Frame Construction

The original frame construction can be found here. The following are some shots of the latest version of this frame built for the AeroQuad.

Connect the four arms of your quadrocopter using a 1/2" PVC 4-way connector. Use a Dremmel or similar tool to drill out the middle of the 4-way connector. This will allow the wires from the motors to be fed into the middle of the quad frame.

The arms used are T-REX 600 tail booms. The best are the aluminum ones (carbon fiber is too expensive with minimum weight savings). You can also select different colored ones to denote which is the front and back. Cut to your desired length.

Using 3/4" aluminum C rails, cut mounts for the 4 motors and 2 for the front / back landing gear connection points.

Pre-drill holes for the 4 motors. (I accidentally went drill happy and drilled more holes than needed for this picture.)

Flip the quad frame upside down and put the motor mounts on the 4 arm ends. Since they are lying on the floor, you will naturally get the 4 mounts level (assuming the floor is level). Tape them in place and drill holes through the mounts and the tube arms.

Use #6 1 1/4" screws and nuts to hold the motor mounts in place. Do the same thing for the landing gear mounts.

Mount an electronic project box by drilling a hole through the 4-way fitting / each tube arm / battery mount plate / project box. Drill a hole through the middle of the project box to allow wiring from the motors to reach the ESC's inside the project box.

The landing gears are from a T-REX 600. Use the version specially for the electric version of the T-REX 600 as they stand higher than the gas version. The next version of the frame should drill holes through the arms for the motor wiring, such that the motor wires don't feed in through the outside of each arm. In case of a crash, this should prevent any accidentally cutting of the motor wires (although this hasn't happened to me yet).
