I have this motor on my fpv sirius with 7x6e 40A plush esc and 2200mah 3s works great. Im not sure about a 3 blade prop.

I need more trust~1200~1500gr than my stock setup: 1400kv ~ 180w 8*4 2 blades prop and 800gr?

 mikec@aloha.net 220 points

you'll burn it for sure with a 8 inch 3 blade. if the motor was a 1400 kv sure.

 David 47 points

ok. How about 8*6 2 blades?

 mikec@aloha.net 220 points

well using a 7 inch blade works even if it say 6x4 with 4s. the motor gets a little warm with a 7 inch blade. of course it depends on the pitch too. an 8 inch will be too much no matter the size of the pitch. do you have a meter to measure watts and amps? you can check the numbers of an 8 inch if you need to see. usually if a motor specs say 6x4 prop, go an inch smaller like a 5 three blade prop. i would say check it out for yourself. but for sure any 8 inch 3 blade even 2 blade will burn the motor. good luck

 mikec@aloha.net 220 points

David, keep in touch as to your setup and what you decide to do. if the motor kv was like 1400, you could swing an 8 inch prop. still depend on the motor, brand etc. i'm going to order this motor and use a 7 inch prop 3s 40c lipo on my bixler2. at some point i'd like to do fpv. an 8 inch prop would be great to carry more gear. hopefully hk will have another motor with a 1400kv. cheers

There's not really an average, it depends on what prop your using, have a look at the prop test's above, they are only for 5inch and 6inch props and not all props are created equal, flight time depends on your flying style (how hard you are on the throttle), maximum power of this motor is over 400watts, I would be looking for a larger ESC 40-50amps, the original motor was around 130watts, your putting something like 3 times more power in a bixler2, I hope your ordering the 4mm carbon rod to strengthen the wings, your choice but I would be looking at Turnigy D2826 2200kv that's only 300 watts and a 7x5 prop, and I would still get the carbon rod!

 Ral fRotten 1068 points

Great video, have you put an amp meter on that with the 7x6 prop, I would love to know thanks.

 srepfler 1111 points

Yes, on 2200 3s with 7x6 40A and 400w with no problem. Have a 50A ESC.

 Ral fRotten 1068 points

Thanks for that, sounds like a good combination for a skywalker falcon, thanks again

 David 47 points

Hi guys! I use 25amp plush 2200kv 2836 tg 3000mah 40c nano and 6*5 tgs sport prop on my black falcon, i can say he fly like rocket and scream like she..almost) so fast

 David 47 points

sorry 2826

 JiaCheng 23 points

Try the D2826-6 2200kv. This one is WAYYY too overkill

 red25 116 points

why do you need to reverse the shaft? you can use this PRODUCT ID: NTM28-ACC to mount it as a pusher.

 red25 116 points

i only fly it on 40%to50% throttle it is enough to fly my fpv sirius at 50km/hr ground speed. and yes it gets hot after 20mins during take off i apply around 70% throttle.

 jps123 44 points

there is a table on the description with the amp draw of this motor when you use a specific prop size.

 red25 116 points

i use a 7x6e on my sirius on 2200mah 3s with a 40A plush esc.

 Ltomi78 43 points

HI Red25!

I test it only on ground max speed with 7x5E APC prop. Its became hot after 1 min continous full throttle is it normal?

This is brushless as indicated by the 3-motor wires in the picture. Brushed motors have 2 motor wires.

 NewToHobbyKing 6318 points

DAJARAJA some one has made a mistake here. So do you wish to report it to HK, using the Blue Issue Tab above or shall I. Also sorry about before. My fault we, both know it works. SORRY.

 DAJARAJA 294 points

Hobby King 2.4Ghz Receiver 6Ch V2 .nth you have a silver tongue,but that dose not change the truth.you made that question about you and i and i took the bait, but you missed the point(or chose to ignore it)so here it is a again .members and customers post their questions to get the best possible answer or answers, so on a recomendation (if taken)will make a choice.in doing so ,they will spend their money( let me repeat) they will spend their money on our replies.as i said i would not like to give advice on a subject if i didnt know for sure ,it has to do with my 1)integrity and honesty 2)members advice that i have taken ,which in turn has made my rc experience a happy one .if you would like to know more about who i am,read my reply to 1 of our members and look at the date ( hexTronik 24gram Brushless Outrunner 3000kv ).as i think many will agree. yes i red your last reply .saying sorry for your replies and nothing else really just shows your character.so i will choose to ignore your answer to the above question and just ask you to stop being a bully by putting words into my mouth that are not my own.nth just leave me alone and lets just say we agree to disagree and i would just like to add ,a big SORRY to everyone that i have gone off subject with the item concerned above .

 Ral fRotten 1068 points

DAJARAJA amps = watts/volts, so if the motor is rated at 438watts, 438/11.1volts (3s) = 39.5amps or 438/7.4volts (2s) = 58.5amps!, or 438/14.8volts (4s)= 29.6amps,... what propeller and battery you use will determine the amps,.... their prop tests above look ok to me,... I would buy if you hav'nt got one already is an amp meter, and try with your setup to keep it around 30amps. the prop test above for 11.1volts looks like you could run a bigger propeller easily to lift the power up, That 55 amps is the maximum/burst current, so as long as you don't keep it there for long it should be ok, I'd aim for around 30amps then your ESC is cheaper too! .....................my calculations are for running at full power, ie 438watts, I would not advise using 2s on this motor.

 DAJARAJA 294 points

thanks for your reply Ral fRotten,easy calculation.no i dont have a watt meter(im buying 1) and their was not enough info(reveiws) for 4s lipo to make a decision on prop size /esc /static tests.the specs were also confusing me.just wanted to know i wasnt going to burn the (35 amp stock esc on plane this motor is recommended for).i am confidence now with info given from you and others to fly this plane with this motor/6x4 prop and have also learnt simple cal for working out watts thankyou. happy flying

 Ral fRotten 1068 points

Yea the old formula, W=VxI, comes in handy, With your 35amp esc I would still be wary of sustained WOT at 4s, and get a amp/wattmeter to check the real world current draw, theory is good but a meter is better!

 DAJARAJA 294 points

cheers mate i hear ya,good advice thanks again.

 New123 13 points

Does it fix with the motor mount? or you have to mod. what is the speed or around?

 Carlos J 151 points

Im not shure of the speed but its fast enough for the airframe , i ended up clipping the wing tips because there was too much flex even with a solid spar . This motor will allow it to fly at 1.7kg easy and if your good you can fly in high winds no problem. This dude down the road seen me flying in high winds and took his bixler out with stock motor launched it and the wind blew it away like a piece of trash, never found it again. haha poor young fellow. The NTM range of motors are the best value for money , best motor for bixler bro.

 New123 13 points

Thanks Carlos J gor yoour reply

 houthakker 9 points

well that depends, use a 7x4 2 blade and it will draw 29~30A with that setup. ESC rating 30A usually means peak power, it will handle the setup but keep in mind not to fly full throttle all the time. For a 3 blade setup you need to upgrade your ESC.

 Leologic 1 points

Thanks Thakker, What about 40-50A esc with 3 blade prop on this motor or should I go for 1400Kv motor for more thrust as the wt of the model is 1.3 kg.

 houthakker 9 points

I would not recommend a 3 blade prop on this motor, as it will burn the engine. The engine can only deliver 438 watts and to spin a 7 inch 3 blade prop you will need a lot more. go for the lower KV motor and make sure it can take at least 40 amps

 electrorocketeer 30 points

yes, this is the motor you want for x5

 alpha-madman 36 points

hi ,ive burnt 2 of these with 7 in prop on 4 cell , stay at 6x4 or it will toast it ,i love the power of this motor thou .1800 ntm 6x4 . 2200 ntm 5,5x 4.5 or motor gets hot

 srepfler 1111 points

Yes, to much on 4s, but on 3s with 7x6 you got around 400w and 40A.

 mikec@aloha.net 220 points

it would work for both bixlers. better used though on bixler 2. for the bixler 1 i have a 2200kv 2836. awesome power.

 srepfler 1111 points

Yes, but put recommended size prop.

 Gary 2958 points

Yes,will be ok,it is on the limit of what the motor could draw but should be ok as long as you do not over prop it.

 Yanik727 3 points

Ok thanks Gary!!! Now for the lipo, is it ok if i use this one? Turnigy 2200mAh 3S 30C Lipo Pack
and Turnigy nano-tech 1300mah 3S 25~50C Lipo Pack ???

 alpha-madman 36 points

no .u need 40 esc on 3 cell and 60 on 4 cells or thermal protect kicks in and servos quit working (with no bec)as u will prop up , everyone does .lol

 Gary 2958 points

Both will give you more than enough amps so yes,you can use either.

 RC Wolf 8 points

I am also looking at this option for Bixler 2. People are recommending the Turnigy 2200kv, but it seems to me to be over too much power at a high energy (flight time) cost. Will this motor fit directly on the stock mount?

 RC Wolf 8 points

I am looking for a mid term 1800 kv for my B2. Any suggestions?

 RC Wolf 8 points

Will this motor work for the B2? Maybe a dumb question, but it seems to have the power cables comming out from the opposite side of the stock motor.

 RC Wolf 8 points

Not sure about the connectos. Does anybody have one installed in the b2?

 bananabender 129 points

i put the 2200kv version in my bixler2 the wires are a pain dont even try drilling out motor mount to pass them through is to hard , i ended up cutting the foam just continue the line of actual bixler along top where motor mount is to cut etc , then you have to grind out a little foam for wires behind motor mount then use some epoxy and put it all back together makes for stronger motor mount as well im still to fly mine but it looks solid

 RC Wolf 8 points

Please give us your view on this motor for the B2. By what I´*ve been reading, it may be too much power at a a high flight time cost. Tell us how much time you get out of your battery.

 Gary 2958 points

Which model are you thinking of using it in?,it is quite a high revving motor and swings a small prop so is it a pylon racer or something quick like that?

 Edwin 12 points

I use a 4 cell, 1000 mah 30c Turnigy Batt. Dont go less than 30c on this motor. Good motor.

 Gary 2958 points

Should be fine on a 3s,would not put that prop on a 4s battery.

 Edwin 12 points

Yes, I have run this motor on a 6x5.5 prop and 3 cell in a Funjet.But dont go bigger than that. I put a 4.7x4.7 with 4 cell.

 klaw81 87 points

You could, but it wouldn't work very well. You need slower motors and big props for quadcopters. You should be looking in the 700-1200kv area.

 klaw81 87 points

Higher-kv motors are not good for multirotor aircraft, especially heavy-lifters. You'd be much better off with the 1000kv version.
