Hi, i've tested a mini Quadrocopter with the 2g. hextronik brushless. It still works, but if you want to fly with a Camera, you should use a 3x2 prop.
I would build a hexacopter or octocopter with these motors, because you need some more power to get a nice flight, for loops and rools.
With 4 motors, my quadrocopter weights only 37gr. including everything and it wasn't so agil like a bigger one. I've used a 1mm carbon fibre frame and an KK board.
thank you for the help!ive also got one for you on a diff model if u have a good idea.im building a guillows piper cub 95.rubber band model.20 inch wing span.what would you guess a good esc and BL motor combo would be?im thinking 2s 10amp ESC but i know nothing about BL plane motors
Hi - just make a vertical hole - 5mm in the place the motors should be. Make a shortpiece of shrinktube over the end of your Motors ( where the cables came out), glue the shrinktube in the hole - so the motors can be detachable.
But better you use the AP02 more expensive, better to install and much more power.
You would NOT need a 2S bat,7.4v is to much for this motor.Your flight time will be determined by battery mAh capacity.More mAh's longer flights but more weight and that added weight affects flight time.Two motors will mean twice the draw on the battery so you'll have to decide what works best for you.
Bought 4 of these but they were all very unbalanced and the bell is even wobbly by some 0.3 mm so i had planned to balance them since they are pretty much unusable as they are now since im going to use them on a quad.
The bell isnt attached with a c-clip or so as far as i can see like bigger ones are but i cant take of the bell. Anyone know how to get the bell of from the stator?
Just to pull didnt do anything and im ofcourse afraid to break anything if doing wrong and i dont want to pull the bell of the axle either.
If you pull out the cables through that hole, you can see the stopper inside of the tube. The bell comes off if you just pull a bit - i did it accidentally before.. I guess with the right tools you can reattach the stopper - very fine ones. Or just leave it off, the pull of the rotor is not strong enough to pull the bell.
Man, you made me curious myself, so i took apart my newly built micro-plane and checked it out. It's a brassen-looking, conical ring on the axle.
You can re-attach it with the right tools for sure! i don#t know if you have to since i couldn't fell much of a difference. But i can't guaranty there won't be an increase of wobbliness on the .1mm scale.
I suggest, since the motors are useless to you in their current state anyway, to pull off one bell and look for yourself. Hope that helps. Good luck! i'd aprreciate your credit..
The motor is wobbely and pretty much useless in this state to the quad im going to use it for. But since they are now out of stock and i have a feeling that any other are the same i had planned to balance the bell but then i need to take it off, but now i will try this for sure, thanks a lot!
No,.. it is only 36gr thrust..i will recommend A05 PRODUCT ID: A05-2900 it have at least up to 46gr thrust ,and you can go up to 2S with no problem light set up A05 ,1S 240mah 6A ESC..heavy side set up A05 ,2S 180mah 7A 0r 8A ESC..hope it help
Where do you get prop savers for this thing? i am going to make a microcopter with these little motors but I will need to know how to keep the props on.. Not sure if I will build a quad or a tiny tricopter.. I think I tiny Tricopter with a micro servo would be fun.. going to use the kk board.. Not Hk so I could even make a hexcopter if the tricopter or quad doesnt have enough power.. Still I hsvre never seen a 1mm prop saver..
No prop savers available that I have seen. For a quad use the Air Hogs Aero Ace propellors (search eBay) ... they come as a CW and CCW pair that's perfect for a quad/hex. The hole needs drilling slightly to fit the shafts on these 2g motors.
I made my own bracket that just wraps around the shaft and screws onto the firewall. The motor is held together by magnets, so the pressure required to pull it out of a friction bracket is more than required to pull apart the motor.
It works perfect in the CB100. No problem at all,ordered 5 of the motors, because I regulary cracked the original Walkera tail motors (in my 4#3 and CB100). Did not destroy one of the Hextronix yet - seem to be much more durable than the original Walkera.
Do HK sell a prop that will push fit onto 1mm shaft for this motor? The specs just don't give enough info so it's really hard to find everything you need.
I'm trying to build a micro depron plane to 40g, this motor and the 3A 0.7g ESC (ProductID 9667) look ideal, but I need a prop that's going to give me enough thrust for some 3D action that will push fit on this motor without shoving bits of wood etc in the hole.
This is a good little motor but the shaft can easily bend, especially if you use a push fit as you suggest. A better way is to make a simple prop saver out of aluminium, brass, 1/32 ply or plastic glued with epoxy onto the base of the shaft. Hold the prop on with a lightweight rubber band (I use a ring cut from the finger of a rubber glove). You need to cut the motor shaft so that just a stub fit into the prop. See post 6 at: www.link
One of my friend already install this 2gram motor on his walkera cb100 tail and it work flawlessly, with one tip: it need to use shorter tail blade/propeller to work properly because the motor will work best on high rpm/kv.
So if first attempt your heli seem uncontrollable, try to cut both end of the prop/blade 1mm at one time until your heli "locked".
Does not metter, nothing will burn. You just connect and observe which way it rotates. If you need to change the way it rotates, just flip any two of the wires (not three, only two). By the way, if you do that without prop, never do it with full throttle as motor speeds up to much, it can burn up, or bearings will go.
That's going to be hard...
Well you need a brushless ESC and a servo tester.
Then you need something that makes a 3.0V-4.2V power source. then you connect everything... :-)
The other way is to make a small circuit, but i have no idea how to do that :-)

I got two today! I was very surplised to see their size, very small!! I measured their main dimension as follows Weight:2.02g & 2.06g Roter Diameter & Height:10mm, 4.9mm Shaft Diameter & Length: 1.0mm, 7.5mm (plusShaft boss hight is 2.5mm) Bearing tube length:8.1mm 12magnets rotor & 9teeth stator I really want to see how they can be assembled!

Received this VERY tiny outrunner today. I can really recommend getting it out over a white blanket so You dont loose it. I measured the amp to 1.7A with the suggested GWS3020(balanced) and a newly charged 130mAh FR-Cell. Running it while holding it with my fingers it felt pretty strong (torque).
As propatapter i can suggest a bit of shrinktubing (2mm?) on the axle and reaming the prop a bit for a tight fit because the prophole is too large. Cheap and easy) /Methuso

I tested these motors with a Turnigy 6Amp ESC, modified for 1S operation. Optimal settings for this Motor-ESC-combo are: - Cut Off Voltage: Low - Start mode: Normal - Timing mode: Low (or Middle)
I want to use this outrunner as a tailmotor for the DF4#3 micro heli, so I did some thrust measurements with the DF4#3 stock tail prop.
Full throttle speed: 20310 RPM Full throttle thrust: 16 gram.
I made the prop a bit larger with some tape (6mm on each side) Full throttle speed: 15700 RPM Full throttle thrust: 20 gram.
The standard DF4#3 brushed tailmotor (on full throttle plus full right rudder) runs at 17640 RPM.
The above RPM numbers seem to indicate, that these small outrunners could indeed be used as a DF4#3 tailmotor.

My tigermoth WS 35 cm, AUW 25 grams, flies very well with this motor!

I tried this amazing tiny motor with TGY DP 3A 1S 1g Brushless Speed Controller. Start up is smooth and spins very fast without any issue. I intend to use it in my 4#3b sub-micro heli tail, with its 1mm shaft, the stock rear rotor fits perfectly. It spins up the rotor to full throttle no problem at all..
