Assembling the Frame

Installing a Pixhawk Flight Controller
  1. Of course Autopilots other than the 3DR Pixhawk or PX4 may be used, but these instructions can still serve as a guide.
  2. Place a 1" square of the Double-sided foam tape that came with the Pixhawk on the bottom of it at each corner.
  3. Adhere the Pixhawk to the top of the frame with the arrow pointing to the front (between the 2 red arms on mine).
  4. Drill a hole through the top frame plate near a frame arm near the edge on one side to accommodate the "safety" button.
  5. Also mount the buzzer on the top frame member on one side where it will not interfere with a receiver installation.
  6. Connect the 3DR power module to the Pixhawk connector and attach the power module out of the way also.
  7. Solder the other end of the power module wires into a battery connector along with the ESC battery leads.
  8. Install the ESC's signal leads into the Pixhawk (Main Out) servo connectors (signal wire on top).
  9. Install the GPS and magnetometer wires into the GPS/Compass module and the Pixhawk.
  10. Mount your receiver with double sided tape or Velcro on the top frame member to one side of (and not touching) the Pixhawk.

Installing a Px4 FMU / PX4IO Flight Controller
  1. Cut a 2" by 2" rectangle from scrap plastic or fiberglass to support the PX4.
  2. Drill 4 holes in the rectangle that line up with the mounting hole in the PX4 board (roughly centered)
  3. using 4 of the supplied black screws, mount 4 standoffs to the rectangle.
  4. Insert the PX4FMU board (connector side up) over the 4 standoff studs and (carefully) screw 4 more standoffs over them.
  5. Carefully fasten 4 nuts over the exposed studs securing the PX4 modules to the rectangle you made.
  6. Place the PX4IO board over the PX4FMU board so that the connector is aligned and push down over the studs.
  7. Place a 3/4" square piece of the Kyosho zeal at each edge of the "rectangle" between the standoff screws.
  8. 2FlamewheelsBuild/Flamewheel330PX4onZeal2
  9. Adhere the rectangle to the center of the top of the frame with the servo connector facing to the rear (between the black frame arms).
  10. Drill a hole through the top frame plate near a frame arm near the edge on one side to accommodate the "safety" button.
  11. Also mount the buzzer on the top frame member behind the PX4 stack such that it does not touch the "rectangle".
  12. Insert the power connector into the PX4IO board and solder the power leads and the ESC power leads to a battery connector.
  13. Connect the buzzer and "Safety" button leads to the PX4 boards.
  14. Install the ESC's signal leads into the PX4IO board servo connectors (signal wire on top).
  15. Mount your receiver with double sided tape or Velcro on the top frame member to one side of (and not touching) the "rectangle".
  16. You can make your own top cover from a rectangle of plastic or fiberglass (I used fiberglass, transparent is useful).

  18. Adhere the GPS/Compass module to the center of the top of the top cover (it doesn't matter which way it is facing).

Final Assembly
  1. Mount the battery between the lower frame sections and secure it with a Velcro strap inserted through the bottom frame plate slots.
  2. Route and secure the wires and cables with Zip Ties as shown to prevent snagging on the propellers or anything else.
  3. You need to leave a relief loop in the wires going to the autopilot, so the vibration isolation is not compromised.
  4. Ensure that the battery cable is secure but accessible to be plugged in when needed.

Setup and Additions
  1. Your F330 Flamewheel can now be configured as described in the DIYDrones wiki for Pixhawk (recommended) or PX4.
  2. For a PX4 set board and compass orientation parameters to "Roll 180" because it is installed upside down for connector access.
  3. There is space for a 3DR telemetry radio and / or an OSD and FPV transmitter next to the autopilot or the batery.
  4. With 9" props, the F330 can support a GoPro camera with a brushless gimbal and the necessary extended landing gear.
  5. I have had several crashes and only managed to break a few props.
  6. This little copter is very high performance, fully acrobatic, surprisingly efficient, extremely tough and it is a blast to fly.

Assembling the Copter
  1. Assemble the Frame components as shown following the same methods as described for the F330 Flamewheel Sport above.
  2. The illustrations included here for the FPV Pro can be used for assembly and wiring layout.
  3. 2FlamewheelsBuild/IMG_0389
  4. The above image illustrates the method for suspending the Pixhawk flight controller between 4 standoffs using O-rings.

    Setup and Additions
    1. Your FLIP FPV Pro can now be configured as described in the DIYDrones wiki for Pixhawk.
    2. There is space for a 3DR telemetry radio and / or an OSD and FPV transmitter on the side of the frame.
      • An FPV camera can be mounted on the lower frame between the slots in front of the battery.
      • If you use FPV keep it's transmitter and antenna well away from the GPS.
    3. The F450 is little copter is very high performance, fully acrobatic, very tough and it is a blast to fly.
    4. It is a larger than the F330 and a bit easier to learn to fly with it can also carry more and use a bigger battery and fly longer.
