 In this mode THROTTLE stick controls climb rate (vertical velocity). When pilot moves stick up - quad goes up, pilot moves stick down - quad descends, you keep stick at neutral position - quad hovers.
 
 ### CLI parameters affecting ALTHOLD mode:
-* *nav_use_midrc_for_althold* - when set to "0", firmware will remember where your throttle stick was when ALTHOLD was activated - this will be considered neutral position. When set to "1" - 50% throttle will be considered neutral position.
-* *nav_throttle_tilt_comp* - when set to "1" firmware will automatically increase throttle when copter is tilted and in ALTHOLD mode.
