Hey guys, I'm having GoProfessional quote me on some custom case inserts that will fit the P4 with the ItElite antenna mounted on the transmitter. If there's a lot of interest for it, I will go ahead and get them ordered and put them on the website. Attached is the drawing for a backpack insert. I don't know what pricing would be, but similar to what GoProfessional cases sell for now. Also, thanks to David Bender for getting this started. He is currently getting one of these made for himself.
