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!

Would have no other shaft for replacement or adptaç*ã*o the same engine? Or was some indication of an engine for model aircraft to 1kg and 200g 1m and 20cm wing?

 ElectricAussie 3009 points

Hi Carlos, Thanks for the credit. You should consider the D2836/8 1100kV motor (PRODUCT ID: D2217-8-1100) for that plane. It's a great motor and very affordable ($11.56). Cheers, EA!

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!

 ElectricAussie 3009 points

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!

 Mick P 206 points

I run the 10x6 and it works very well.

 ElectricAussie 3009 points

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!

 Mick P 206 points

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 :)

 ElectricAussie 3009 points

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!

Thank you very much for the valuable information!

 Mick P 206 points

Hi Paul, I have never tried this but it looks like it may suit PRODUCT ID: NTM28-ACC.

 Senator315 600 points

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.

 paul 16 points

senator those look great and mike p thanks u to for ur suggestion

 paul 16 points

also i dont think ntm ones work they only have three holes

 Mick P 206 points

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).

3,17mm prop adapter.

 georgiev.s 60 points

But there is propadapter in the package with this motor :)

 hermit81 1701 points

your shaft 3,175mm. and need to know diameter of hole in props. then choose need prop adapter

 Senator315 600 points

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.

Thanks Senator315

 Mick P 206 points

Motor side use the Polymax 3.5mm connectors - PRODUCT ID: AM1001A. On battery side with the Turnigy 3000mAh 3S you will need to use 4mm bullets PRODUCT ID: AM1009x10.

 Krutarth 7 points

Hi Michael, 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 ? Thanks, Krutarth

 Mick P 206 points

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 :)

 Krutarth 7 points

Thanks Mick P. :)

 Roger 2701 points

Yes Michael it will fit, the mounting Hole Bolt Circle: 16mm or 19mm corresponds with the motor mounts of the sk450.

 Senator315 600 points

You may need to mod the cowl a bit, but you can make it fit. Check the clearance in the cowl. HK says to use a 2226 on their 950mm one. I think it's too much motor for that plane though.

 veloci 78 points

My cowl is death and i made one myself so i can modyfi it such i will. So this motor will fit on it but with more power. Thanx for you answer

 Mick P 206 points

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

 hermit81 1701 points

normal config. props - 10x4.5

 Daniel 4 points

Go for a 3 cell battery, i use a 10x4.5 SF prop on 3 cells and it works great. I think a 2 cell setup would be very under powered.

 ElectricAussie 3009 points

Hi Alex, My pleasure! Your question above should get you the answers you need. Lots of details means a better and more detailed response. Cheers, EA!

 ElectricAussie 3009 points

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!

 Brian 14 points

* 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!!!

 ElectricAussie 3009 points

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!

 ElectricAussie 3009 points

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!

 ADRIAN 5 points

would this be ok with 30 amp ESC and 10x4.5 props on a quadcopter (Turnigy TalonV2) www.link

 ElectricAussie 3009 points

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!

 Mick P 206 points

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

 Krutarth 7 points

Thanks Mick P. I would be able to figure out almost all of my doubts.

 ElectricAussie 3009 points

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!

 Mick P 206 points

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.

 ElectricAussie 3009 points

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!

 ElectricAussie 3009 points

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!

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.
