I've been doing a lot of research about this and I have not been able to find a proper tutorial that clearly explains how to use an android phone to control a quadcopter.. what I mean is to change a transmitter and just use an android phone and Bluetooth to control the quadcopter..is this possible to do?
if it is.. please share some advices as I am planning to building a diy quadcopter that can be controlled using an android phone through Bluetooth.
thanks!
Yes, it is possible, hazardous, complicated, and if you have to ask, you ain't ready to tackle it. WiFi, not Bluetooth.
This how almost every consumer quadcopter or hexcopter is controlled. Usually via wifi, since bluetooth doesn't have the range. Quadcopters and hexcopters like this are readily available nowadays (at least in the US).
But do you know any tutorial that would explain how to do it?
I'm not really looking for range right now.. I just want to know if its possible to do it and what is the way to do it?

You want to build an expensive quad-copter using hardware that you KNOW won't work. Why? Minimize the frustration by starting with the right hardware.
Bluetooth is NOT the right hardware.
I know it is not but I've seen people do it...It is possible to do it
I just don't know where to start
I got as far as to turning the motors on and changing the speed
Now I want to know how I would be able to control them

Great. Show us the code and a system diagram.
Schematic with MPU 6050.. how do I use MPU 6050 to control quadcopter orientation or atleast auto level it when I release the control buttons?

Wherever you got your schematic from should have working code which apparently is in your previous code.
So I am not understanding your problem.
If you are expecting full working code, you had better be prepared to pay for it. I certainly wouldn't be giving it out free.
I made the schematic and the code..
the arduino pictures and the esc and motor pictures on the schematic are from Google I just put them all together.
Also, Im not expecting a full working code although that would be nice to have
Im here asking for help and to learn how this would be done because I've done enough research and not one of them explains clearly how this can be done properly
The first thing you should learn is how to post code in the forum properly. Read the sticky post, first one. Then go back and read reply #1 again.
I know how to post codes.. I just don't have the .ino file itself because I'm not allowed to download arduino on my work computer.
I just wrote the code from memory

You definitely don't know how to post code. Trust me. Go and read the sticky post. It involves using code tags. If you really wrote from memory you should have told us that.
Happy?

I am curious of the hold in place loop when you ...
it will add a whole new level of excitement to the activity.
