A way to find out if this needs to be changed, is to clear all trim/subtrim on transmitter, and connect to GUI.
Most standard receivers will have this at 1500, however Futaba transmitters will need this set to 1520. This is an important number to set in order to avoid trimming receiver/transmitter. Denominator and gyro_lpf will together determine the control loop speed.
Denominator 2 would mean 1/2 samples will be collected.
Update cleanflight firmware on spf3 full#
Denominator of 1 means full gyro sampling rate.
This option determines the sampling ratio. Setting too high refresh rate can mean that FC cannot keep up with the gyro and higher gyro_sync_denom is needed, Note that different targets have different limits. Use gyro_lpf and gyro_sync_denom determine the gyro refresh rate. Loop will always wait for the newest gyro measurement. In this case the loop will be synced to gyro refresh rate. Enabling this feature speeds up IMU speed significantly and faster looptimes are possible.ĭefault value is Off. Setting this to 1 increases the processor speed, to move the 6th harmonic away from 432MHz.ĭefault value is 0 for disabled. Setting it to zero does not limit loop time, so it will go as fast as possible.ĭefault value is 0 for 72MHz processor speed. Default of 3500us/285Hz should work for everyone. Changing this affects PID effect with some PID controllers (see PID section for details).

If you blindly restore your backup you would not benefit from these new defaults. For instance, in December 2014 the default GPS navigation PIDs changed. When restoring from a backup it is a good idea to do a dump of the latest defaults so you know what has changed - if you do this each time a firmware release is created youwill be able to see the cli changes between firmware versions.

See the other documentation sections for details of the cli commands and settings that are available. To dump your configuration (including the current profile), use the 'dump' command. To see a list of other commands type in 'help' and press return. To exit the CLI without saving power off the flight controller or type in 'exit'. To save your settings type in 'save', saving will reboot the flight controller.
