Here are all the components needed for the Mavic Pro Parachute system.

We start by installing the Mayday Fail Safe Controller into the mount. TIP - Before you start you can use some masking tape to secure the hinge pins to the mount so they do not fall out.

Holding as shown ease the Mayday past the vertical catches. Note the orientation of the buttons and connectors.

Then push back under the horizontal piece.

Then snap into place.

Cut the Velcro so it just fits on the battery and battery compartment.

Put one piece onto the battery compartment base.

Put the other piece on the back of the battery.

This shows the Velcro installed on the battery. Note the orientation relative to the battery wires.

Then press the battery onto the mount. Note there is a gap in the fence around the battery where the leads can exit. IMPORTANT - Be sure to charge the battery before flight!

This shows both the Mayday and Battery installed and in the correct orientation.

Next route the battery power connector with the JST connector around the bottom of the mount and under the clips.

Pull the power wire back until the connector is as shown.

Then plug in the JST (2 pin) to JR Servo (3 pin) adapter onto the battery connector.

Route the extender around the mount and under the clips.

Make a single loop as shown in the routing. This positions the JR 3 pin connector at the right place to connect to the switch.

Then complete routing around the mount top and under the clips.

Take the switch out and notice it has a female and male connector. If your switch has three connectors the extra female end needs to be cut off, it's not needed.

Place the switch into the mount tabs. The switch is oriented so the male connector goes to the mount top so it can plug into the extender. The female end faces down so it can wrap around under the Mayday and plug into it.

Use a small Phillips screw driver to secure the switch.

The switch is not secured to the mount.

Plug in the switch male end onto the JR female connector. Make sure the wire colors match up with black to black, red to red.

Stow the extra wire under the wire clips.

Route the female JR end around the side and bottom and stow under the clips.

Plug into the Mayday power connector (back connector that is wider). The power connector is marked with a "P" next to it.

Test the connection by turning on the power. Push the switch down to turn on.

Next we are going to mount the Harrier 40mm canister to the mounting cradle. For this you need the 8" long Velcro strip.

Start by routing the Velcro strip through the mounting slots.

Pull the end so the strip is centered.

This shows the strip installed and centered.

Next orient the Harrier into the mount. Notice the cradle has a catch that sticks up and will go into the slot on the launcher base. Generally the label will be oriented down, which is the correct orientation.

This shows the launcher base aligned with the cradle correctly.

Now Velcro the launcher securely to the mount cradle.

Wrapping the Velcro around the launcher.

The launcher is all set!

Route the Servo wires under mount to the electronics tray.

Again secure under the clips.

Plug into the Mayday servo output (marked with a "S"). Again secure the wire under the flips. This view shows the completed mount bottom. The extra battery connector is used for charging.

Now we mount on the copter.

Remove the hinge pin so the closure can be opened.

Flip the closure door up.

Drop the Mavic down into the mounting band. Note there are alignment tabs on the bottom that engage into the Mavic bottom center between the sensors. Adjust the mount so the bottom of the mount is flush and centered on the Mavic bottom. When properly aligned the closure door will just reach around the Mavic body securely.

Note the battery release buttons each fit into the opening on the body. There is also a button clearance cut under the Harrier mounting cradle. These help keep the mount in place on the body and from sliding around.

This view shows the proper alignment of the mounting body which is critical to the fit.

With everything aligned the hinge pin can be inserted. Pull the hinges together into alignment and insert the pin. The mount will fit snug around the body with just a little bit of stretch. Once set, the mount will stay securely in place.

The hinge pin ends are folded down and tucked next to the stops that keep them from backing out.

Now we will rig the harness to the copter. NOTE: Some of these slides may be out of order due to a bug in the Gallery. So review the remaining slides to see how to rig the copter.

Work the harness into the harness stow on each side and pull on the end so the line is taught.

Take one end of the short 8" harnesses and hook through the other end loop and around the front rotor booms.

Pull tight. Next we will work the harness into the harness stows on each side.

Open the quick link and connect over the harness loop ends.

Then snap the quick link onto the mount.

Connect the shock cord loop out of the canister onto the quick link and close the link.

The harnesses are all set and ready for the quick link.
