Please check the new version of this instructable: flone 3.0
Flone is a H airframe for flying smartphones.
Video of maiden flight:
It haves the place for a minimal setup:
* Android smartphone.
* Multiwii/Arduino flight controller.
* Mini Power Distribution Board.
* DSM2 Controller
* 4 motors
* 4 ESC
We enjoy designing it, it's well balanced and haves the space for a clear field of view of the camera.
The design includes a tiny Flone PDB integrating airframe and XT60 power connector.
Get updated with new improvements in the airframe and the Android App in the webpage of the project:
We plan to release the first version of flone software under GPL around the end of 2013.
The app for ly the smartphone is available in:
Step 1: Obtain Materials
You can download the flone dxf file in their thingiverse repository:
You'll have to look for a local or online store to purchase the materials. We provide you links to Hobbyking as a reference.

Step 2: Cutting the Airframe
If you don't seem to find one or you just can't wait, print the file in A3 paper and cut the wood veneer with a jigsaw.
Step 3: Assembly It
1 Glue the reinforcement arms to the main frame. (make sure the hole for the legs it's aligned so they will be able to stick in in next step)
2 Glue the legs
3 Once everything dried up, fit the engines in its final position and fasten them with cable ties.
4 Remember that cyanoacrylate and cable ties are the best friends of the dronistas. The cable ties brake before damaging the precious propellers or move the motor shaft. If you can't use them you could always use model airplane glue.
Step 4: Attach Flight Controller to Electronic Plate
Regardless of the flight control board you have chosen, the placement is always the same: in the center of the bottom bracket. It is highly recommended to glue the board with the sponge to isolate it from the vibrations of the plate.
We are using a MultiWii of 10 degrees of freedom, but you can choose any other one.
Step 5: Solder Flone PDB
Step 6: Attach DSM2 Radio to Electronic Plate
Step 7: Flight Control Board Configuration
Check out that you can arm the motors and that they will consistently respond to the movement of the aircraft if you try to bend it in any direction.

Step 8: Connection of the Engines
To connect each motor to its ESC start connecting the 3 cables randomly. Now connect the ESC to its corresponding 3 pin connector in the flight control board. Connect the battery to the PDB. Switch on the RC and power up the motor. Check out the rotating direction against the draw in the arm in which the motor will be placed.
Repeat for the rest of the motors. Make sure you got it clear before welding the connections.
Step 9: Glue the Sponge & Ribbon for Vibration Isolating the Smartphone
2. Next, tighten the ribbon around the sponge and the main frame and glue its extremes into the main frame's opposite face.
Step 10: Screw the Electronics Plate
Cable tie the ESC and the cables to the main frame. Just keep in mind to leave enough room for the leg's protective foam.
