Re: Go professional backpack at a crazy price on Facebook...
Here are photos of my backpack case that cost $80 plus shipping.
[*]FIELDLINE TACTICAL ALPHA OPS DIGITAL INTERNAL FRAME HYDRATION BACK PACK - Walmart for $44.99
[*]Fastcap 1-1/8 Thick Kaizen Foam, 2' x 4' $13.69
[*]2-1/4 Thick Kaizen Foam, 2 ft x 4 ft Sheet $20.99
I used a knife and hot screw driver for the cutouts. The screw driver was heated up with a blow torch (you could use an iron or stove), and was used to smooth the edges and create holes for the antennas. The case also holds my FPV monitor and chargers. Remaining external pockets can be used for anything. It also came with a hydration reservoir. I slip the props along the side of the foam. I took out the stays (stiffener) since they are not needed and I used the excess foam created a lumbar pad.
