Just tested with a 10x4.7 SF prop (EPP1047)and 3s1p battery.
Max output
15.3 Amps:153 Watts:6800 RPM:832g Thrust
Other points
3.9 Amps:44 Watts:4500 RPM:350g Thrust
11.1 Amps:113 Watts:6300 RPM:692g Thrust
Estimated Constants KV=1035:Io=0.75:Rm=0.232
This motor is approximatly 10% more efficiant than the Turnigy 2209 28 turn motor with both runing at 140 watts.
Performs great!

Two of these are powering my "Protech Voyager", a foam twin-motor plane which looks like a twin star, 140cm wingspan. Fully loaded the plane weights 1300 gram, the motors can let it climb in a 60% angle with 9x4.5 props. Flying 20 minutes on a 2100 3s lipo (2 motors!). Taking off from grass without landing gear.
3mm connectors, adapter and prop saver are included in the package.

I like this Outrunner!
I use it in my MiniMag plane from Multiplex with a 10x6 GWS HD prop.
Great performance, the plane goes
vertical with a 11.1V LiPo battery!
Good Quality for this price, the
flexible cables are a further
advantage! You can't go wrong with
this item! An the accessories:
Just great!
Advice: turn the shaft and mount the
motor outside the plane for better
cooling to increase performance!
Greetings from Germany!

| A very good motor,and excellent value for money.In my scratch built, 1 mtr span, 652 gram aerobatic model,Using an APC/E 9X6 inch prop,an 1800mah LOONG MAX li-poly and a 25amp esc, vertical manuovers are unlimited.After a ten minute work-out, the motor is merely warm.This is a motor I could recommend to anyone with confidence.

| By far my favorite purchase here. Quality of the motor is pretty good. It's no Hacker on close inspection, not even close, but in the air I like it even more than my Hacker A20-20L. My test bed is a Slow Stick with a 11x3.8 APC SF prop on 3S, no heat build up at all. Give it full throttle and it jumps into the air. Throttle back and enjoy the flying. Will pull vertical until a spec with a fresh battery. With the ESC brake function turned off, I can put the plane in a full dive and the wind milling prop will keep the Slow Stick at a safe speed. Great fun. Supplied assesories withi this motor are very nice, especially for the price. Even includes wire connectors, fire wall mount, prop adapters for either end, spare shaft and screws. I wish I had bought more, and am sure I will. Smoking good deal. I can see using this on 3D, park flyers, and even small e-conversions.

New tests using this set of instruments: http://www.unitedhobbies.com/community/forum_posts.asp?TID=86 have confirmed previous findings. Due to longer warmup period, internal resistance was found to be higher than before: 0.27 ohms.
Measured values:
9x5 APCglow @11.05V: 12.7A 8720rpm 60km/h +29C
9x4.7 APCslow @11.0V: 13.0A 8520rpm 60 km/h +31C
10x5 APCelectric @10.9V: 15.0A 7230rpm 53 km/h +40C overheating
Please reffer to post mentioned above for testing method and results explanation.

| This motor works in a MPX EasyGlider Electric Sailplane with a 9x5 Graupner CamFolding Prop and 3s 2200mAh Lipo Hextronic. The motor takes between 11 and 12,5 A. This is a realy perfekt setup for long flight time and a good price.

Very good motor. I mounted it on a depron extra 330 - 500g, 10x3.8. Vetical lift with half-throttle. It becomes a bit warm only after 3D flights.
Now I have 2 of these motor.

| I bought one of these for my Lazy Bee and man it is awsome, what a great little motor with tons of guts, will take my Lazy Bee straight up no problem on a APC 10 x 5 20 Amp Hacker ESC and a 2000 mah battery. 1/4 to 1/2 power and 20 mins of flying.

| Nice little motor for my 3dx. Could not get the mount to fit. gave up and reversed the shaft instead. Extra parts are very useful. Surprised that it came with extra C-clips a and gold plated connectors. Excellent for this price.

| This hacker clone is great buy, I install it in my multiplex EasyGlider with a 10x8" Aeronaut prop, WOT less than 16amp, run time on a 3s1P 1500Mah Hyperion lipo exceeded 45mins with plenty of gliding in between. I am buying more for my other gliders.

I used this little outrunner on my MPX MiniMag. I'm using 3s2000 mAh lipos. At the begging I used APC 8*4 and APC 8*6 performance was very goof it didn't give me the verticals. I changed with APC 9*6 and it very quick and very fast. I'm using it GWS 9*7 now and still have 25-30 min flights.
it is a very good motor for that low price.

I had no intention of trying this little outrunner, but it came instead of ordered KDA 22-20L (kudos to UH). Lab tests revealed following data: Kv=1142, Ri=0.23ohm, I=0.77A @12V
Few props were tried with excelent Hex 3s 2250 mAh LiPo battery. All props above 9" gave excessive themperatures (14+ amps). Despite usual praxis, I would NOT recommend using slowfly APC and GWS props with this combo as revs are in 9000 rpm range where their efficiency drop considerably (2s combo should work much better). Best results were obtained using ordinary 9x5 APC prop: 9300 rpm @ 13.8A and 11.2V. Static thrust was 680g with 20 m/s speed, but efficiency is not much over 70%. Finaly, motor was installed in Jamara Extra 300 (http://shop.jamara-produkte.de/product_info.php?cPath=68_72_81&products_id=728).
All up weight is 620g (using HiTec HS55 servos, Hextronik 30A ESC and 3s 2250 battery). Great acro performance with unlimited verticals and flight durations well over 15 minutes. Recommended, but I believe there are better UH offers in this range with similar price tag.

| Ordered mine and it took only 7 days to arrive to WV, USA. I've got it running a 10 X 4 prop with a 2200 MaH LIPO. Very powerful and runs slightly warm with 50% full throttle. Pulls a 21 Oz converted

| May not be as effecient as my Hacker, but I can't tell the difference in the air. Flys my Puddlemaster great. Blasts off the water in about 15'with APC style 9x6E prop.

| This motor came with lots of neat extras. It out pulls my e-flite 370. I have had good luck with a 10*3.8 SF prop (3 cell li-po) and a 11*4.7 SF prop (2 cell li-po). I had trouble reversing the shaft, it is way too tight. I used an arbor press and plenty of w-d 40 lubricant. However, even with the right tools it was dicy.
