Futaba gy520 gyro setup

To further enhance mounting flexibility and wiring compactness, the GY has been equipped with a unique wiring connector that is at the end of a 5-in. This three-port connector block allows the use of servo leads of varying lengths customized to the needs of each particular installation. Since the connector block is located separately from the gyro, the tail-rotor servo can be placed further away from the gyro without the use of additional extension cables.

Six basic programming options can be input through the programming button on the right side of the gyro case. A tri-color light-emitting-diode LED , which can glow red, blue, or violet, is located on the top left corner of the gyro case. This LED displays the programming status by flashing one of three colors a number of times. To enter program mode, the button is depressed for a few seconds until the LED flashes violet.

Once program mode has been entered, the LED will flash a certain number of times, pause for a bit, and then flash again. The number of flashes indicates which option is selected while the color of the flash displays the current setting stored. To advance from one option to the next, the programming button is pushed until the LED flashes violet briefly. Once the desired option has been selected, its value can be altered by pressing the button a few times in quick succession.

The endpoint adjustment option differs from the other options in that it also requires the transmitter to input the high and low side values for the tail-rotor servo. In addition to the basic options, settings like exponential, AVCS response, gain, and range can be altered with the use of the GY-link software to suit the flying styles of more demanding pilots.

The average pilot will probably find the most useful feature of the CUI-2 option to be the ability to edit and store individual setups for different helis. Installation In order to judge the performance of the GY equitably, I decided to test it on two of my helis that have been flown with a Futaba GY and Futaba tail-rotor servos.

I also have had a GY on my Trex since I first built it a few years ago. It has worked very well with the matching S servo in that role. The GY was attached to the gyro shelf of the Axe with a single layer of the included sensor tape. The excess wiring was bundled up and taped to one of the tail-boom braces. The two male-to-male servo extensions supplied with the gyro are over a foot long and together weigh more than the gyro itself. If you are using this gyro on a very small helicopter where even a few extra grams may be noticeable, use one of the smaller sets of connection cords available from Futaba.

Since the GY with the stock extensions weighs less than the GY it replaced, I elected to just use them. On the Trex , two pieces of sensor tape, with the included damper plate sandwiched in between, were used to mount the gyro. On larger electric and glow helicopters, additional vibration absorption material is recommended to prevent the extremely sensitive senor in the GY from being overwhelmed.

Most other receivers have it labeled channel 5. Click on the photo on the left to see the other two connections. Standard Rate mode Flip the Gear switch up position 0 and confirm that the light on the gyro is solid red. Please provide as much info as you can. Now that you have found a position for the servo arm you need to mount the ball on it. If all of this checks good then continue to step The gyro could be set for the wrong type servo.

For the first second the light will blink slow. At the left, look at the top picture. You should make the decision based on what your flying style is. The light on the gyro will do a 4-Blink. If not, hold the button down to enter setup mode. Once you have the servo type correctly set then hold the button on the gyro for 2 seconds to move to the next function. Use an exacto knife to shave this off. There are three things that need to be connected. And the tail control rod link needs to be disconnected from the tail servo arm.

If not gy go back to step 1 and start again. That is very helpful. It also depends on how the link connects to the servo. Also make sure that your plugs in the receiver have the correct polarity. He is running a DX7. This tells the radio that you want to control the Gear channel of the receiver by using the switch on the radio that is labeled Gear. Next check that the gyro can sense the helicopter is moving. Verify the gyro is in Heading Hold mode, light on the gyro is Red.

A high framerate setting manuao a low framerate servo will damage the servo in a minute. The light on the gyro will turn solid Blue. Now flip the switch down and confirm the gyro is now solid blue. Options Quote message in reply?

This would be very simple for Futaba to have ,anual and would save some confusion. One direction will set the gain value for heading hold and the other will be for standard rate.
