Cut two 1-1/2-inch pieces of rail and glue them in the front of the case as
shown. Center them 3-1/2 inches from each end. These are the backing for
the screws in the chest latch.
Place the Phantom in the center of the case. Cut eight 1-inch pieces from
the rail stock. Glue a block in the case at the end of each landing gear
in four places. Leave a little clearance. Now glue a block on the side of
the gear, near the end block, in four places. These blocks will keep the
Phantom from shifting in the case. Next, drill a 1/4-inch hole on each side
of the gear in the center. Draw a centerline on a scrap piece of plywood.
Hold it under the 1/4-inch holes, sighting through them to see the
centerline. Now match drill the 1/4-inch holes into the scrap piece. This
will be the hold-down bar. Clean it up after the holes are drilled. Install the
1/4-inch bolts from the bottom, thread on a 1/4-inch hex nut, and tighten.
Install the hold-down bar and thread on the wing nuts.
This case is a perfect fit for the DJI Phantom.

I used 1-inch elastic wide bands and stapled them to the inside of the top
to store my propellers. You can also staple bands along the sides to hold
extra parts such as your FPV LCD screen and antennas.
