Adorable PCB microcopter project on Instructables

From the Instructable:

Main Features:

  • X mode flying
  • MPU-6000 gyro & accelerometer sensor for flight stabilization
  • USB battery recharging on the transmitter, the copter plugs into the transmitter to recharge
  • When the copter plugs into the transmitter, the user can synchronize to a random radio frequency
  • Controlled using a Wii Classic Controller, which plugs into the transmitter
  • Running a modified MultiWii firmware, which is open source, written with Arduino and Processing

Dimension Specs:

  • Square center body is 1.5" by 1.5"
  • Propellers are about 45mm in diameter
  • Diagonal motor to motor distance is 110mm
  • Motors are supposedly "X-Twin" spare motors, they come with the propellers

Electrical Specs:

  • Flight battery is a single Li-poly cell, 3.7V, 350mAH, 20C
  • Controller battery is a single Li-ion cell, 3.7V, 1000mAH
  • Uses ATmega128RFA1 microcontroller for both copter and transmitter
  • This particular ATmega has a built-in 2.4GHz transceiver, 16 possible channels, 250kbit/s or 2mbit/s max depending on the standard being used.

Design Highlights:

  • The "arms" and "body" are connected by locking slots, making them easy to build and repair
  • Motors slide right into the arm
  • Two layer 1.6mm thick FR4 PCB used (this is the default for a lot of PCB manufactures), the components are all on a single side (easy to assemble)
  • All open source project, schematics + PCB + code all available. Heavy use of Arduino and Zigduino involved.

Anyone have RTF one to sale?

i think the fact this is on instructable with all necessary informations means this is a "do it yourself".....

Great project and innovative ideas.  I am amazed at the increasing use of PCB material for structural applications.
