i will be using coreless motors of around 48000 rpm in my quadcopter. the frame will be made of bamboo sticks or similar light weight objects.
i want to know if only one esc will do the trick for me.? i will be using CC3D as my flight controller and i want to control it using my android phone, is that possible?
and can i use batttery from my mobile phone to power the copter?
it is going to be a mini copter and very lightweight, so please consider these things and reply

You can ask Satya sir for any further help.

You can't drive coreless motors off a CC3D as the CC3D is meant for use with brushless motors and ESCs and so outputs a PWM signal meant for the ESC. You also can't drive 4 motors off a single ESC. You need a brushed ESC for coreless motors. Using brushed ESCs on a quad this size is total overkill. A better choice is a brushed flight controller like the Scisky/ Quanum Pico or the new SPRacing F3 Evo Brushed board. You could also use something like the CJMCU frame + flight controller and a Bluetooth module to control it from your phone. Take a look at this: http://ez-gui.com/other/cjmcu-quad-and-ez-gui/ The problem with these small brushed builds is that it is difficult to get batteries for them. I doubt your phone battery will be able to supply enough current.

could you please elaborate on use of this spr racing f3 evo board and also the above video is basically has everything that i hv planned. could you please tell me which fc board i should buy because the video has not mentioned it

thanks for the video. do you know the board used here? it would be of great help if i can know the name of the board!

This is the board used in the link I posted. The other board I mentioned is the SP Racing F3 EVO Brushed. It may be good if you are building your own frame but I don't know for sure if it supports bluetooth control (though I think it should). It is also a brand new product, still on preorder so the quality is still unknown.

That is WL V939. That board is obsolete now. Anyway Wl V939 board is compatible with flysky protocol.

also, this guy doesnt seem to use any ESC for the motors. can anyone please explain why he did that?

SK1701 that has the frame too. but i want to build my own frame and use a flight controller. can u suggest any good but cheap FC boards?

No it isn't. It's an STM32 based board that runs Cleanflight. It also does not have any integrated receiver.

You don't need ESCs as the board has built in FETs to drive the motors. Most brushed boards have that.

I don't have much experience with brushed quads you could use the SPRacing Evo Brushed board I posted a link to or the Micro Scisky board.

i have a KK2.1.5 mini multi-rotor lcd fc board available here. (link-http://robokits.co.in/quadrotors-hexarotors-drones/flight-controllers/kk2.1.5-mini-multi-rotor-lcd-flight-control-board?zenid=3pmoav1js6skqunn1f8ifd5l72)
can i use this?

@SK1701 tell me sites from where i can get the flight controllers. the names you have mentioned are all available on banggood or hobbyking sites which are US based. just guide me a little bit more.

First go on rcduniya.com, on the home page you will see all RC resellers and sites. Also use rcduniya like RC search engine 😉😜

can anyone tell me how long do those motors last?
i mean after how much time will i have to replace them with new ones?
