You can use my Walkera CP Helicopters - 3 Difficulty Modes model. You will have to change Protocol=DEVO to Protocol=WK2801. RX2616V works with WK2801 and all 260X transmitters.
Also you might need to set the Pitch to Reverse. Everything else should be set to Normal. Double check everything before you try to fly the helicopter.
