deleted by me.
We remain confident that our ALL ALLOY 70mm EDF is probably the most powerful 70 mm available today. (until I see conclusive test results, proving otherwise)
Only two days left at the PRE SALE price of $233.00

Just run the thing at 4-5s then, if your not a speed freak. This fan is for those want power. High voltage AND high amps means more speed.Look at thefast 12s, 120mm jets running 160A and bigger ESCs. Do you see them flying around on 85A?
If the amps are to high, for personal taste. run a lower kv motor and 8s.
Do be careful when you test that or any rotor near it's limits. Safety first.

I dont know what 120mm jets has to do with anything, I am sure the high amp onesdo fly around at 85A on half throttle though , I have yet to see many flying at WOT the entire flight
High voltage and high amps means more watts and one would 'hope' more speed, but chucking a pile of watts into something wont necessarily give you the best performance ratio either. 1870 watts for 2550 grams of thrust from one rotor (which had a thrust tube attached that raises amps) compared to 2680 watts for 2940 grams of thrust from this rotor(with open back) is to me a lot of watts for the increase in thrust...
OFCOURSEthere are guys out there who are happy with this (answering your next question) and I am NOTsaying its right or wrong. I am entitled to share my observations though.
So the interesting test would be to run some other popular 70mm fans up to 3kg thrust and see what it takes to do it dont you think? Everyone knows forme thats what its all about and what it has always been about, no need to peddle stuff, (or lecture me on safety but thanks anyway) test it and let everyone play with whatever turns them on!

do you offer a bundle for the unit w/ARC 28-58-1 with setup for out of the box running?
AMA guides for alloy fans? Anything yet?

The max amps will be ~119 with a 3150-3200 kv motor on 6s.
We will have the ALL Alloy fans that will accept 29mm motors in 3 weeks. That opens the possibilites up to Velocity and Neu motors.
I suggest only a quailty 3150-3220 kv motor for 4-6s max. a 3700kv motor for 4-5s max.
We will be specing an 8s motor shortly.
We can assemble theEDF with a motor of your choice for an additional $35.
Motor to ESC connections are not made, so you can choose where to mount your ESC. Some prefer to solder the connections. If you use ESC to motor connectors, I suggest 6mm bullets (not the springy type)
We had a pleasent meeting with Dave from the AMA safety committe at our shop 2 weeks ago. No word as to the approval yet.
