The AEO RC MM1914-1100 / ADH300L is a very nice small but powerful outrunner that is narrow enough to fit in small glider noses. It is excellent for electrifying most of the F3-RES models we sell. Suitable for electric models weighing up to about 650g.

It can be pushed to about 150W on 3S LiPo batteries or 100W in 2S LiPos.

Note the manufacturer label the motor AEO RC MM1914-1100 / ADH300L but we measured the Kv as 1280 RPM/V

Interesting RCGroups assesment.

Excellent motor

Very good value motor. Small but powerful. ESC needs to be set to correct timing.

Decent motor

Smooth motor, but wrong mounting holes completely for the res dart even though its recommended.

Not there yet!

I've tried two of these and cannot get them to run properly - one of them burnt out. Having tried to eliminate problems with other gear, ESC etc. I suspect that, as I tried to test them in a jig mounted in a cast iron vice, the vice has interfered with the magnets in the rotor. I won't do that again and I've tried to order another one but they're out of stock. Still hoping to get my Circle Dancer flying before winter!

Good motor, easy transaction

Very nice site, easy ordering process and fast delivery. And a good little motor too, excellent product.

Small problem

Had a problem with the motor I received, it would not turn. At closer examination I found there was glue between the windings and the bell. Once I got it apart and cleaned it was go to go.

Little gem

This is a powerful little motor. Ideal for F5RES gliders where space is tight.
It feels quite stiff to turn but goes well when powered up.

Good as gold, as per usual.

Quick delivery service.
The kit is well made and the plan is excellent.
The online instructions were a bit lacking in parts.
Would help if the parts were numbered.
The quality of the wood is excellent.

Brilliant service

I ordered an ADH300L motor on Friday afternoon at 16:23 it was despatched at 16:28 and I received it on Saturday morning before 10:00. Brilliant service again from Hyperflight and the Post Office. Many Thanks. Terry.

Very disappointed on a number of accounts.
1) No plan
2) Parts are not numbered.
3) English instructions revert back to German half way through.
A friend who bought the Peres has a much better kit which is also around 70 cheaper
Service from Hyperflight excellent as always.

Comment by:

Usual good service looks to be just the job to fit in the tight space in fuselage.

Great motor, fantastic service

Put one of these in my home built Allegro Lite (480g RTF). Great performance using a 9x5 GM prop. Was impressed enough to buy another one for the next eRes model I build.
..and as usual, the service from Niel's shop was perfect. 2 weeks from his farm to mine on the other side of the world.

 Review by:

I purchased this item to use in 2 metre competition gliders and they are perfect for this application. Although a cheap and cheerful motor they are as good if not better than motors costing three times as much. Particularly like their small diameter which fit perfectly in the narrow fuselage often used these days.

Tiny motor

This tiny brushless motor seems to be very solid. It can turn an 6x4" prop with some gusto.
Will say more once it is in a plane (PicaRES).

 Review by:

Good product

Needed a small brushless motor and read about your company. Ordered it and received a good product and an adequate delivery.

 Review by:

Excellent little motor which gives plenty of thrust on 2 cells mines in an O/ D lite weight 2 meter glider with a narrow front fuselage where your standard 28mm outrunner wouldn't have fitted.
I inadvertently ran it with 3 cells on a 10x6 and it still works !!

Impressed with this little motor

Bought this for an own design glider that used Hyperflight's Sapphire pod and boom.
It arrived in good time, and I was surprised how small and light it was. You never get a feel for these things even though the photos and specs give you the info!
Fitted without fuss and with the offset spinner and carbon 11 x 6 blades it really looked the part.
I had problems when using a Castle Creations ESC. It would not start consistently and would rattle / stop at anything above idle. This ESC did not offer any timing options, so I swapped for an EnErG and this sorted the problem. With the 11 x 6 it pulls around 95 - 100W on a 2S LiPo and pulls my little 1.5M span 440 gram glider up at around 70 degrees.
Only had three flights so far - hence only 4* at the moment - but so far very happy with performance and quality.

Failed after a few uses

I bought one of these to go in a Horesji Geronimo - turns out it was a bit underpowered with a 3S battery and a 9x6 prop but it worked OK. But after about 5 flights (maybe 10 minutes running time) it failed, with one lead now open circuit.

I reckon this is unrelated, but while inspecting the motor I also found that the spacing between rotor and stator varies from about 0.6 mm down to about 0.2 mm - a less serious version of David Still's fouling.

 Review by:

so far so good

I have not run them even less mounted them but they have strong magnets, much stronger than normally found in a motor of this size and they appear better made than some. We will see how they go when I have them in a plane.

RES Dart and this motor

Purchased an E RES Dart, and this motor. Looking forward to flying. The kit is very ingenious but the fun is translating the german building instructions as the english translation available is little better than Google Translate. Having said that, I have found Hyperflight service exceptional, speedy and friendly. Thankyou.

Second ones fine

I ordered one of these with a RES olution kit after installing it I couldn't get it to work it just jittered the odd time it did go it sounded very rough and on inspection the bell housing doesn't appear to be on straight, I emailed but heard nothing back so ordered a second witch runs fine with no issues so far.The first will be sent back for a refund.
