I have installed an i2c Maxbotic sonar on my quadcopter which is working fine in Alt_Hold mode. When I run a terrain mission and set the altitude to 1 meter in the waypoint, it actually flies at about 1.8 meters. I have set params to:

Does anyone know how I can get it to fly at 1 meter in auto mode terrain follow?
