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 home / landing target. Not good if currently in pit area!
If aileron / rudder wags to left , DO NOT FLY:
4 wags: Battery very low. You probably don't have enough power remaining for a safe flight.
8 wags: No radio link. Be sure transmitter is on and bound to receiver (light appears on receiver).
If aileron / rudder wags to right , FLY WITH CAUTION. Ruby may not be fully functional:
2 wags: GPS invalid. First fix may take up to 2 minutes, so you may simply need to try Preflight again. Be sure GPS is clear of wires, antenna pointing up, far from video transmitter, and at least a few inches away from switching BEC, ESC, and other sources of interference.)
3 wags: Battery somewhat low. You may just have enough power for a short flight.
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. The plane must be absolutely stationary during preflight.
7 wags: Misc. sensor or other issue. Send recorded data to support@uthere.com if problem persists.
8 wags: Radio link poor. Be sure transmitter is on and bound to receiver, and receiver and antenna is clear of wires, far from video transmitter, and at least a few inches away from switching BEC, ESC, and other sources of interference, and antenna wire is not broken.)
9 wags: Sensor orientation hasn't been set
