19  Setup Software & Advanced Features Guide 

The main window of the setup software is broken down into three areas: 

 

The menu bar provides access to the program’s features and functions 

 

The  Live  Data

  region  is  updated  in  real  time  whenever  the  gyro  is 

connected to your computer with a USB cable 

 

The 

Offline Setup Values

 tabs display the values for your gyro’s current 

helicopter setup file 

 

Menu Bar

 

Items in the 

File

 menu include: 

Load  Setup:

  Click  this  menu  item  to  load  a  setup  from  your  computer’s  hard 

drive.  The 

Offline  Setup  Values

  tabs  will  be  updated  with  newly  loaded  setup. 

Any  setup  sent  to  the  gyro  will  be  labeled  with  the  first  16  letters  of  the 
configuration file’s Windows filename. 

Save Setup:

 Use this menu option to save a setup to your computer’s hard disk. 

This feature is useful if you want to experiment with different settings or backup 
your current settings to disk. 

Replay Flight Log:

 Select this item from the File menu to replay your flight logs 

in the 3D viewer. See Section 16 of this manual for detailed description of how to 
use the 3D viewer. 

Upgrade  From  SK360:

  Use  this  menu  item  to  import  a  stored  SK360 

configuration  file  into  the  SK720  configuration  program.  The  imported  SK360 
configuration can then be tweaked and loaded onto your new SK720. 

Items on the 

Utility

 menu include: 

Bind Sat RX on Power Cycle:

 use this option to bind any satellite receivers that 

are  connected  to  your  SK720  to  your  transmitter.  Connect  the  SK720  to  your 
computer  using  a  USB  cable  and  then  select  this  option.  All  connected  satellite 
receivers  will  go  into  bind  mode  the  next  time  that  the  SK720  is  power  cycled 
(i.e. turned off and then on again). 

Reset Log Counter:

 When flight logging is enabled (see the Control Tab section 

below),  selecting  this  option  causes  the  log  index  number  to  be  reset  to  zero. 
Thereafter, log file names will be “LOG0.BIN”, “LOG1.BIN”, etc. 

Reset  Gyro:

  Selecting  this  item  on  the  Utility  menu  causes  the  gyro  to  reset 

immediately.  The  unit  will  disconnect  and  then  reconnect  to  Windows  in  the 
process. Ensure that all open files on the SK720 flash drive are saved and closed

before selecting this option. This option is useful when binding satellite receivers 
because  it  allows  the  unit  to  be  reset  without  having  to  disconnect  it  from  your 
computer. 

Format MicroSD Card:

 This option will permanently erase the contents of your 

SK720 mass storage device. Be sure to back up any important files (such as the 
SK720 setup software directory) before selecting this option. Note that the format 
is done by the SK720 itself. Use this option periodically to improve the speed of 
writes to the SK720’s flash drive. The gyro will disconnect and then reconnect to 
Windows in the process and it may take 30 seconds or more to complete.

 

Update  SK-720  Firmware

  –  SK720  program  (firmware)  updates  will  be 

provided from time to time by Skookum Robotics. Select this option and follow 
the  on  screen  instructions  to  update  your  SK720  with  the  latest  software 
improvements.  

Update  SK-LCD  Firmware

  –  Choose  this  option  to  load  the  latest  software 

revision  (firmware)  onto  your  SK-LCD  accessory.  The  SK-LCD  must  be 
connected to your SK720 before starting the update. 

Live Data

 

 

Figure 19.1 – SK720 Setup Software 

Live Data

 Region 

This area displays live telemetry from the gyro, including your radio 

Inputs from 

Receiver

  and 

Gyro  Motion

.  Remember  that  while  in  setup  mode,  all  elevator, 

aileron  and  rudder  stick  motions  are  sent  directly  to  the  helicopter’s  servos  to 
allow for easy mechanical setup. See Figure 19.1.
