Alfa 5-bladed fan draws just a little more watts than the stock fan? (680 to 700W from above ... assuming that was on the Alfa?)

I was really expecting around mid-500's realistically. I'm glad I didn't just fire up the motor with my 40A ESC ... could've sent things up in smoke.

My 4S lipos just got here today ... man, these things weigh a bunch! I was planning to use them in my Alfa jets, but I'm not sure how I'll ever get them to balance out.

I thought the alfa 5-bladed fan drew less amps than the stock fan. The rotor and fan unit is a smidge smaller than the stock setup. At least when I tried it I was reading less IIRC.

That is what I would have figured, but you posted that you were doing 680W to 700W, and then that you were at 680W with the stock F-18 fan, so I just wanted to clarify for my own sake.

I'm still blown away they're generating that many watts on the Alfa fans with those Loong Max. I'd be inclined to think the motors would remain fine at those sort of numbers, too - after all, there are lots of folks using the Loong Max packs lately it seems, and I don't hear reports of Alfa planes blowing up and falling out of the sky all over the place.

I didnt take any hard measurements on the alfa fan, but I do remember it wasnt sucking up as much wattage. I cant remember the thrust differences, but at the time I thought I measured lower thrust numbers with the alfa fan, which is why I decided to go with the stock fan. Maybe on 4s it would be different. Don has some figures on his site for the wicked motor and alfa fan, and I would go by those numbers.

I will try to answer all the questions in on big post

I have carried the Pentium 60 ESCs only in smaller quantities. They have not been big sellers and they cost a lot more so I never really kept more than a few in stock at a time mainly due to customer requests. The real issue is that I can not beat Hobbycities price of $42.90 on them. And I got tired of the "I can buy it from HobbyCity for less than you sell them. " emails. The Turnigy is the same as the Pentium which is the same as the Thunder Power, they are very good ESCs.

Motor for GWS G-38:
The only motor I have for a GWS warbird is this motor:
http://donsrc.com/cart/index.php?act...d&productId=40
That is what I had installed in mine, but I used by mistake non foam safe spray paint and melted the plane so I ditched the project

UBECS:
I do carry a 3 amp swithcing UBEC.
http://donsrc.com/cart/index.php?act=viewCat&catId=6

As far as bigger motors for larger fans: I have no real plans on going bigger. I had planned on stopping at the 500-600 watt range as once you start going bigger the ESC are more $$$ then lipos are more $$$ etc. My goal has always been a good performance on a budget. I do have a GWS EDF-75 fan I am going to test on the Wicked EDF 4000 motor though.

Hope I covered it all!!

Thanks for that info, Don. Have you ever tried or gotten any reports on Suppo ESC's with your motors? Almost all of my ESC's are Suppo's, but I have yet to get to installing the power systems in any of my EDF's yet to test them out. The Executive Jet will probably get first treatment.

Don, I am very interested in the results from the GWS-75 tests. If they fair well in that unit they should be ok in a 70mm unit. I would even be inclinded to give it a try in a new version of the 75 unit.

I have never tried the SUppo ESCs. So far I have had no ESC compatabilty issues. You just want the timing to be set to LOW on any ESC. Some of the lower cost ESCs may not have a high enough pole-rpm count. The Pentium series has a 420,000 pole-rpm count. Since the Wicked motors are 6 poles, then can run safely to 70,000 rpm on the Pentium ESCs. But some of the lower cost ones have a lower limit and the motor may outrun the ESC near full throttle.

I will post GWS EDF75 results as soon as the 4000KV motors arrive. They are on the way via EMS and I have been tracking them so will be here probably Tuesday.

Well the Wicked Cool Winds arrived today and did some testing in the GWS EDF75, SF fan on 4S and the EDO fan on 4S (the fan inthe Hobby Lobby F-18, Mirage, and the Raidentech F-15).

I am transferring the Eagletree plots from my lapop now.

Don does the Wicked Cool have a 3mm shaft or 3.17? Numbers look good on the GWS-75.

Well as received they have a 3mm shaft that steps down to 2.3mm so they drop into the SF fan collets. So I swapped the shaft out for a 3mm shaft. I will add that option to the website as an option when ordering.

Cool, looks like that 4000kV motor will work well on 4s and the Edo fan!

Don, is this the motor you would recommend for an Edo F-15 upgrade? I am looking at getting one and want to put the right motor in it. Not sure if the model will take 4s without hogging it out too much, I thought you had one and would know better. I suppose if I stick with 3s I could go to a wicked extreme with the stock fan.

Are those graphs with your TP batteries, or your Loong Max?

Looks like the cool winds would be a really nice 4S replacement for the HL F-18, rather than worrying about the heat in the regular Wicked wicked motor and 4S on that fan.

Do you happen to know how the the 4000Kv does on the EDO fan with 3S? I'm curious how it would compare to the stock setup on the F-18, since I seem to recall that the 4800Kv was just a bit better than stock on 3S (but of course, you can't do 4S with stock, which is where the upgrade really kicks it into gear ... I still haven't finished any of my EDF's to a flyable state, and I've already outgrown 3S speeds within the realms of my mind and dreams ... hehe).

Here are the Eagletree plots for the EDO 5 blade fan. I used Long Max lipos on all these test.

EDO on 3S Wicked Cool Wind 4000KV
EDO on 4S Wicked Cool Wind 4000KV
EDO on 3S Wicked 4800KV
EDO on 3S Wicked Extreme 5400 KV

For a 3S upgrade I would use the 4800. For 4S I would use the 4000KV. The Extreme on 3S is good power too but sucks alot of amps, so will drain a 3S2200 pretty quick. By the way I am getting a spacer made that will drop into the EDO rotor and make it so you can not press it on too far.

Cool, thanks for taking that data Don! I may stick with the 4800kV on the EDO 5 blade for now. Looks like it gives a nice power boost over stock.

I am wondering - do you know if the EDO F-15 is easily upgraded to hold a 4s pack?

Ok Don another quick question. Have you done any testing with the Wicked Cool in say a Wemo MF480 or any other 70mm fans? Would be interesting to know seeing as it pulls under 40A in the GWS 75. Granted the GWS probably isn't as aggressively pitched as say a MF480 or HET 6904.

Thanks for all those graphs, Don! Looks like I'm going to be getting myself another of the 4000Kv motors for my F-18, and maybe I'll order up a regular 4800Kv Wicked and Wicked Extreme while I'm at it for this Alfa Mig (5-blade alfa rotor) and Phase3 F-16 (stock fan ... think someone said it's a 3-blade XF fan?) I have sitting around. How long do you expect until you get those EDO rotor spacers in for the 4000Kv, and the Wicked Extremes in? I'll wait until it's all in stock so I can consolidate the order and make things easy. I tend to forget what all is on it's way in to me when I start putting multiple orders in all over the place.

I wondered why the 4000Kv's were so much cheaper than the 4800's when I ordered two of your first batch for my Executive Jet, too ... now I see that ordering without the adapter/plug makes a pretty big difference. Comes out to the same price as all the other Wicked's when you add on the adapter option, which makes sense (though without the adapter, it's still a good bit cheaper than the other Wicked's without their Alfa adapters).

Looking at those graphs, I don't think I can keep myself from going 4S on the F-18. Two more amps of current drawn for an extra 166W of power ... hard to argue against that upgrade, that's for sure!

I have no idea what the pole-rpm count on these Suppo ESC's are, so I'm going to have to write Dave @ LightFlightRC and see if he can tell me. What happens if your motor outruns your ESC?

The 20, 30, and 40A Suppo ESC's only have basic programming options available (voltage cut-off and brake), but the 50A through 80A have quite a bit more options. Here's the list: http://www.lightflightrc.com/manuals/SP_50A-60A-80A.pdf

What would you recommend setting each of those at for your EDF motors? (in particular, the throttle range and PWM settings ... you already said to set the timing as low as possible, though I'm curious why that is since there is a 2-4 pole option and then a 6-8 pole option, as well).

I got some today, just need to check them out to make sure they fit.

I think there is a terminology mix up. There is the motor, the standoff adapter, and the Alfa rotor plug. The Alfa plug is just the little cylindrical plug on the end of the shaft. If you were to mount the 4800 motor into an XF fan you still need the standoff adapter but no alfa rotor plug.

Basically it will start to stutter when the limit is reached. It can smoke either the motor or ESC if the amp pulses get high enough.

The timing is set to "low" as most ESC companies never really thought of outrunners spinning such High RPMS. Generally what I have found is that higher timing gets the same RPM but sucks more amps. I would just use auto throttle range as well.

Forgot to say set PWM to 8kHz. The Pentium ESC I sell are all 8kHz.

Cool video! Mine behaves the same way with Don's motor on 4s.

With the stock motor and 3s launching gave me an uncomfortable pucker factor. I love launching it now since it just goes up in the air on 4s!
