Extreme RC's CNC Alloy 64-127mm Ducted Fans & Jet models discussion thread


This thread is for discussing setups for our Extreme RC ALLOY Fans & the new 127mm DYNAMAX & RAMTEC Fan setups & combos

First up the Alloy fans:Our 70, 90, 100 & 120mm units are available in various configurations right now with more exciting things to come in the large fan setups and our 64mm also in testing phase, hopefully ready by mid August.

Our housings are Taiwanese precision CNC machined & polished aircraft grade alloy units made for us by skyworld and come with a vented motor cover.

Included is a German made Dynamically balanced Wemotec GRP Rotor & shaft adapter set resulting in a superb high performance fan unit!

Also available in 70 & 90mm are our Extreme RC Schubeler Combos which feature Hand made DS31 or DS51 Carbon fibre rotors with our CNC Alloy housing set.

You can find the fans HERE All pricing is in AUD.


For those wanting a super hot 70mm fan setup take a look at the Extreme Alloy fan & ARC 2858 combo.
We have been running one of the new 70mm CNC Alloy Wemotec version fans with an ARC2858-1 on 6s3300mah 40c packs, this combo runs at 1900 watts and produces 57,000rpm for 2.5+kg static thrust and an efflux of 360kmh!!
EXTREME RC AUSTRALIA - Extreme ALLOY 70mm Fan with Efflux (1 min 18 sec)

Very careful balancing is required to maintain reliability but the wemotec rotor can handle 60K rpm comfortably.

For a super hot 90mm setup look no further than the Extreme Alloy fan and ARC 3665 or 3675 combos.
Running the 1 wind on 8 cells gets you well over 4kg of thrust with only battery performance affecting the exact power output.
Running the 1.5 wind on 12 cells is insane, I couldnt even get max measurements with my old scales but I have nice new 30kg scales here now and will be re-testing all the hot combos asap. Initial tests showed 44,500+rpm on the Midi at 3500 watts and I think there is more to come

Did I say it was groundbreaking??? Please keep your trolling to yourself, 5 posts and you are already reported in the other thread where you started attacking posters.

They are Skyworld housings. The stock 8 blade rotor will take 1200 watts before you balance it. The 7 blade 90mm rotors are actually very nice.
The stock rotors draw more amps, but the sound is great. We have no issues with the amp draw. I understand the new hoaye 6 blade rotor is more efficient.

I walk fine.. But I cant abide those who crow about how good they are and claim products as "theirs" when its just two products from differnet vendors jammed together..
Its not even OEM really, its just hack work..

As it says in the first post, they are skyworld housings, obviously no one bothers to read, too busy thinking of ways to bash the little guy down.

The skyworld 8 blade plastic coffee stirrer is not available from us so no point in talking about it or trying to push your own product in another sponsors thread, its just bad form Gary...

The Stock skyworld 90mm rotor is a Haoye rotor which I worked with almost 3 years ago when flyfly supplied them in all their kits, (ie topgun to you) and they are no different today than they were back then. I started the Midifan rotor swapout with flyfly kits, something which has been copied by many others since because its a better setup. A midi sounds great too when well set up, you only have to watch the numerous videos showing it in action.

I just purchased a JP-1000 (100mm) unit here in the states, and I'm waiting to receive it.
These look like very nice EDF's for the money.
What rotor comes standard in the 100mm?
What upgrades (if any) should I consider?
I'll be running it on 10s with a 45mm 1000kv inrunner.

The only rotors the factory has available for the 100 & 120mm housings is the Haoye one, while they can be balanced up and run I feel there is better to be had, until I get things under test conditions I wont make any wild claims...
