Help with reverse throttle on Fly Sky GT3B

I have reversed throttle and cannot figure out why....help.

It should have a setting to reverse the servo

I have not had any experience with the Fly Sky GT3B so im going out on a limb here! If it is like the Traxxas TQi link controllers it should have something that resets it to factory defaults. The traxxas controller goes like this... transmitter off, hold menu and set, turn transmitter on, let go of menu and set, then hit menu, then it should blink red, then hit set then it will blink green. Thats what it does on the traxxas controllers but idk about fly skys

click the wheel, turn it to highlight REV and click the wheel again, select the channel to reverse press end button, turn the wheel to select rev(read) or nor(mal) and click the wheel to set. You should be good to go.
