The various and complete ducted fans:27,30,35,40,45,50,64,70mm !!!

Hi all,

Look at the attached pictures about the various and complete 8 or 7 blades rotors

We extended the range of ducted fans such as 27mm,35mm,45mm,50mm,70mm.

Except 27mm ducted fan comes with the 7 blades rotor,the other are 8 blades rotors.

The thrust is increased not less than 20% comparing to the old 6 blades rotor version. For example,ADF30,C10 13000kv,2S,thrust is about 140g.

We hope this will meet your needs

All the new ducted fans will be ok in 1-2 month:27mm(7 blades rotor),30mm,35mm,40mm,45mm,50mm,64mm,70mm.

New fan housing and spinner

Not only the 7 or 8 blades rotor but also the new fan housing and spinner make the ducted fans more powerful than before,the preliminary testing results shocked us . Not less than 20% thrust was increased !!!

New fan housing and spinner were designed according to aerodynamics and reducing the resistance and increasing the thrust furthest.Especially,there is a hole in the shore so that we can make the cables of motor across it.It can protect the cables from clash and rub.and,reduce the air resistance.

Are these push-on rotors or do they use adapters... if so, do you have adapters for all popular sizes of motor shafts.

Sigh............

Looks like a copy of the GWS housing. Even if it isn't - you still screwed up the design by using 3 stators. Fan housings need at least 4 or else you end up warping the housing when installed, and the fan rubs.

Are they balanced? If so I would love to try one.

Skyhawk, AEO cases are far more stronger than GWS cases. They are really hard to warp. The material used is much stronger. Using 3 stator vanes is exactly what you will need for the 8 blade rotors. The AEO motor mount is much more adaptable to various motors than the GWS cases (for the smaller sizes).

Great stuff Hu! I gotta try me one of those new 7 bladers! It looks like the hub is `12mm?

I can second that. While getting data on an earlier version 30mm/6 blade, I had to hold on to the DF unit very tightly. I was afraid it would jump out of my grasp, it was putting out over 100g thrust. I could not have done that with the GWS, the DF unit would have distorted.

If they're getting >20% more thrust and on 2S, that's awesome. I'd like to know if the amp draw is down over the earlier verson though. I'd like to be able to keep bat size down as much as possible. Small light planes, with relatively heavy bats, don't last long.

Wow, really cool! What motors are available for the 30mm? Just how much thrust can you get? Do you need to resort to ultra micro gear, ie like the Parkzone "brick", or can you use really small servos and mini 2.4GHz Rx's? How about an esc? I'd really love to make a stick and tissue type (like the old rubber scale models I used to make as a kid) super micro size jet to fly in my front yard.

Yea, with an even number of blades, you would need either 3 or 5 stators. HET 6904 uses 3. Works OK by me.

Hope these parts show up in the marketplace so we can order some, and find them in stock, on a regular basis.

Interesting Video here of the 30mm and a? c10? (hard to be sure but it's the right colour at least :-)

AEO 30 MM EDF 8000KV
2S 400MAH ESC 12A
http://v.youku.com/v_show/id_XMjI5NDA3MDE2.html
2S 800MAH ESC 12A
http://v.youku.com/v_show/id_XMjI5NDA2NjIw.html

Note the 50 and 60 gm thrusts :-)

Gotta love AEO's traditionally 'optimistic' claims, which in the not too distant past were acknowledged to be generated by blowing eflux onto a scale. Wonder If they've recently improved their methodology.

Bare, I couldn't read anything about the specs on the pages.

Where is it or can you cut-n-paste please?

Thanks,David.

Yes, you are right.Our cases are very strong and hard to warp.3 stator vanes desgin reduced the air resistance.And you can also make the motor cables through the tube in one of the stator vanes ,it can also reduced the air resistance and protect the cables from rub and shake during the flight.

Which hub is 12mm you said,David?

Bare,

Check out my video in the AEO 30mm 8000Kv thread (http://www.rcgroups.com/forums/showt...2#post17027219), it shows the actual readings for 3S from my Watts Up meter. I'll have to mount the DF unit in a plane to get thrust readings, but I could barely keep the little sucker in my hand during the run up. It's an early 6 Blade version. Short of having to press on the rotor, I'd say it's the real deal.

How many rpm's have you safely spun the 70mm to? I would hope it will hold together to at least 50,000, preferably 60,000.
IIRC most 70mm edf's spin in the mid to upper 40,000 rpm range.
