@Satya bro IMO it will be fine. You have to consider amp draw by motor.

@Swapnil bro this is a tough work. Programming, debugging and testing would take so much time to make safe firmware. If you are completely new to multirotor, it's not good idea. Check rcgroups forum, it might help you.

Its will be around 13-15 AMPS (per motor) as per reviews adn the datasheet i have read..

Satya bro that's great deal you are getting GPS with it. More to say it's WKM at just 65 bucks. This will be sure in my wishlist but let's how review comes.

MultiWii 328P Flight Controller w/FTDI & DSM2 Port --> http://www.hobbyking.com/hobbyking/store/__27033__MultiWii_328P_Flight_Controller_w_FTDI_DSM2_Port.html
MultiWii Lite V1.0 Flight Controller w/FTDI --> http://www.hobbyking.com/hobbyking/store/__27109__MultiWii_Lite_V1_0_Flight_Controller_w_FTDI.html
MultiWii SE V2.0 Flight Controller w/FTDI --> http://www.hobbyking.com/hobbyking/store/__27108__MultiWii_SE_V2_0_Flight_Controller_w_FTDI.html
MultiWii PRO Flight Controller w/MTK GPS Module --> http://www.hobbyking.com/hobbyking/store/__26588__MultiWii_PRO_Flight_Controller_w_MTK_GPS_Module.html

Have anybody seen this? Now it's driving me crazy

HK has atlast realised what people want.
That FC is fine, but if you add ~$7 you'll get a CRIUS MultiWii AIO Pro (from goodluckbuy.com or rctimer.com). It has better sensors (MPU6050) as against the obselete ITG3205 and BMA180. ITG3205 has a low precision and is crappy, ITG3200 would have been better.
AND, Crius AIO pro supports dual firmware (MegaPirates) which enables GPS waypoints with the help of a mission planner! All these just at an extra cost of $7!!! (GPS module extra)

*programmability* MultiWii also has a GREAT GUI, which no HK board has. Add a bluetooth module and you can configure your multiwii using your android phone (that's not a piece of luxury, it comes into use at the field)
No more gyro pots, etc.

@satya:

Link 1: crappy gyros + Acc + baro + mag. Includes programmer. Not so good.
Link 2: A good gyro+Acc unit (MPU6050). No baro and mag = no altitude hold, orientations, etc. includes programmer
Link 3: Link 2 + baro + mag. includes programmer
Link 4: Ref. reply #284.

Update: refer all posts on the first page of http://www.rcgroups.com/forums/showthread.php?t=1726790 .
Most opine CRIUS AIO pro is a safer bet.

@satya: you're welcome.

Now when you have decided to make your own controller. Please check here
, to be honest i don't have knowledge to that level.
http://www.newbiehack.com/MicrocontrollerWritingthefirstprogramandtransfer.aspx
http://www.societyofrobots.com/microcontroller_tutorial.shtml
Please search over google, you will find many tutorials there. May be experts can give you direction to go further into this. You need deep knowledge of electronics and programming. Collecting data from receiver and sensors and process them sending them to ESCs etc looks simple but in practical it's one of the challenging task and problem is it's college project, you will have to complete within given timeline.

Need Some  more Reference who can help me in gujarat. Most probably in ahmedabad and rajkot. If possible then give more data and links here.. Can i use 8051 Controller? How ?

Multirotor fever can be seen now. HK has launched new multistar esc and completely new ready to use wiring harness for quad and hexa.
