Can I swing a GWS 9x5DD(9050) on a 3cell with this motor and a 12amp esc, on a 32" leadfeather yak?
I currently am using a 3cell 460mah, this motor, and a 8x4DD Gws prop, good for speed and power, but I accidently tryed a 9x5DD prop on the 3cell, and like the way it felt, way better at lower speeds, as it feels like it throws way more airflow over the surfaces than the 8x4DD. I am just worried about it being to much for the motor or esc. And I definately dont want to go back to 2cell, way to gutless compared to the 3cell set up!
A 9 by 5 on 3S will cook motor on your Yak 32.On 2S it'll be fine and it will fly it with plenty of power,but the Yak 32 likes the 8 by 4.3 better on 2S.
If you go to rcgroups the most used prop on Yak 32" 3D foamies is the GWS 8 by 4.3RD prop.
For indoors most use 2S 25C 460's,outdoors 3S 25C 460's to get through 15mph winds.
Turnigy nanotechs will have a much higher C rate,plus they are lighter.Great Li-Po's
I have built a few of the lead feather yak's and I agree with your view on going one prop size larger than the 8x4. I have built 2 for guys at our club using the cheap hextronix 24 gram brushless out runner - think its 1300KV with a 9x4.7 slow flyer prop. Try the hextronix motor its great. I use 500mA 3s zippy compacts 35c and a HK 10A ESC - lots and lots of thrust.
how com this motor wont run smootly when mounted with a "SF E-Prop 7x5 "? just sputters or wont spin completely. however when i mounted a "TGS Sport 5x5E Precision propeller" it seems to be working fine, motor and propeller spins and responds to controls smoothly. what could be the problem? motor defect? or mechanical compatibility issues?
What ESC you have and which battery? Try with 2S first. Also try to change medium or high timing for this engine. Also check that your battery is in good shape, fully charged and your esc counts number of cells corretly. I have same motor and it works great with 8x4.3 prop. Your 7x5 should be ok too.
actually blueocean2 the motor started respondingg smoothly with a 7x5 prop when i tested it again after posting my question. to give more detail of my set-up im using a "Rhino 610mAh 3S 11.1v 20C Lipoly Pack", ive read on the manual that the esc was suppose to "BIP" the number of times of the number of cell installed, my pack is 3S but the esc gives 4 beeps every time i connect it to the esc and turn on the TX. How do you change timing? my ESC is a "H-KING 10A Fixed Wing Brushless Speed Controler" Ive consulted the manual but havent got the hang of its witten intructions yet, i'm asian* maybe i dont undestand english very well. :-)
Another thing to check when the motor doesn't spin but seems to quickly oscillate back and forth spasmodically in just a few degrees of rotation is the motor to ESC connections, With only 2 out of 3 wires connected that is the behavior I have seen. It is also a reason it repairs it self when swapping around the hardware and another reason to triple check the solder joints and such so it doesn't occur mid flight.
jus got this item from the post office, It just dawned on me that this motor has 3 black wires with no color indicators whatsoever, so how am I supposed to know what are the negative and the positive wires? and what is the third wire for? were can i find a basic wiring diagram for this motor? I use to be into tamiya 1/10 RC cars so my basic knowledge about RC motors are on two wires, so I only just realised that a 3 wire motor is like an alien technology for me ... hope somebody can explain and give pointers on using this type of motor. how will i basically connect this to an esc and battery?
i need help on electrics,i am needing a motor for just a little foam wing.probally weighs a pound if that .the guy said to get a blue wonder 1500 and 10 a esc,would the turnigy 2730 1500kv be the same? would you recomend a 12a esc? what size battery would be good?
Yes that motor would be the same. 10 amp SS esc works good. But you could use the 12 amp if you like.
I run these motors on 1300mAh with an 8x4 HD prop
I have used 2100mAh but it will make the plane heavy. And I have used as small as 500mAh on a 3D plane with about 6 min run time.
Yes. It does the same or more work than a speed 400. But at a lower rpm and bigger prop. Aprox 7/5. So it works well with a 550gram plane using a 3s lipo. I use this motor for park jet F117 and my 24" saucers. Enjoy.
Hmm, what plane and weight? This will cruise: KD A22-10S Brushless Outrunner Motor sold here. Or: GH2212-06 V2 Brushless Outrunner Motor by Grayson Hobby. Wicked with a 6X4 prop. & 3s. (Flew this motor today on my wing.) Just depends on type of plane and weight consideration.
GWS.Grand Wing Design brand,props are more,thinner,flexible and light so they draw less amps. APC is another brand,close to #1 and is not available here,but at Tower Hobbies and are 3-4 times as costly. They are much stiffer and stronger making your motor pull more amps and over-heating motor.
roberted5 i wanted to know that whether can i use a 8*3.8 SF prop on this motor.my complete setup is 33inch 3d indoor flyer and GWS DD7*3.5 prop im using a 3s 450mah battery.7*3.5 is giving very less power and wanted to convert from 7*3.5 to 8*3.8SF should i use a 2s 450mah or 3s 450mah.please help me with this.Thank you
I also waited because it is an engine that is worth is very economical and strong my models is approximately 450g and I use this motor with a Turnigy esc of the 20th and a 3s 1300mAh battery, a battery life of 15 minutes flight
what size plane is it on and what type of flying are you doing? it sounds like you are using too much battery, weight wise, I fly mine on a 6 oz foamie and use a 500 MAH 3s Turnigy battery, my flight times are 6-8 mins. I don't think thrust is your problem, weight seems to be a larger issue
Muy buenos resultados, lo mejor de este motor es que funciona con cualquier helice que tengas teniendo en cuenta el rendimiento porsupuesto.Yo lo uso en un modelo de 160g con un ESC de 8 a 10amp y baterias de 7,4 360/500/800mah, es un motor muy eficiente y economico con una pequña bateria se puede volar casi 10 minutos.
This motor is commonly known as the "Red Wonder". It used to be blue. The 2730 1500KV is by far the most versatile motor for scratch-built foamies. The motor, paired with a Hobbyking SS Series 8-10A ESC, and a GWS 8x4 SF prop will be the perfect setup for your F22. I have this on my Dekan (rcgroups) F22 and it's sweet. Good luck.
I like the Turnigy 12amp Plush E 2Amp/BEC and it's plenty for a 8 by 4 DD prop on a 3S. A Turnigy 10amp 2amp BEC will work and I am using one on a 3S Li-Po and 8 by 4 DD right now,but the 12amp Plush E has a much more solid throttle response.
A 7x3.5 prop is generally a speed prop. It would not help. We also use a 8x4.3 prop but use throttle management as it will easily pull more than the recommended 8a max. The 7x6 sf also pulls around 12a. Try the 2730-1300 and a 9050 I think you will like it better and your battery will last longer too!!
I use a GWS 8 by 4DD with my 3D EPP foamie but the 8 by 4.3 is more popular.I use the nano-tech 3S 460's and get 7 minutes of outdoor 3D flying. My 32 weighs right at 7.5oz AUW.I use a Turnigy 12 amp Plush E ESC. I have unlimited vertical and can hover at 5/8 throttle.
I'm using the 8 by 4DD and nano-tech 3S 460's in the Leadfeather 32" planes and get 6 minutes of strong 3D outdoor flight.The company below is selling very nicely cut kits for 30.00 each and takes care of his customers. ****fancyfoam**** sells most of Leadfeather's designs now.
You don't have to limit the battery capacity for the motor. The weight of the battery is related to the wing loading of the plane. You can use 1000mAh or more as long as the wing loading allows the plane to fly as you want. The motor, prop, voltage combination is going to develop a specific amount of thrust. This needs to be adequate for the type of flying you want to do. A glider typically needs to be able too climb to altitude a few times and enough power to fly the glider back to the ground. You should limit the battery capacity to what you need for a flight. If 600mAh will do the job, it is a waste to carry more.
The allen screws in front of motor can come lose and your magnets to pull away from stator. If you can pull on the prop the outside of motor exposes stator,That'll make niose at full throttle,your prop is pulling the outside of your motor away from the magnetic field,plus your bearing are getting a load from behind on them. It can be fixed,I nosed in a few motors and that will cause the same problem.
What timing Should it be set at on a 2cell? Mines on 'High', it was flying awesome, but Im now experiencing loss of power, and its nowhere near as powerfull as when I first started using it(2weeks ago)
I recently bought this motor and hooked it up with the turnigy 9g ESC for the first time today.
The mechanic of this motor seems to be very tight, its pretty hard to move it by hand (when off and disconnected). When turning up the trottle it seems the ESC is not able to run the motor at low rpms, the first 20% of trottle only lead to the motor stuttering.
Is this behavior (that it is so thight) usual or should I be worried? The only comparison I have is a FC 28-05. That motor moves much more freely when turned by hand.
I as others are having the same shutter startup problem with is motor running many different esc's. Seems like the magnets are over kill and cause the motor not able to start easily. They changed from a year ago. It's a shame.
It's called cogging,all brushless motors cog,but having 16 magnets in a NSNS.. configuration,cause it to cog more. The older verion didn't have 16 magnets,but this motor is more powerful. I run my motors w/o prop 2-3 times for 3-4 minutes.It does help bearing throw out grease and loosen up motor.Then I prop it.
*waleed - this is an 8A motor max. Use any ESC you like that is 10A or more.
22 thumbs up!
Get this motor today. Looked very pretty. The full weight with propsaver and connectors is 31 gramm. Connectors diameter are 2mm.
Unfortunately, TURNIGY_BR_Series.zip archive doesn't include datasheet for this motor. So I made a few tests myself: Speed controller: TURNIGY Plush 12amp Battery: Rhino 1550mA 2S GWS 8õ4 / 7.5A / 330 gramm / 7800 RPM GWS 7x3.5 / 4.5A / 190 gramm / 9600 RPM Battery: Rhino 1250mA 3S GWS 8õ4 / 12A / 600 gramm / 10500 RPM GWS 7x3.5 / 7.5A / 450 gramm / 13500 RPM
Will use it with small 3S and 7x3.5 prop.

7 thumbs up!
Laminations are 0.2mm as advertised. Stator is slightly thicker than the old Blue Wonders but redesign of other components means no gain in weight. Efficiency has significantly increased due to these changes anywhere from 2pcnt to 5pcnt depending on the luck of the draw. Highly recommended as an improvement.
Going to use this one on a MS composit Swift flying wing. With a 8*4 GWS prop I could have about 600 grams thrust at 12A and with 7*3.5GWS about 410 gram thrust with 7A(read other revieuws for more info)
