RTL Speed

I’m flying a Cheerson CX-20. Is there a parameter that controls the speed at which the quad flies when activating the RTL mode? I’m new to flying the CX-20 and have only tried the RTL a few times. When I did it seemed to take a rather long time to get back.

I have changed the ANGLE_MAX parameter to 3500,

THanks,
Bruce

WPNAV_SPEED should be the one.
