It uses a wifi connection between the camera and phone, get it connected in the phone’s wifi settings first, changing batteries kills the connection, do it again. sometimes the app takes a while to drop the lost connection and pick up the reestablished connection, the controls appear when you touch the screen, fade off after several seconds of no input, leaving the camera image. when I fly my camera on other quads this is the only control I have of it since the radios don’t match it, my V 262 connection works with no mods, for the power only. FLV files are HD, be sure to use a HD format when converting them or a lo res vid looks like a cartoon. I use HD MOV files so I can edit in iMovie later. Jello is common, both on the Ominus and V262, I just balanced the props and it seems to have helped. It’s hard to use the FPVcam controls while flying so I just start recording and leave it on, don’t forget to stop it before powering down or it won’t save the file. Fly smart/be safe!
