iGyro 3e

Gyros are slowly gaining ground from the tabu they where just a few years ago, now being used on anything from small Horizon BNF models up to the largest jets.

Lets start by clearing up some myths and explaining what a actually gyro does:

-It detects when the model is being changed direction when it was not instructed to do so by the pilot (radio).

What this means, is that when we, the pilot, instruct a change of attitude (be it on ailerons, elevator or rudder) and the gyro then detects the models change of position or atitude, it understands that this is an intentional change, and therefore does not affect our input in any way.

When the gyro detects a change of position, but there wasnt a stick input by the pilot, it detects that the movement was therefore undesireable, and due to a gust of wind or similar external influence, and will move the servos in such as way as to prevent said change, all this blisteringly quick resulting in it visually looking like the model didnt ever move, despite the winds best attempts.

 

-Based on the above, when flying without any wind, the gyro will not have any affect on the model as there should be no unintended position changes as there are no external influences.  Therefore flying in calm conditions should be the same with or without the gyro, we should only see a difference when windy.
*There is an exception to the above, being when the gyro corrects inherant faults with the model, such as  ugly wing wobbles or fishtailing, which should always be corrected by the gyro, whether it is windy or not.

-A gyro is therefore a wonderfull electronic device which allows you to enjoy flying in calm conditions, even when the conditions are in fact not calm at all.  What it wont do is fly the plane for you (its not an autopilot) and therefore wont mean that you can suddenly perform manouvers that you didnt know how to before installing the gyro.

The iGyro 3e is a very simple but complete gyro. It incorporates within one single box, 3 gyros, one for each of the three axis that we use (ailerons, elevator and rudder)

1-Instalation is as simple as putting the iGyro in between the receiver and servo conections.

2-Add one more wire going from the gyro to the receiver, this will control turning the gyro on or off, and the amount of gain that will be used by the gyro. Use a trim or slider for this channel that will allow you to adjust the amount of gain required.

3-From your PC or with the BlueCom (Powerbox bluetooth adapter to conenct using your phone) select how your gyro has been installed (in what position).  From here you can also select if your model is a delta, and make some fine tuning to your gain settings.

4-Check that the iGyro is correcting all surfaces in the right direction.  Move the slider on your radio to the maximum position so the gyro is on full gain (100%) One by one, move the model on each of its axis, the surface should move in the same direction that you have moved it.  If not, we need to reverse the gyro correction of that channel.

 

-To reverse one axis, hold down for 5 seconds the button on the gyro, until all led go out.

-Upon releasing, just one led will light back up.

-If that is the cannel that we wish to reverse, press the button once more and the led will change colour, and the gyro channel will have been reversed

-If we wanted to adjust a different channel, simply press and hold down the button, the lit up led will slowly progress through all the channels.  Once it arrives at the one you want to reverse, release the button, and repeat the reversing process.

 

5-For the test flight, fly and adjust the model without the gyro, and then once flying well, slowly increase the gain on the gyro until the model is no longer affected by the wind.

*If the model starts to “vibrate” (fishtailing) on any of the axis, it is due to too much gain. The fastest way to stop the model from oscilating is to reduce its speed by throttling back and pulling up.  Once the model stops oscilating, simply reduce the gain and try again.
