Example - landing flaps:

Both landing flaps are to be controlled using one channel; this is channel 5 at 
the transmitter. Assign 

DIRECT 5

 to any two outputs, e.g. 

Q

 and 

R

. Now plug in 

one landing flap, and set it up accurately at the transmitter. The other landing 
flap is connected and adjusted later, i.e. during the servo matching procedure.

The final point in the Basic Setup Assistant is to define the direction of gyro 
effect, and the integral

 iGyro

 activates itself to allow this. By physically moving 

the model you can check whether the gyro’s effect is in the correct direction; 
reverse it if necessary.

Note:

 if, for example, one elevator channel is used for both sides, the direction 

of effect must be rechecked if you subsequently reverse that output in the servo 
matching menu. The direction of effect can then be corrected manually using 
the iGyro menu.

5. Servo matching

At this juncture you can reverse the landing flaps and elevators, and adjust the 
servos’ centre and end-points if necessary.
If your model is fitted with more than one servo per control surface, this is the 
time to fine-tune the servos to match each other, and connect the control 
surface linkages.

6. Door Sequencer Assistant

Start the Assistant, carry out each step exactly as described on-screen, and 
then connect the servos and / or valves one by one. As of Version 07 the 
system incorporates a second front wheel door, which makes it possible to 
complete the set-up procedure for the whole retract sequence in about ten 
minutes.
If you also need to adjust the process times, we suggest that you visit our 
Forum, where you will find a list of all tasks in the FAQ section. It is a very 
simple matter to adjust the pause and running times for the doors manually.

7. Setting up the iGyro in flight

The final step is to adjust the gyro’s settings in flight. This is accomplished by 
selecting the 

TEST FLY ASSISTANT

, and adjusting all three axes while the 

model is in the air. We recommend that you carry out several ‘dry runs’ on the 
ground in order to familiarise yourself with the sequence of operations.

The 

Royal SRS

 is now fully set up, and we wish you great fun and success with 

the system!
