These are the same motors .The main difference between them is TURNS AND AMPS.
So what is the difference with NO. OF TURNS OR AMPS.??

I have 11.1 volts battery and 30 amp esc.

can we operate this motor
http://www.hobbyking.com/hobbycity/store/uh_viewitem.asp?idproduct=12919
on 30AMP esc ( http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=13429 )?

Thnks

The motors may look same due to the stickering but are different, rc brushless motor are defined like this ABCD- X Kv

this mean AB is the diameter of the rotor and CD is the magnet length, X kv is the rpm/V, longer the magnets, higher the current and higher the Amp

A motor with more number of turns will turn slower, and with a high force so so it gives higher "Thrust" and  motor with less number of turns will faster with less force and gives you "Speed"


Nope u cannot operate http://www.hobbyking.com/hobbycity/store/uh_viewitem.asp?idproduct=12919 motor on that ESC as its Max current is 34 A

What bout this one?anyone used this one.

just curious to know how u are choosing a motor for ur airplane?

This motor http://thehobbyshop.in/index.php?main_page=product_info&cPath=10&products_id=31 is way to small compared to one u asked in 1st post.

Actually friend i am a begginer and i dont have time to research on motors coz we have science exibhition in our school next month and i wanna participate with plans.

http://rchobbyaddict.com/product_info.php?cPath=53&products_id=144&osCsid=566fc2a40f190ea4fb2dfe38d9808df2

I saw that its weight is 44 grm.So i thought that it is a medium sized motor.

Found one more
http://www.rcbazaar.com/products/123-aeolian-c2830-kv1000-brushless-motor.aspx

ohk! lemme sort it out for u then, how much does ur airplane weigh ? wat the maximum width of ur airplane? and wat electronics do u have right now with u ?

This should read as "torque". Thrust is determined by a combination of prop diameter, pitch and RPM.

  my bad! tats torque, layman's term thrust!

I only have informations regarding rc and i am buying some electronics today or tommorow.I will be using an Airtruck
http://rctestflight.webs.com/airtruckinstructions.htm

or

http://www.mikeysrc.com/FPV-Pusher-Plane.html

So just need the combination of motor ,esc,battery.
motor i have selected is

http://rcelectro.com/index.php?page=shop.product_details&flypage=flypage.pbv.v5.tpl&category_id=2&product_id=92&option=com_virtuemart&Itemid=2

and esc will be HK 30 amp.

these motors are very in efficient and draw amps than quoted by HK though they have power but very bad efficiency

So akky could you please suggest any motor? 1000kv  for airtruck or Mickeys FPV plane (posted the links above)  

Accha Hk6ch black 2.4 . Kitna mw (power)??

Airtruck would be better!

Assuming ur airplane will weigh less than 600g

Motor :http://rchobbyaddict.com/product_info.php?cPath=53&products_id=144

Esc http://rchobbyaddict.com/product_info.php?cPath=24&products_id=91

Battery : http://rchobbyaddict.com/product_info.php?cPath=25&products_id=115

wat about ur radio, and servos??

I have HK6ch black 2.4 and will buy HXT 900

Thnks jatayu .you are very supportive.

wel both the ESC's are good,

one in HK is backordered so not sure when it'll reach u, and will cost u around Rs 670 including shipping

u can buy it locally assured shipment, no waiting worth paying  Rs 100 more

since its pusher first of all///and your spinning a large prop  i suggest you to use a powerful 1000 Kv motor

@jatayu
From where can i get Turnigy plush 30amp in Rs 670+100 ?? any links?

On HK website i saw that orders for Turnigy plush 30A were -16 !!
That means more people are willing to buy it coz its a good ESC.
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=2164

But this HK ESC
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=13429
is the same thing but less cost and 3gms more weight than Plush.
feedback of customer is also good on both ESC's .

But -16 orders for Plush is attracting me towards it .

The weight is with out connectors so it will increase by atleast 20-30 grams,

if u are willing to wait, u can proceed and buy it....

i jus meant that it is available locally if u are ready to pay 100 or 200 more....

Be aware that HK will not publish negative comments, and also positive comments will give them store credits.... hope uunderstood.
