Hi.. Im looking at buying the Sbach 342 EPP 3D Airplane 900mm. Would you mind checking my build? 1. D2830-11 1000kv Brushless Motor, is this a good motor for this plane?. 2. im planning on getting the turnigy dlux 30 esc. What prop would you recommend and any other hardware prop related? and what battery as well could you recommend?..TYVM
HK suggested motor is Donkey 33gram 100watt (fraction too small in my opinion for full 3D with reserve but it would fly for sure) or L2206A-1650 37gram 130watt 'good size', nice power to weight 130watt should flying 3D nicely maybe just bit high KV for larger prop/3D flying.
The D2830-11 is 28mm 52gram 210watt motor which is big for this 490gram model, it would be awesome power but CG maybe difficult. I fly a 675gram model with one D2830-11 and a 7x4.5E prop and it is very fast and has almost unlimited vertical.
Stick with a 22mm motor per HK suggestion. If you are looking for 3D power* consider the ADH300L Brushless Outrunner 1100kv, good power, good weight, low KV to spin a larger prop for your 3D flying. Any (light) 20A ESC with UBEC and light (80-90grams) 1000-1200mAh 3S battery 20C or better. Go with HK recommendation 9x5 slow fly prop and see what amps you are pulling at full throttle.
I have a 26 inch Nutball that weighs 530 grams I run it on 3s 1000mah and presently has this motor with a 10x4.5 prop 25 A plush esc This is the best combination I have used on this plane Unlimited vertical Motor runs quiet and cool delivers 800 grams of thrust and good flight times This is the fourth motor on this plane including the l2206a-1650 mentioned and is far better for aerobatics etc than the others Very happy with it
Like Hiko1 says you can try different motors and you will find the one that is sweet/suits your flying. The D2830-11 is a nice motor for the price but it is 28mm. Hope you get your model soon and let us know how it flies! Cheers Mick.
I noticed that there are 4 threaded holes on the drive end of the motor. Does that mean there is a prop adapter i can buy that bolts into these holes? Instead of using the clamp style prop collets
Let me help a bit. There is no such adapter anywhere (I mean, the bolt-on one). I've been looking for in both on HK and elswere, without any results. I ended up by using the SK3 series motors, which have the bolt-on adapter out of the box, as well as large (larger, then NTM series) bearings. They are metric, which means they are easy to buy (unlike the imperial bearings of the motor being discussed). I never worn out any, though.
But where does it say that max current draw at 3s battery & 10x4.5 is 21A? The only data i saw was for :
10 x 4 Current Draw 14amps,Power 155w.
Since i am using using the Turnigy battery, it says max curent draw is 30c (30*2.2/4=16.5 A per motor) so is there any reason why it would not work?
Hi Serang, With the motor rated at 210W, running on a 3S (12V avg) you would be drawing 17.5A (210W = 17.5A x 12V). On a 3S with a 9x6SF prop I'm drawing approx. 19A. as the 9x6 is a little bigger than the recommended size for 3S. Your 10x4.5 would draw about the same (18A-20A) because it's a little big for this motor on a 3S. You really need a larger capacity LiPo to run 4 of these motors. For a 6-minute flight at the 12A average power consumption per motor, you would need a 4800mah/3S LiPo.
While your calculations are valid, in real life 6min with a 4800 3S is not. I run these on tri's quads and Hex's. On a quad (~800g AUW), a single 2200 25c nanotech with normal flight will give you 9-12min, for acro 7-8min. 2 of these same batteries on a HEX (~1.3Kg AUW) gets around 12-14min. This is all with 9047 props. 8-9" props are ideal for this motor on a multirotor. You have to think about the way a multirotor is flown, which is around 50% average throttle over a flight.
Hi Senator, I didn't see any quad guys giving him the info he needed so I jumped in where I probably shouldn't have. I'm not a quad guy, but was basing my numbers on how the motor performs on 3D planes. I didn't realize there would be such a dramatic difference, but I think it's because of the lower weight loading per motor on quads. Thanks for giving Sarang the correct info for his quad. Cheers, EA!
Hi Nikhil, This motor is a little too small for the set-up you described. You should have a look at the D2836/8 1100kV motor (PRODUCT ID: D2217-8-1100). It's a perfect match for your prop/LiPo/ESC. Cheers, EA!
Hi Ivan, PRODUCT ID: KDS-20-L will work as a replacement shaft. You just need to file/grind a small flat spot for the setscrew to seat against. PRODUCT ID: OR002-01203 is a great prop adapter for this motor, much better than the one that comes with the motor. Cheers, EA!
Hi Andrej, Thanks for the credit. No connectors come with the Plush ESC series except for the little connector on the Rx lead. You will need female 3.5mm connectors (PRODUCT ID: AM1001A, 10 M/F pairs for $1.79) for the ESC's motor leads and a connector for the battery lead. Cheers, EA!
I measured the no load and resistance, then counted the poles. Not all motors will be exactly the same, but they should be very close to this apart from the poles which will be the same. eCalc doesn't have this exact motor.
I have one of these as a replacement for a similar motor
It is very smooth runs quiet and cool on 10x4.5 prop and gives me longer flight times on 1000 mah 3s battery than previous motor [not one of these]
can i use this motor (D2830-11 1000kv Brushless Motor) on this setup?
-10x4.5 carbon fiber props
have any one use/test the same setuo?
how much weight can they produce in that configuration? what will be the output watts and amps? thanks
I'm currently using D2836/11 on a quad running 10x6 3 blade props. Good performance and about 12 minutes flying time with a 4Ah 3S LiPo. Building a hex which will be a little heavier than my quad (1600g up from 1200g). Would like to swing same props and looking at the D2830-11, the D2836/11 or the D2836/8. These D2830/11 certainly are a bargain but I'm concerned about heat. Inputs?
I am having serious problems with those motors. Ordered 5 of them for quadcopter and 3 of them are running so out of true that it is almost visible with naked eye. I am not able to balance them using laser method (props are already perfectly balanced), so I am getting really frustrated. Any ideas what can cause such massive vibrations? Bent shaft? Can I get a replacement shaft for this motor?
Hi MasterB, What you've described is much more likely to be a problem with the prop adapters that came with the motors than with the motors themselves. I own several different Aerodrive series motors and the machining, bearings, etc. on all of them is near perfect. The aluminium prop adapters are another matter altogether. I have a motor parts box with a dozen of them in there because they're cheap and nasty and not worth messing with. Order PRODUCT ID: OR002-01203 ($1.78 each), as these are very high quality and precisely machined adapters. Cheers, EA!
Hi MB, If you bought all the motors at the same time and you're certain the motors are out of true then you were unfortunate enough to have gotten a bad batch which is rare for this series. I run 4 different sizes on various 3D planes and have yet to receive one that didn't run perfect straight out of the package. My D2822/14 has been used daily for almost a year, getting crashed and thrashed along the way, and it still runs true. Don't give up on these motor, as they are so cheap you should order 4 more and keep the first 5 for scavenging parts from. Cheers, EA!
I have around 30 of these and use them on my tri's, quads and hex's, never had an issue with any of them. You are either very unlucky or there's an issue somewhere else like the mount or something. I'd recommend these motors to anyone any day of the week.
I also find the supplied prop adapters with the D2830 and D2826 are not always true or balanced, 1 prop adapter out of 4 was OK for me so far. I now replace them with 3rd party prop adapters and they run sweet and balanced!
I have 5 of these motors, the longest running for slightly over a year now. It has went through many nose-in and through mud and water. I always rinse the mud off using clear running tap water. Still works to this day. So, as a conclusion, I dun tink need any lube! Use if u want, no guarantee!
Not running hot when installed properly.
I found out why the motor was getting hot! The test mount I had it in when I was running it completely blocked all the vent hole on the back side of the motor. That's why only the back half was getting hot. It's not a problem with the motor but a problem with the owner.
Michael, I'm getting the same with a 3300 3s 30c and 10.45prop. 175 Watts 17 amps max. That's fine with me. It give you a margin of safety. That's plenty of thrust for your average Quadcopter.
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.

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!!
