hexTronik 2 gram Brushless Outrunner 7700kv

 hotsam 250 points

sure you can. it just has to be very light! better keep well under 30g..

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.

Nice work! What did you use as a receiver for that?

 Max 21 points

yes, 1.5 max amp so 2a esc will be perfect and remember to keep weight to an absolute minimum. :]

thankyou for your credit :)

 christopher 20 points

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

 Max 21 points

hi, i think a 2s 250mah lipo, a 6a esc, a c10 micro brushles outrunner 2100kv and a 5x3 or 6x3 prop. or alternatively you could use the parts from a umx beast if you have them spare.

 nemoskull 49 points

no. auw is 30 grams, this motor puts out 19 grams. will not fly, or will be a very slow glide.

 Max 21 points

it says 36g thrust...!?

 Lukasz 20 points

I've just tested this motor with SuperMicro 5ch brick w/built-in 3,5A ESC and fully charged 1S lipo. Using the recommended prop I managed to get only 22g of thrust.

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.

 allan1951 1 points

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.

 Max 21 points

2 motors = double amp draw = double battery mah but still same 1s battery voltage

 Veli-Pekka 6 points

Yes, it's good for a quadcopter. You can drill a hole on the farme and glue the motor in it.

I used a piece of 5mm carbon fiber rod filed out for a tight fit, and glued that to my quad frame

depends on the prop you have

18 - 21g with a 2510 proeller.

 Superelectric 261 points

sorry but yes. they have a stoper. inside the little aluminum tube.. so if you try to fix it you probably will ruin it.

 hotsam 250 points

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.

 Henry. 52 points

Hmm some possibillity then, what did the stopper look like?

 hotsam 250 points

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..

 hotsam 250 points

update: I just fixed it! Fortunately i have a brass tube with 1mm inner diameter - it was perfect to secure the stopper again, lower diameter up!

 Henry. 52 points

Thanks for the checkup on this, very appreciated!

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!

 nemoskull 49 points

if you pull off the bell you will lose a gram of thrust on a gws 25XX. i did.

 Henry. 52 points

Havent done it yet but that sound strange, guess that the bearing have been damaged in your case.

 Superelectric 261 points

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

 Polycapman 56 points

Now thats super detailed help. Thanx superelectric

 GoldTiger 1 points

I think no, coz they have only /-36g thrust. Try somethink a litle bit more powerful. Like hexatronic 5g version.

 mig.21 100 points

This motor is aimed to use 1S 1 cell batery.

 ThatGuy 9 points

Thanks man!

 munsaf 291 points

Just take a piece of CFK-tube with the proper inner diameter that fits the motor. Now you can securely mount this tube in your plane and then put in the motor.

 adammooren 616 points

I wrapped mine in paper on the end then masking tape then finally cinched on by electrical tape and fitted into a hole in my plane

 TechnoFinder 126 points

i have the same issue in finding such. but will use some epoxy glue to hold it tightly

 Adit Diar 60 points

this motor is only fitted this prop: www.link

 B3n123 5 points

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.

 TechnoFinder 126 points

ADIT i too hate when links does not work.

stewart479 did you get your answer??

 stewart479 13 points

Yes I did, Thanks

 Nikers 192 points

If diameter C is 10mm i suppose the bearing tube is about the 1 third of it which is about 3-3.5mm

 Roy_T 134 points

The bearing tube's external diameter is 3.5mm

 nemoskull 49 points

people have used 3mm O.D. bearings to replace the bushings, so i guess its pretty close to 3mm I.D. (the tube)

 SumthinsFishy 72 points

There are 3 wires, and they are brushless.

 Daniel 8 points

Yes, this motor is brushless. I have a few and all be brushless :-)

 Glen 8 points

How long are the wires and do they come bare? Thanks.

 SumthinsFishy 72 points

Finally in stock now! I've been anxiously waiting too.

 TechnoFinder 126 points

yeah stock is there

 Shane 6 points

Greetings! The motor doesn't come with a bracket, but you can mount it by the back. I use mine as a replacement for the tail motor on my Walkera CB100 - works great, costs less.

 Headspin 14 points

Thanks for the reply.. Sadly the motor was faulty and went ***F.. the wires seperated at the windings.. Pretty dissapointed to be honest. Of course.. pointless sending anything back. Cheers.

 zxyanime 8 points

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.

 Guy 6 points

Yes that is what I did and it worked well.

 travatan 17 points

Walkera CB100 ile 100 uyumludur. sadece kablolarini lehimleyip hiç bir ayar yapmadan kullandim. Tamamen ayni motordur.

 donaldsnephew 152 points

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.

 Sudiptolal 6 points

You can mount it by gluing the back tube. But remember to leave a sufficient gap between the mount and the main drum so that it can spin freely without rubbing against the mount.

 Michel 1 points

Works great in the cb100, there is a mounting screw in the tail motor holder. Probably can use a small drop of ca to hold.

 robbie d 11 points

Unless you are running a gearbox, tests on other sites have shown that this motor will not reach more than around 20-25g of thrust. I think you would be looking closer to a 1:1 ratio for 3D.

 mrbob011 20 points

yes. look under the hardware/acc. section and the props are in with the spinners. they are 3x2 if i remember correctly and its like 1.99 for 5pc.

 Peter Mack 6 points

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

this motor is very weak. my 35g plane wont fly. i recommend u this motor for 3d>> www.link

 ishady 340 points

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". Thanks. -ishady-

 donaldsnephew 152 points

Use it in the CB100 tail and in the 4#3B tail - works perfect. No modification needed. Much more durable than original Walkera tail motors.

 ankurkaul17 111 points

No..just hot glue them ?

 Samuel 18 points

No, these props fit perfectly: www.link if you mean mounting the motor to the plane: just drill a hole and stick the motor in (Before soldering it to the ESC *-))

 Samuel 18 points

Just take a piece of CFK-tube with the proper inner diameter that fits the motor. Now you can securely mount this tube in your plane and then put in the motor.

 supermotostar 29 points

On the ESC you should have 3 connectors. I usually mark the cables and try connecting the cables differently until motor runs right and ESC doesn't give error beeps.

 Samuel 18 points

Just connect all 3 wires to the brushless ESC. If the motor turns the wrong way, switch any 2 of the 3 wires.

 Jaroslav 1 points

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.

 mikewoodez 1 points

Doesnt matter, just connect all three, and if your motor is spinning backwards from what you would like, just switch any two. Its that easy.

 BradleyK 69 points

it would not be easy, you need a brushed for this to work

 Samuel 18 points

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 :-)
