3) In Teleop.vi, instead of wiring anything into a WPI set servo block, wire your servo command into the ServoPos global variable.
4) Lastly, in PeriodicTasks.vi (in the fast loop), wire the ServoPos global variable into the WPI set servo block
By using the above method, PeriodicTasks is ALWAYS commanding the servo to the latched position, even when it's disabled. The output to the servo is disabled in Disabled Mode, BUT the command to latch your servo is already there as soon as your robot becomes enabled.
When you push your button to deploy your minibot, the global variable will send your servo command to PeriodicTasks which will then unlatch your minibot deploy.

Yeah, thanks for that by the way

The periodic tasks VI has been really helpful.
