I have lose 2 nuts that conect motor for the motor mount.My all there motor have lose them.Any suggestion for that?Anyone know the name for those little nuts?Where can I buy sapre ones?
I threw all the information in a calculator that I use (just google rc thrust calculator if you want to try it. Its the first one on the list) and at 68 degrees Fahrenheit, I got 340 grams of thrust with a 2 bladed prop and 480 grams of thrust with a 3 bladed prop. Not sure about amp draw but that's what I got. Hope I helped.
I do too. ,although I only run a 350mah 3s. On sure that with a 2200 mah 3s, you get crazy long run times. Anyway, I also forgot to mention that two bladed props are more efficient than three bladed ones. This is due to when the prop spins and it has 3 blades, the blades are so close that they hit the BC ackwashed air from the last blade. Two bladed props get clean air all the time. In conclusion, more efficiency= more flight time but a little less thrust.
Have one of these on my f22. I was at the field when the wire broke. Nice motor with two issues. 1. The wire and 2. Is that to get the set screws to stay, you have to crank them down so hard that they strip. But hey the price is right.
Hi! I'm thinking of putting this motor on a RcPowers Extra 300 profile depron plane. AUW is about 250 grams (almost 9 oz) including a 1000 mAh 3S battery (about 95 grams, 3.5 oz). I would like to use a 8x3.8 slowfly prop. Would you say this is a reasonable setup for acrobatics / beginner 3D? A 10A ESC should be enough, right?
I am testing mine with a GWS HD8060. The thrust is incredible for this small motor. At WOT on a fully charged 3S it exceeds the "Max Load" current identified in the specifications, so I don't run it at WOT until after the voltage starts to drop. It has also survived numerous crashes. Overall, I am very impressed.
No, it's too heavy - the weight of a propeller would be close to the weight of motor - it's just not a good choice.
I suggest the GWS style or Tower pro SF propellers, 8x4 is a good size. They have a larger surface to help in giving more thrust at a slow flying (JXF is designed for fast flying like when you use 1800kv more powerful motor).
Thank you RCFG! I want to restrict my battery to 3S only - is 6x3.5 the smallest prop I can use with this motor? If so, how much thrust will this combo give? It'd help in designing the plane. Thanks again.
I used all the way to 9x4,7 SF prop and got 350grams plane going strong.
On the flip hand i got allt he way to 6x3 and it doesnt have as much power at all.
I THINK that 6 is smallest prop you can put and not have total loss in power.
If you wont smaller prop use some of the smaller props of hextronix i use them all, 17grams, 10grams even 5 grams for smaller purpose.

Help please?! I am using this motor with a 3S-15C 1000mah li-po and have a 8x4.3 GWS prop attached with the stock prop saver. Problem is, at full throttle the prop keeps pulling itself forward and off of the prop saver. Do I just need to put on more rubber bands or what?
I had issues with the included prop saver as well, particularly the rubber band it came with, way to loose. I have since moved on to using colet styled prop adapters. O-rings, found at a local hardware store work great as prop savers.
Nothing worse than punching the throttle and having the prop fly off and flop all around. I have used the lightest zip ties I can find with good results. Far cheaper than o-rings and the zip ties will break most of the time before bending or breaking shafts.
Harbor Freight has O ring assortments for $6 that are great to use for this stuff. The problem is that if yu use a HyperDrive prop the hub is much bigger and will need the supplied O-ring. I regularly use two rings to hold it firmer
If the prop saver slide off, then you have to look scarf (flat surface) on the shaft, as
* not be left without a scarf on it, if that's the problem, you need to produce.
Best thing to use for bands is Large bore Silicon Tubing as sold for exhaust extensions etc.
Use a razor blade etc to cut thin sections off the end.
Ready made bands that do not perish like O rings and depending on thickness you cut you can adjust strength.
Absolutely love these motors, been flying them in my quad for about 6 months now. The bearings are starting to go out in two of them though. I'd like to breath new life into these motors by replacing the bad bearings. Does anyone know what size bearings I would need to get?
Hi, ive got a 2s battery, 430mah 20c and have some 9x4.7 props laying around and some 8x3.8 props. Which would be better on the motor running like this?
I would use a 9x4.7 prop. I use an 8x3.8 prop and a 1000 mAh 2s, but its a little bit underpowered. My planes has a 20" wingspan and it only weighs about a quarter of a pound.
With 8x4.3 works well at high speed in light aircraft, to fly with 8x3.8 slower. Make sure that the motor is cooled well, and not forced, because www.link
What is the diameter of the screw holes on this? I want to get some screws to mount it onto my plane but i dont know what size screws to get. (I'm also surprised these didnt come with the motor)
hey i have one of these and all i get out of it is beeps that's all it does i thought maybe the throttle was reversed but that's not it can anybody help on this? thanks!
Out of stock
I am trying to get a motor for the flite test nutball i am building they recommend that I use a
HEXTRONIK 24GRAM BRUSHLESS OUTRUNNER 1300KV
Red Brick 25A ESC
Turnigy 500mAh 2S 20C Lipo Pack
The Esc and Motor is out of stock
What else can i use ?
Well, if you look at the specs, this motor draws well under 10 amps, so if you are planing on using a prop that will keep its max draw at around 8amps, like the recommended 8x4 prop, you could even get a smaller and lighter ESC. I am using this motor with the Plush 12amp ESC and have not had any problems so far.
On the box, it says the model and the Kv. Sadly, unless you are a motor expert, I am not sure you would be able to tell them apart. You could write with a permanent marker somewhere on the motor what is its Kv rating, and keep track that way.
you are welcome. i believe that is a perfect match i would begin with a 3s set up for that if its less you can do that but well its not pretty if its not enough. happy flying.
where do i get this wire to redo the motor. i took the wire off after it was broken and see exactly how to do it now i want to try i think if you do the same amount of wirearound 12 or 13 times every other one untill it wired using three seperate wires and starting points. i hope lol does any one know if i can put on more to make it faster or stronger?
i think it depends on what you intend to fly it with. is that a 450mah2s or 450mah3s? if 2s yes if 3s go 15 to 18amp but even more important whats it going on? how heavy? i am imagining a foamy profile epp or biplane 30 inch wing span or less i hope? hope this helps you some. tommy
I use them on my flat foamie Yaks with the HK 8-10amp ESC and they are fine. The motor with a DD8040 prop on 3S only draws about 6amps. The red JST connectors on the batteries are only rated 6-7amps continuous or you melt them

These are great little motors for the price. I bought one and then got two more. I use them on home made foamie planes from 8 - 16 ounces. They will take most of my foamies unlimited verticle. I use 2 and 3 cell lipos from 350-1500 mah and props from 8x4 to 10x4.7 on them. Here is some data. UH BLUE Wonder 1300Kv Prop size= amps / thrust in ounces 2S 8040= 3.3 / 8.2 9050= 4.9 / 10.8 9047= 5.3 / 10.9 1047= 6.5 / 11.5 3s 7035= 4.2 / 9.5 8040= 5 / 13 7060= 6.3 / 11.3 9050= 6.6 / 14.6 9047= 7.6 / 15
I also got a 1500 kv one to try out.

Propeller data for 3 cell Lipo batteries: The GWS EP 9050 produces about 18 ounces of thrust at 9 amps with a pitch speed of 34 mph. This is my favorite prop on this motor. The APC 9x6E produces about 17 ounces of thrust at 10 amps with a pitch speed of 36 mph. The APC 9x3.8SF produces about 18 ounces of thrust at 9.5 amps with a pitch speed of 25 mph. The APC 8x3.8SF produces about 15 ounces of thrust at 8 amps with a pitch speed of 29 mph. The GWS EP 8040 produces about 15 ounces of thrust at 6 amps with a pitch speed of 34 mph. The GWS EP 8060 produces about 14 ounces of thrust at 8.5 amps with a pitch speed of 39 mph. The MA 7x4 3-blade produces about 10 ounces of thrust at 7.5 amps with a pitch speed of 36 mph.
Propeller data for 2 cell Lipo batteries: The GWS EP1060 produces about 12 ounces of thrust at 6.5 amps with a pitch speed of 28 mph. The APC 9x6E produces about 11 ounces of thrust at 6 amps with a pitch speed of 29 mph. The APC 10x3.8SF produces about 12 ounces of thrust at 6.5 amps with a pitch speed of 17 mph.

Great bargain, high efficiency, great for little foamies!
I measured resistance, no-load current and Kv to get data to plug into Motocalc.
Resistance, R = 0.319 ohms No-load Current, Io = 0.22 amps at 6 volts, 0.30A at 9V Motor Constant, Kv = 1079 rpm/volt
These data differ a bit from the 1300Kv and 0.5A listed in the ad, but this is what my motor measures, cold.
One excellent little motor, both in performance and build quality. As others have noted be careful about bending the wires where they exit the windings. Mine came as shown, without connectors or hardware.
