Rubytm Field Reference Card: Preflight

Hold aileron / elevator stick in a corner as you flip mode switch 3 times, starting and ending in aided or autonomous position.

Ruby will immediately wag all control surfaces to indicate beginning of preflight.

After 5 seconds, Ruby will wag controls to indicate status::

If elevator wags, OK TO FLY:

3 wags: plane is currently more than 30 feet from home / landing target.

5 wags: plane is less than 30 feet from target. (Not good if currently in pit area!)

If aileron / rudder wags to left , DO NOT FLY:

4 wags: Battery very low

If aileron / rudder wags to right , FLY WITH CAUTION, Ruby may not be functional:

2 wags: GPS invalid (First fix may take up to 2 minutes. Be sure GPS is clear of wires and away from switching power supply.)

3 wags: Battery somewhat low

5 wags: Magnetometer distorted (be sure that the plane is away from car, tools, watch, etc..)

6 wags: Preflight never completed because plane never stopped moving

7 wags: Misc. sensor or other issue (send recorded data to support@uthere.com if problem persists)

8 wags: Radio link poor

9 wags: Sensor orientation hasn't been set
