The newest testing data for AEO 30mm ducted fan.


ADF30-100:

Motor:ADH100 9040kv

Testing datas:

7.0V 8.8A 76g thrust 53160rpm
7.4V 9.6A 84g thrust 55400rpm
8.0V 10.8A 96g thrust 59280rpm
8.4V 11.6A 104g thrust 61300rpm
9.0V 12.6A 116g thrust 64900rpm
9.5V 13.4A 124g thrust 63700rpm
10V 14.5A 134g thrust 70000rpm
10.5V 15.4A 144g thrust 72000rpm
11.1V 17A 156g thrust 75500rpm
12.6V 24A 170g thrust 78000rpm

The motor is on debugging,the thrust on 2S will be continued to increase.
I think it will be ready to the market next month.

Mmmmmm! Can't wait to order 2 of these...I have bought from AMA the plans of David Ramsey Boeing 727.It will be the perfect fan for that plane,because I can make the engines nacelles to look scale.Maybe 3 ,for increase a little bit thrust

Oh ya, that would be awesome!

Although, if you ran 3 on 2s, you'd draw 28.8amps. For decent flight times you'd want to run an 1800 to 2100. That's getting kinda heavy, plus your only looking at 8.8oz of thrust wide open.

I agree. Give the addition of a No. 2 (3rd) engine some additional thought. The addition would require a "S Duct". The added complication of this duct, as efficient as it could be made, is a drawback considering the added weight (EDF unit, battery weight and ESC) and the effect on the wing loading.

Looks like the thrust of this fan operating on a 2S battery will give the same thrust as the stock brushed GWS-EDF-50, however the Amp load is doubled.

When considering a small scale like nacelle, keep in mind the FSA as the tail duct exit diameter may need to be around 90%. I was able to reduce the tail duct exit diameter for the brushed motor and gain thrust while only a bit more Amp draw, but not for the Feigao brushless motor. I found that reducing the duct exit diameter for brushless increased the Amp draw without improving thrust.

At a 13oz flying weight with 6oz of thrust, the 727 will cruise at 1/2 power. I feel she won't mind a bit more (2oz) weight along with more power to cruise. She'll just fly faster.

You're welcome.

Be happy to help out during the build, which includes cussing me out for the some what delicate construction. Flys pretty nice.

For a local dealer, we will be carrying these motors as well as other fans from AEORC.

At 0.56 to 1.23g/W... you are not getting much bang for your buck... and with maximum thrust 170g... how much does the 4s pack capable of delivering 24A weigh!

Must be mighty good bearings to cope with 78,000rpm... 300W thru a tiny motor...and with a push-on cheap plastic impeller too.

Thanks again.The "little" 727 will be a winter project.In fact it will be a "bigger brother" wich will be made.Slow progress,because of making CAD plans,and I'm not a master in design.At 3 meters w/s,it's a lot of work.But the little one,made after your plans,will calm-down my dream about flying this beauty (by the way,I dreamed to fly a 727 in my life,wasn't possible because Romanian fleet never owned this type)

I'm not to crazy about the amps vs. thrust.

I envy your CAD ability, especially for changes. I can certainly dream of a little left or right seat time, once around the pattern.

I don't think it is a screw. If it is similar to the 30mm 12500KV fans we have, that is a cooling hole.

Wouldn't a cooling hole need an exit ? That KV is a little scary for me.

the exit would be at the back of the hub where the motor is located. since its not a long shaft motor, the rotor is right on top of the motor. so the air is rammed right into and over the motor.
