Launch the model and y at half-throttle parallel with the landing strip. Increase gyro

gain until the aircraft just starts to oscillate around one axis. At this point reduce gain

slightly until the model shows no sign of oscillating in any speed range.

Note: if you are using the Mercury SRS without GPS II, it is vital to ensure that the

gain you set does not allow the model to oscillate even at full-throttle.

Please take your time to complete this step properly! If the rst level pass is too short

to enable you to turn up the gain as far as you would like, simply carry out another

pass. If you are not condent of doing this, ask a friend to adjust the gyro gain setting

for you.

If there is no wind at all when you carry out the set-up ights, it can be helpful to give

the gyro a little “work” to do: briey move the sticks away from centre to check that the

model maintains its heading accurately, without any tendency to over-correct.

The ideal test: set the model in the knife-edge attitude and adjust the rudder on its own

to maintain a steady height; leave the aileron and elevator sticks alone. The model

should now y exactly straight, without any hint of oscillation.

This nal test is by no means essential, but it does provide a very clear demonstration

of how effectively the iGyro does its job!

When you are sure that gyro gain is set correctly, move the ight mode switch to select

FM1. This causes the iGyro to adopt the previously selected gain setting, and also

immediately adjusts your pre-dened iGyro ight modes. Once you have done this, you

are free to activate the ight mode you wish to use.

Example: gain setting established during the set-up ight: 37%. These values are ad-

opted for ight mode 2, while ight mode 1 and ight mode 3 are automatically adjus-

ted by the Assistant based on your earlier inputs.
