If you go to q>option>aircraft then insert the arrow keys as pitch forward backwards roll left and right. use hover on a key u never use. every time u gonna fly use hover press w to go up, s to go down. arrow up to go forward arrow down to go backwards. I would suggest only use a and d to turn because inexperienced flyer will lose control if he or she uses arrows left and right to roll.

I hope this guide helped you
