The D4 Quad consists of a CS4, inside which you can optionally place either the Drone Foam for the Mavic Pro 2, or the Drone Foam or the Drone Foam for the Mavic Air 2.
Also, of course, you get the Pocket Cap Front to organize all the additional small stuff that goes with being a UAV Pilot. And finally the Pack Cap Rear is included, which allows you to choose whether you want the bag to be a backpack or not.  You'll get two Side Pocket Charlies, one for each side. These work great for holding spare props or even more batteries, etc.

The D4 Quad also includes a Main Handle and a Shoulder Strap. (Most of the time, it's nice to keep the backpack straps stowed away and just use the Handle and the Shoulder Strap.)

Note that when you receive the CS4, it will by default include a "divider shelf". This part won't necessarily be useful with the drone foam installed and you can set this part aside. The "divider shelf" is used in the Flight Bag world for separating two headsets inside the CS4.


Interior of CS4: 13.5" tall, 10.0" wide, 4.0 inches deep. (35cm x 25cm x 10cm)
Exterior of entire bag: 14.0" tall, 13" wide, 8" deep. (36cm x 33cm x 20cm)
Keep in mind that the bag material is flexible, so the size of the interior storage may be able to "stretch" out just a bit in one direction or another. Also keep in mind that over-stuffing your bag can cause seam or material failure, and this is not covered by warranty.

Empty Weight

4.4 lbs. (2 kg) - Bag only
0.4 lbs. (0.18 kg) - Drone Foam

Total Number Of Available Flex System Side Pockets

Two. One side pocket mounting station on each side of the CS4.

  • Pocket Cap Front
