Door Sequencer; Airspeed Factor; Expert Menu; Setup Assistant - PowerBox Systems Mercury SRS Instruction Manual

- AIRSPEED FACTOR: after the gyro test-flight the airspeed factor
defaults to a value of 3. If you subsequently discover that the model
starts to oscillate at high speed, but behaves perfectly at low speed, then
you need to increase the airspeed factor.
The higher the airspeed factor, the lower the gyro gain as the model's
airspeed increases.

9.4. Door sequencer

The door sequencer in the Mercury SRS provides completely unrestricted
facilities for implementing control systems for retractable undercarriages
and canopies. All sequences are controlled by means of "TASKS".

- SETUP ASSISTANT:

We recommend that you start the adjustment process using the SETUP
ASSISTANT. This step-by-step guide to setting up the system presents
the tasks in the appropriate order, automatically locates the channel for
the retract switch, and assigns the door sequencer outputs in OUTPUT
MAPPING. The SETUP ASSISTANT is described under Point 6.

- EXPERT MENU:

If you work through the Assistant procedure and then find that some
fine-tuning is desirable - perhaps in the timing of the sequence - you can
make these changes in the EXPERT MENU:
The TASK is the key to all adjustments. A Task can be defined as the
movement of one servo from the start position to the stop position, with
defined start and stop times. Twelve tasks are available for the retraction
process, and a further twelve tasks for the extension process. This means
that it is possible to program 24 different movement sequences.
