I've made a 152" quadcopter using an Arduino nano. It flies nicely with a flight time of over 30 minutes. I've made a video log of the build that you can see here:

Enjoy!

 

Nice job.
So the 4 motors start from the same time and they controlled by the arduino when arduino got the signal from receiver?

Thank you! Exactly. And the arduino uses data from an accelerometer/gyro (mpu6050) to stabilize the quadcopter.

 

I have been building and flying RC models for more than 60 years and have to say, THAT is impressive. Very nicely done.

Receiver + 3-axis accelerometer/ 3-axis gyro (mpu6050) + Arduino + 4 Motors, how do the receiver and remote controller(transmitter)?

So you around 80 years old?

Thank you, that is nice to hear.

Sorry, I'm not sure if I got your question...

I was 9 years old and in the 4th grade. It was a J-3 Cub built from a Berkeley kit. Wing was 72", and power was something measly like a Torpedo 19. Controls used Babcock rubber-band powered escapements (2). It was a "bang-bang" system. One pulse was full right, two was left, and three was up. Rarely used down. They were basically power-assisted gliders. I built my first solid wood (pine) models like were used for IDFF when I was 4 (circa 1947).

I just described what the structures of your toy could be.

So your were start to play the flying toys at 9 years old, I didn't play flying toys only the kit of remote control ship used 4 batteries about 20 years old, when I assembled it had some trouble that it can't work, I measured it to tried to figure out where the problem was and I found the problem was in the direction control unit of the ship, I found that there were 4 diodes putted the wrong polarity, so I called the phone to asked the seller, the service girl said that they just wanted them to be like that, oh, I see, they must be afraid of other companies to duplicate their products.

 

Added a GoPro and some FPV-goggles. Hard to get the hang of controlling the quad at first, but after som practise it was a lot of fun!
