Just bought GEPRC CinePro 2" 4K F700 with dsmx. There are no instructions on how to bind (no instructions at all). I am a noob, just fly tinyhawk 2 and freestyle, mobula6. Have absolutely no idea how to bind. Seems like some dsmx need bind plug (none provided) some enter bind on powerup, some have bind button. Any suggestions appreciated. Emailed Getfpv where I bought it for help, but probably won't get any help there. Actual receiver is not ID'd anywhere I can see.
