Cant find my manual but if you are stuck reversing the channels try this;

(throttle)
hold down the trigger towards your palm as if you were going to accelerate . and hold the throttle trim down til it runs out of numbers after 2 seconds it will say REV
(steering)
hold the steering left on the controller , but push the button towards the right on the steering trim till the numbers run out n it will say REV
