If youre serious about your quad-copters performance, then look no further than the AX-4005. Built with high-end 45SH magnets, a high pole count and custom motor mount, this quad-motor is designed purely for multi-rotor applications.
The AX-4005 includes a built in prop saver for GWS style props and a built in aluminum mount for quick and easy installation on your quadcopter frame.
This is not a modfied aeroplane outrunner. It was designed from the ground up for quad copters.
Specs Kv: 650rpm/v Turns: 24T Resistance: 0.147Rm Idle Current: 0.6A Can size: 45mm Can Length: 10mm Shaft: 3mm (Includes Prop saver mount for GWS style props) Suggested ESC Amps: 20A Rated Watts: 130W Weight: 59g Cell count: 3~4S Lipoly
the bearings on these motors are poor
i have a set of these on a monocoque carbon frame , one piece frame and super stiff .... the bearings cause a audible vibration
i would look to buy a motor with a thicker shaft so that bigger bearings are used ..
Before you purchase anything for your quadcopter, ask yourself first, what do you plan to do with your quad? Is it for FPV flying only? Do you plan to put a camera? What size of camera? And, how much are you willing to spend on your quad?
Basically for a quadcopter you need an FC (flight controller), a frame, 4 motors with 4 esc, a lot of lipo batteries and this excludes the tx/rx unit which I'm hoping you already have.
goodevening everyone and i am sorry for my englich....
i want to make a quadcopter and i need your help for the electronic parts and for the motor ..if anyone can help me send me some detals.....thjank you about help...
Basically you'll need:
1)a quadcopter frame (to mount everything on)
2)a multi-rotor control board (the brain of the quad)
3)4 speed controllers(they control the motors)
4)4 motors
5)4 propellers
6)a battery
7)a transmitter/receiver system
You should first visit some websites on making a quadcopter(google it) to get an idea of the whole process of building the quad and then buy the components.
Building a quad from scratch requires some skills and a lot of patience, so if you lack any of these traits ,try a ready made kit ( plug n fly), a small one would be better, so as to master your flying skills.
It is a 130 watt motor so with a 3cell lipoly you will need around a 15amp speed controller,this is assuming a single motor,in a Quad then a 60amp wouild be best.Battery wise for a single motor then something like a 2500mah would be good.
Actually...
In a quad, you'll need 4 speed controllers, each at a 20A rating. Typically, you can't run 4 independent motors from a single speed controller.
It's one thing to give out info to help someone, but to say such idiot answers is just digging for points. Hope it doesn't cause a crash to the operator or an innocent bystander.
i just at the spec and the dt750 is more efficient and cost 1/3 the price so even if the bearing are not the best one on the dt750 you have 3 motor for the same price of this one
These motors are far more efficient that the dt750's in real world circumstances. I saw a guy on youtube fly his tri with these motors for 25 minutes. I get 12 minute flights with the dt750's on my tri... If this helped and is the best answer, please credit me.
Hi can someone help me please?
Im making a tricopter and Im not that graet with electronics, will this motor will I achieve greater autonomy flight will it be WITH THIS 620kv OR WITH A 850kv?
Regards
I'm not the best with this either, but I would say 620kv since it it spinning a larger prop and it doesn't have to wind up as much as the 850kv to get more lift. I wouldn't go for this motor if this is your first quad. You should be able to get all three motors for around $40... Make sure the thrust is the some on both motors and consider that in your decision.
You're very welcome. What did you decide to go with. I know as of yesterday the dt750 were instock. Those are very popular and a great value. You can get a buddy code and get a great deal!
I built one about 6 months ago. I crashed though, and bent the bell on a motor and ruined my kk board. My kk2 should be in any day now and I'll have mine back up in the air! Happy flying.
Watch davids episode about the tricopter on flitetest on youtube. He talks about rates and expos. Acro mode works just fine if you don't care to have a throttle curve.
Pauloh.. Low KV motor will be more efficient. But if too low, it need more torque and will be too wobbling on wind condition. I propose you to get high efficient motor directly rather then normal motor. Later on you need to upgrade the motor for long flying time.
No question just one comment. This motor has a 3mm shaft. I try to stay away from motors on quads with 3mm shaft. Just ***p a blade and you have a bent shaft. If these were 4mm or even 5mm they would rock.
I am planning to use these motors on the Turnigy Talon V2 carbon fibre frame. Have any of you mounted them on this frame or have any similar experience? Holes sizes and spacings do not match up.
Hey guys, I am using this motor along with GWS HD8040 3 Blade Prop Counter Rotate (2pc) , as a testing propeller, I connected my (cheapo) multimeter, and I am measuring current draw as 2.6A at maximum speed, is that possible?! doesn't it have a 15A current draw or something?
Use low pith small propellers like 1047 or 9047. It will help to maintain smooth flights. My recommendation is 1047. Im using these in my tricopter since 4months. 9047 also good but the problem is my tricopter weight is 1.1Kg so its bit hard to elevate with 9047.
Could you please tell me how can I remove the additional prop adapter?! I need to install a 1147 GWS prop and I can't figure a way to remove the installed adapter
Thanks HaKK ** where did you buy your 2.5M screws? I can't find them anywhere, and Hobby King support won't help. I spent over $120 (US Dollars) on these motors, and I can't mount them! Please help!
Yeah ** I visited the local hardware store that specializes in nuts and bolts ** the smallest they had was 3M. I live in the USA, where metric is considered "wrong" ** so anything metric is really hard to find here. I really wish the USA would finally convert to metric ** sigh...
Yeah, I spent 4 years there saluting the flag on daily basis and at least all US military maps are in metric, so there is a start in an area where you really can't f... up your conversions :) This just gave me an idea though. I checked in Wiki that Canadians are way ahead of you in metrification (metric is French led to start with :) Try canadian on-line shops "metric bolt canada" gave me lots of good answers. And S&H from Canada should be as good as within continental US.
What is the recommended prop for this motor? can i have the link pls for counter and non counter props? what do i need to mount motor on HobbyKing Quadcopter Frame V1? I will give credit
Thanks GH-1234, so ESCs works like DC-AC converter? I search and learn their theories, but i dont think it works like you said.
I think something else is going on ..
Hey everybody, as GWS style props adapter is included which propellers can I use for my quadcopter? Everybody recommends APC propellers for quadcopters but can APC propellers fit on this adapter?
Hi, you can unscrew the 2 hex screws that hold the additional aluminum prop adapter (with a rather thick shaft). This will leave you with a motor shaft sticking out and the 2 longer set screws that are meant for rubber ring mounting of props. Now you can use GWS style props on your quad :) I am building a guad with NX-4006 motors at the moment, because the lighter NX-4005 motors were out of stock for a while.
Bevore 1 hour I got email that this article is on stock now. But is'nt. Furthermore I can't backorder http://www.hobbyking.com/hobbyking/store/images/em_c ry.gif
Nice wide can motor for quadrucopters. The additional prop adapter is handy for sturdier props, but if you want to go with GWS style or other thin shaft props then you can simply remove the aluminum prop adapter and use the rubber ring to mount directly on the shaft and making use of the 2 very long set screws the motor comes with.

I got mine for use on a Quad Copter. I havent tested it yet, it looks great, and I think it will be very powerful. The finish is great and the mounting holes are a good way to mount them!
This motor does not fit on HpbbyKing quadcopter frame V1!
Be carefull. I don't understand why HK does not advise for this.
I will adapt a frame dedicated, but really I am not happy for this.

Really smooth running and well made motor.Keyed magnets,silicone wires,grooves in shaft for the grub screws to lock into.
The shaft is held with two grub screws and the supplied prop adaptor has two grub screws too.It is a snug and secure fit.
On my 1kg quad i am using 10 by 3.8 apc slowfly props.This fits the adapter with their supplied 5mm ring.Getting 12 mins on a 2200 3 cell.On an 1800 4 cell the quad is really powerful and will easily lift another 400 grams but the motors are still barely warm.
Note-The outside three holes are for mounting, and require M2.5 bolts.
On a shallow note,i really like the look of these low profile motors..
