I have a CGO 2+ camera and steady grip that I use for ground work only. I do not have a Typhoon 500 with which to upgrade the camera firmware to the latest version. If someone near (like even as far away as St. Louis, Paducah, or Cape Girardeau) has a Typhoon 500 and would be willing to flash the camera for me, I would be glad to drive to you for the assistance. Thanks...
