Hello every1. I want to build foamy B-25 Mitchell: total weigh ~1.5kg. I want to use 3s batteries and of course two motors. I found nice 8x6 three-bladed prop from master airscrew (ID: MA0860T). This setup should give me ~1kg of thrust per motor and it is enough. I have few Turnigy Plush ESC 30A (40A burst) and the cheapest way for me is to use my old ESC's rather than buy a stronger one. What do you think guys? Will it make?
Could you tell me please something more about max current with 3s battery and some props like: three-bladed 8x6, classic 9x6, 10x5 or similar? I'm asking about values from real ammeter - not from theoretical calculations.
Hi! I have FPV Raptor and put on his 9 inch prop without modification does not work, but the engine will approach and three bladed propeller will give about a kilogram of thrust. I bought my plane's this motor ID: SK3-2836-1500 8x6 propeller
For those interested in using this motor here is my setup. My quad weights 1.6kg and I have added 2 more steel bearings per motor as per file photos. 5000maH 20C 4s, 18 amp t/plush with 10 inch 3 blade props. Hover is exactly 15 minutes using 4.85 amps per motor. Not sure how long the steel bearings (and if it is actually having a negative affect) will last but will try ceramic bearings and post later. This is no sports quad, but a great platform for FPV and video. Great little motor!
do you use the prop adapters that come with those? I have the problem that no matter how tight I screw the prop on, at one point they just fly away... My quad weighs about 1.4kg AUW and I use 10x4.5 SF props.
Yes I do. I just tightened them with a drill bit. No bonding liquid. I did try the grub screw adapter but the hole was slightly bigger than the 4mm. (4.1)You do bring up a worrying point though. Maybe you are pulling the max amps quite often?
Hi armen, Look at the menu along the top left side of any page on the HK website and you'll see a menu item called "Multi-Rotors & Parts". Click on that and you'll see a drop-down menu where "Propellers" are listed as one of the choices. Click on that and you'll get the complete list of props suitable for multi-copters. Cheers, EA!
Just choose a battery that's right for your application. The extra cost of the higher discharge rate lipo doesn't really appeal to me. I'd rather buy cheap lipo that will give 90-120% of the required current of my setup. Aiming for too much is just a waste of money.
What size battery mAh should I use with 14.85 volt with 7*3.5 with 4 motors of this kind
With the normal required weight for all component together .? Does the battery amper effects only on flying time or on the thrust too? I know I'm giving complicated question but I don't want to jump and do something blind , question and answer approach is beneficial and you seem to have long time experience of this field .
If you take a look at the max current rating of this motor, it says 18A. If you use 4 motors for a quad, that is 18*4=72A that is assuming you don't overload the motor and you keep within limits. The lipo you need should be able to supply at least 72A of current, but that is at maximum. A 2200mah 40C lipo can provide this amount of current for you (2.2A x 40 = 88A). For sure it will fly with just a 2200mah 20C lipo but drawing 72A continuously from such a lipo will result in overloading and it will eventually puff or heat up.
Thanks for the answer , I have another question , this motor label Prop size: 7.4V/11x7 14.85V/7x3
But the problem is there is no CW CCW propellers with those two sizes , I bought the motor and all the component to build quad copter except the propellers , unfortunately it is hard to find those propellers for quadcopter . Any recommandation to me , which prop should use that equivalent to those two different props.? Two produce the thrust that written above .
11x7 is recommend for 2S 7X3 if for 4S, what lipo are you planning on using it for? IT was not mwnioned but for a motor this size and kv, a 10x4.5 prop also works well at 3S. Which has plenty of CW and CCW matching props.
Hi, I've bought 4 of these Turnigy motors and also bought 4 NTM 2826 1200kv with 4x F-30A HK ESC for my quad frame X650F. Which motor set would suit this frame better to lift a camera and gimbal? Which has better quality and reliability? Turnigy or NTM? Also, what sort of flight time can I achieve with a 3s 3600mAh? Thanks
I almost finished a quad build with those motors on a HK X525 V3 frame with BLHeli flashed 18A Turnigy Plush ESCs and 10x4.5 SF props on 3S. So far it seems to be just fine. However, I'm not sure about how well the D2836/8 are balanced. A short first test without props showed some vibration but I'm sure I can fix that somehow...
your absolutely correct, the collet never fully covers the shaft as in a crash only the shaft will bend(worst case), but closer to the motor will damage the motor can in a crash, these do have three threads on the front but no prop adapter, search dys motors as they are the maker of these
How about 4 of these motors on a quadcopter? I will use 30A esc's but not sure about prop size (want to be around 20-22A), and any idea of the thrust it will give? (I want to lift a gimbal with camera too)
I use 4 of these on the quads I build using HK-SS30A ESC and 10x4.5 props. Thrust with this setup calculates to about 2.3kg ... not sure what your frame weighs but I would think this would work just fine for you. Also, this is drawing about 17-18A at motor maximum.
I have already replaced the bearing of my motor. This motor has 2 bearings. One has internal diameter 4mm (for the shaft), external diameter 10mm and a width of 4mm.
The other bearing has internal diameter of 4mm also, external diameter 8mm and a widht of 3mm. The first one can be found with the denomination MR104ZZ and the second one MR83ZZ. Any good bearing supplier can help you with this parts.
How is this motor rated at 336 watts? Clearly states 18 amp max current and 15 volts max
Watts = Amps X Volts........270 watts = 18 amps X 15 Volts
No "burst" current is identified, though I take a "max" rating to be just that. You would have to push that to 22.4 amps (fully 25% over max) to see 336 watts from 15 volts.
Hi Scottrik, The 18A max current shown in the specs is nonsense. If you have a look at the manual in PDF format under the "FILES" tab above you'll see more meaningful numbers. The motor draws approx. 25A on a 3S fully loaded, which is close to the rated 336W (25A x 12V = 300W). Doesn't run hot and hasn't shown any signs of deterioration. Cheers, EA!
Hi aussie, How about t4 of these motors on a quadcopter? I will use 30A esc's but not sure about prop size (want to be around 20-22A), and any idea of the thrust it will give? (want to lift a gimbal with camera too)
Hi Thomas, I'm not a quad flyer so I often get it wrong when I try to make recommendations on quad set-ups based on how I set up 3D planes. As far as prop sizes for this motor, it's comfortable swinging props up to around 10x5 on a 3S. If you use a 9x5 (or maybe a 9x6) I'm almost certain you'll be down around 20A-22A. Cheers, EA!
Wil prop with 3 mm hole fit in the adapter? Also, is this motor good with the turnigy nano-tech 2200 mah @ 3s and 25-50C?? HEre is the link of the battery and also the ESC im planning on getting with this motor:
http://hobbyking.com/hobbyking/stor e/__11911__Turnigy_nano_tech_2200mah_3S_25_50C_Lipo_ Pack.html
with that setup I'd use either an 8x4 or 8x5 3 blade prop. This should give hover around 51% throttle and about 7 minutes or so depending on weight ( I used 1550g as the weight ) and an efficiency of about 73-74%
