I use the D2830-11 1000kv outrunners with 10x4.7 SF props on a selfmade Tricopter. First I hat the FC-2822 (1200KV) installed but was not satisfied motor holders of the FC-2822. This motor comes with all accessories in the pictures. It performs much better than the FC-2822. The flying time with nano tech 2200mAh/3S LiPos is up to 13 minutes depending on the throttle you use and the motors keep cool.
Thanks again, EA - looks like your recommendation (D2836/8) is a better option. How does this compare to another popular motor, the DT750? Now that we're talking big props, shouldn't we consider this motor too?
Hi Randy, Thanks for the credit. The DT750 is a good motor. I've used it on planes and it will turn a 11-12 inch prop, but it weighs more and has about 10%-15% less power than the D2836/8. It's your call at this point, but my choice would be the than the D2836/8 over the DT750. Cheers, EA!
Hi Carlos, HK doesn't sell a replacement shaft specifically for this motor so you have to substitute a 3.17mm shaft from some other motor. The shaft you use must have the groove at the rear end of the shaft for the little circlip to lock into. A shaft that will work on this motor is PRODUCT ID: KDS-20-L ($2.15), but unfortunately they are out of stock and have been for several months. There's no other shaft that is as close a match. Cheers, EA!
Thanks EA. I tried checking this on eCalc, and according to the app I SHOULD be able to do 11 and 12 inch props (yes, on 3S). However, I was asking because I have not read of anyone trying it on any forum, hence my suspicion that it isn't right.
Any idea what kind of thrust I can get on 10x4.5 props/3S? Maybe I have to rethink this idea and go with a bigger motor?
Hi Randy, The e-Calc estimates are probably based on high-efficiency/low-drag electric props, but you would probably be using the wide-blade SF style props for a quad. These create more rotational drag so your limit as to max size is a bit lower. This motor on a 3S with a 10x4.5 prop would probably deliver 900g-1000g of thrust/lift. If you'll need more lift per motor than that you might want to look at the D2836/8 1100kV motor. It will swing a 11-inch prop on a 3S with no problem. You should see approx. 1200g-1300g of thrust. It's a very popular motor with the quad guys and the screw pattern (16mm x 19mm) will mount straight onto most quad frames. Cheers, EA!
Hi Randy, Most of the quad guys run this motor on a 3S with 10x4.5 props and report very good results. You could turn a 11 or 12 inch prop on a 2S, but on a 3S you would actually see less thrust and lots more heat than you would on a 10x4.5. Cheers, EA!
Hi Sean, You didn't mention how many cells you plan to run the motor on, so I'll cover all the bases. A 10x5 APC on a 2S .... no problem, you could even go with more pitch. A 10x5 APC on a 3S ... it will turn it, but you're right at the top of the prop range for a 3S so make sure the motor is well-ventilated or it will run very warm. You would be better off backing off the pitch to a 10x4 or the length to a 9x6. A 10x5 APC on a 4S ... no way, you'll fry the motor. Good luck! Cheers, EA!
Hi EA, I'm running two 2830's on 10x6 MA Style Electric Props on 3S(1600mAh20C) both run well within spec, no sign of heat at all, getting 18 to 19 minutes of mixed throttle flight time with a bit of full throttle acrobatics thrown in. On the bench at WOT I am seeing 12.47v battery sag to min 11.5v* output peaking at 16.64Amps (195watts) I'm tempted to prop up to 11x5~6 and see if I can get the other 10watts out of it :)
Hi Mick, The MA Style Electric Prop must be a much higher efficiency design than the SF style props I usually run for 3D flying. I run a 9x6SF on this motor with a 3S and it's pulling 19A at full throttle on the bench. However, SF props are designed to deliver lots of thrust at low throttle settings, but this results in inefficiencies at higher RPMs. The APC prop Sean wants to use would probably run similar to your results. Thanks for providing such good info! Cheers, EA!
There is one that is made for it, but it's not sold here. I have them and they are much better. The NTM ones may fit, need someone to try them. Use your G search engine to find this 2830 Prop Adaptor MA-02, click on the first link.
Hi Paul (and Senator), Sorry I think you are right the 2830 motor has 4 holes. It may fit the 2826 (3 hole). I have ordered a couple to try on some 2826's I have here but for sure it's not for the 2830 (4 hole).
This motor is excellent for any MR. They are efficient so you get good flight time and the bearings are quiet, smooth and last a long time.
I use them on all my MR's, be it tri, quad, hex or octo. I've tried many motors but these are my favorites, very reliable. Nothing in the $10 range will come close. Buy them.
Hi, Please suggest me connectors that i need to use to connect this motor to 30Amps ESC. Also if possible please suggest connectors that i need to use to connect 30Amps ESC and 3000mAh 3S Turnigy battery. Thanks! Krutarth
On this product( PRODUCT ID: AM1009x10)it says "Good for wire up to 10AWG thickness.". How would it matter if I use 18AWG wire since wire coming out from ESCs are 18AWG thick ?
Hi Krutarth, 10AWG = 2.59mm - they say that the connectors are good for wire up to 10AWG so you know what maximum thickness you can fit into it. Your ESC 18AWG will be 1.02mm so they will slide into the connector for soldering very easy :)
Hi, Could someone please suggest the remaining components that are required to build quadcopter from scratch.
Following are the components that i bought from hobbyking:
1. arduino mega 2560* 2. itg-3205 gyro* 3. bmp085 barometer* 4. hmc5883l compass* 5. neo-6m gps module* 7. 10x4.5 SF props* 8. d2830-11 1000kv brushless motor* 9. 18Amp turnigy ESC* 10. turnigy nano-tech 3000mAh 3S 25~50C Lipo* 11. sk450 glass fiber quadcopter frame*
Above are the components that i have with me right now. I am worried that i am forgetting few components like bullet connectors and stuff. Please suggest me what else am i left to buy?
Hi Krutarth, I'm not 100% with quadcopter but the 18A Turnigy ESC (Basic) does not have connectors on it, so you would need battery end (whatever you are using e.g. XT60) and the motor end would need 3.5mm bullets like the polymax PRODUCT ID: AM1001A. You will also have to look at the hub of your props as the collet on the D2830 is large around 6mm or 6.35mm from memory, not sure the SF have adaptors as they seem to have the hex nut shape on the back. The other stuff is unknown to me as I don't fly quads. How are you going to connect all your ESC power leads, you can do it by just soldering and heatshrink but there are also some neat power distribution options for quads that you may like to look at e.g. SKU: 9171000033
Hi guys, im new to building quads and for now im thinking of this configuration:
- Hobby King 2.4Ghz 6Ch Tx & Rx V2 (Mode 2)
- HobbyKing Multi-Rotor Control Board V2.1 (Atmega168PA)
- 4 D2830-11 1000kv Brushless Motor
- ZIPPY Flightmax 2200mAh 2S1P 40C
- 4 Turnigy Multistar 30 Amp Multi-rotor Brushless ESC 2-4S (OPTO)
- Im not sure about the prosp.
Is this a Good config?
Please let me know.
Hi Alex, Thanks for the credit. Regarding props, the way you phrased your question made it sound like you were setting up a plane. If you're setting up a quad you will be limited to props that can be bought in counter-rotating pairs. The 10x4.5 would fall in that category. I'm not a quad flyer, but a 3D plane flyer, so I don't want to be the final voice on this question. You should re-post your question on this board as a quad question and those guys will get you sorted out. Also, If you plan to run all 4 motors off of one 2200mah/2S LiPo you may come up short, as this motor draws over 15A fully-loaded. Very few 2200mah LiPos can deliver 60A (4x15A). Cheers, EA!
* ElectricAussie: Question, how did you determine thrust power of this motor? I ask because I would like to know what the thrust is of the NTM 2826 1000kv motors since I am putting 4 of them on my quad with a 3S battery, and was wondering what the total thrust would be for the four motors? Any help you can give is AWESOME, thanks!!!
Hi Brian, Sorry for the late response. I didn't realize you question was sitting here waiting. With planes, determining thrust is pretty easy. I use a small spring scale on the bench hooked to the tail of the plane an run the throttle to full. That gives a reasonable estimate. I then verify at the field using throttle position to hover the plane as a guide. If plane weighs 600g, scale showed 1000g on the bench, and plane hovers at 60% throttle I'm pretty confident of the 1000g number. It's not an exact method, which is why I usually give a range (100g?) to the low side when I answer questions on how much thrust someone can expect with a certain set-up. Cheers, EA!
Hi Alex, That prop is fine for this motor on a 2S and 2200mah will give you lots of flight time. However, you won't get the maximum thrust possible from this motor. A 10x7 would be better. A 10x4.5 would even work with this motor on a 3S, but it would be right at the top of the prop range for 3S. Cheers, EA!
Hi Adrian, A lot of quad flyers are saying "yes" (see other posts above and below) to the 10x4.5 prop on a 3S for quads. The 30A ESC is definitely a must for that set-up, as you'll be drawing over 20A at full throttle. Cheers, EA!
Hi, I can understand that I have been posting often past few days, but since I am building it for first time, I want to make sure that I create less number of mistakes.
Could somebody please let me know how do I determine speed of motor for it to be able to lift quad ? What I am thinking is I gradually increase speed of motor until motor lifts quad.. Am I correct?
Also can you let me know how do i give that speed through arduino mega board (I mean I know using PWM pins, but what values has to be transferred)?
Few specs that might be helpful:
Motor: d2830-11* prop: 10x4.5* battery: 3S 3000mAh* Max possible weight for my quad: 1.2 Kg
Good to ask questions Krutarth, if people have knowledge they can share with you. I don't have any quadcopter experience but there are is some good reference on the net. Try google "flight theory multi rotor getting started" www.link theory is pretty simple 4 motors, 4 props, 4 escs, controller board, receiver, add some power and throttle it into the sky. Your 4 D2830-11's with 10x4.5 on 3S will have enough thrust to lift your 1.2kg
I bought 18A ESC along with D2830-11 1000kv motor from hobbyking. Specifications mentioned in motor says it has to be 30A ESC. Would it create problem if I use 18A ESC with this motor? If so, is there any way that this problem can be solved ?
Hi Krutarth, This motor will draw approx. 20A with a full-load prop. Not only would your 18A ESC be operating at or above its max current, but it would likely fail if you ran it that way on a regular basis. The result could cause a crash, so you need to either get a bigger ESC or use a smaller prop. A 8x4 on a 3S LiPo would be a reasonable choice. Cheers, EA!
I'm with ElectricAussie on this topic. We can read lots of blogs where people are successfully flying 3S motors on 4S batteries, or drawing 35 amps on 30 amp rated ESC's etc. This can and is being done, but anytime we reach or exceed electric or electronic devices maximum for either voltage or current we are risking unnecessary overheating and stressing of those devices. They may keep working or they may fail (do you feel lucky). I just don't think it's worth 'risking' a model, or worse for the relatively low prices of ESC's and brush-less motors with suitable ratings for the job. 3S to 4S = voltage 33%. Would you run your new 240v flat screen TV on 320volts = 33%. Krutarth if you don't already have a watt/power meter you should consider purchasing one, excellent measurement tool to have in the kit so you can accurately measure your setup's current, and optimise your prop setup to fly with piece of mind that you are not over stressing motor, ESC or batteries.
Hi Sean, You can use a 10x5 APC prop on this motor with a 2S for sure, and a 3S will work but it will run a little warm if you're always heavy on the throttle. Don't use that prop with a 4S or you'll fry it for sure. Cheers, EA!
Would somebody please tell way to mount propeller on this motor using materials that are provided with motor? I mean how do i use this silver thing (bullet-shaped) to mount propeller on/in it?
Hi Krutarth, The prop adapter slides onto the motor shaft. It's a collet-type adapter which means the prop fits on the threaded shaft between the base and the bullet-shaped nose piece. The nose piece is threaded like a nut and is tightened by putting a thin steel rod (nail, drill bit, etc.) thru the hole and twisting. As the nose piece is tightened it causes the cone-shaped collet to tighten on the motor shaft which locks the whole assembly to the motor shaft. Cheers, EA!
my 3 cell lipo rating is 2650 ma at 30 C is that strong enough?
also i read somewhere about removing one of the wires from the ESC connection to the receiver/flight controller. can you elaborate on this please?
OK if you run multiple ESC's to a single receiver (or flight controller) you should cut the center positive (normally red) wire on 3 of the 4 ESCs to receiver. Some ESC's are OK with the power in parallel, but it but it can cause problems with switch mode UBECs, so for safety cut the center wire on 3 of the 4 ESC servo cables to the receiver. 2650 30c will give you 79.5Amps bit less than total demand of 4 D2830-11 motors at max amps.
vrwolf thanks for your quick response but i have another question...with the ESCs connected won't there be conflict on the receiver/controller since they all have to power the motors at the same time. for example, on an airplane there is 1 ESC that sends power to the servos when we move the sticks on the TX but with a quad all motors spin at the same time
1 thumbs up!
I have 3 of these total... two in a Multiplex TwinStar and one as a backup. They're fantastic motors for the price. I run 8x6 APC electric props on them (not the SloFly models, the standard electric props) and they always come down cool. 9x6 prop stressed them a bit. 8x6 was the sweet spot. Efficiency is awesome on these, too. I can fly for about 15 to 20 minutes and only use 1100mAh on my 2200mAh packs. Great stuff!
no problem yet. mine have 1.5h flight time now and still running strong. using lipo 3s 1300mah and a 9:6 prop, only need half trottle on my 1kg beaver.

1 thumbs up!
Tested this motor with a 10x4.7 slow fly prop, 30 amp esc and 3s 20c lipo battery. I was quite skeptical about this motor due to the bargin price. Anyway, here are my results:
180 watts and 18 amps
The motor gets warm at full throttle. Yet, I never need to use full throttle. This motor is powerful. It is also a smooth and quiet. My other motors aren't as smooth. My slow stick flies with a viciousness now. It gets up high in no time. The motor comes in a plastic case with a prop adapter, mount and information. The cost is under $8, yet it feels like a quality built motor which includes information. I curious to see the lifespan of this motor. Be certain to solder the bullet connectors on well or the motor will stutter like mine did. I had to re-solder the connectors again and it worked. I really like this motor!!
