Hi folks, Steve Kaluf here for Futaba video update. In this segment we're going to be
talking about the GY520 gyro. This little 6.9 gram wonder revolutionized the gyro world
about a year ago when it was released. The main topic that we're going to be discussing
is to see how you two and how to utilize this usb interface and the GY Link software on
the computer to set each of the parameters that the GY520 has available to it. We're
going to take a look at the GY Link software. We've plugged our gyro into the GY Link through
the usb port which is the CIU2. First two things we're going to see here these are not
things that we need to worry about the ID set automatically that by the gyro. Each gyro
has a unique ID assigned to it. Coming down here to flight mode we have two different
flight modes. We have F3C mode and 3D mode. These determine the or set the overall feel
of the gyro. The F3C mode is a little more general feeling, the 3D mode is a very aggressive
initial setup. You'll want to only go into here if you are extremely aggressive in your
3D line. Most guys in the U.S. are using this gyro in the F3C mode. Servo mode is where
we just quickly determine what type of servo we're using. We have digital 1520 ms, we have
digital 1760 ms and of course we have the analog mode because you can use this gyro
with analog servos. The gyro reversed that's our normal reversing this determines that
the actual direction of the gyro. Now near-surface is unique to this gyro. If you're mounting
the gyro with it facing up you want it set on the upper side and if you are mouting it
with it facing down you'll set it on the bottom side. Then we come up to respond setting.
We have a fast, a standard and the slow. Again most guys are going to be runing this in the
standard setting. If you go to fast, this is going to be extremely aggressive tail stops.
If you go into the fast mode, use this very carefully and proceed carefully to determine
that you're not going to damage your machine on a very fast tail stop. When we get into
control response this actually sets the delay operations and you can set the right and left
separately. When you increase the value, the delay is going to increase. When you decreases
it, delay will decrease. So if you get a lot of rebound on the tail stop, you'll want to
increase the value just a little bit too try to dial that rebound out. ABCS response mode
is our heading hold settings. We have the ability to set both right and left in and
out. This adjust the tail operation response speed. When the set value is increased, the
response speed decreases. In this the delay setting when the rudder stick is moved left
and right from the neutral position of course out is the delay setting and the rudder stick
is returned to neutral position from left and right. The left and right in / out delay
can be set separately so the rudder operation and the rebound feeling can be dialed into
exactly what you want it to be. Here we go down to pirouette consistency and this selects
the overall feeling for your pirouettes. You'll have to play with this a little bit to get
it just exactly where you want it to be. EXP is are expo settings it's the same type of
thing that you would set from your transmitter. We have both to two modes here, two different
flight conditions so we have the normal mode and the ABCS or heading hold mode. Remember
with Futaba systems if you go into the negative numbers that is going to be your softer feeling
around neutral. So what typically if we're going to set an expo we're going to be in
the softer feel. ABCS settings up here are our yaw rates an our gain and our range. What
are yaw rates are going to do for us is set the rotational speed of the gyro or of the
tail itself. We increase this then we're going to get a lot faster rotational speed. With
the initial setting of 100 here in the F3C mode we're going to see about 450 degrees
per second. If we're into 3D mode, we're going to be at 720. The GY520 is capable of 800
degrees per second so again you're going to want to set this very carefully. Range is
going to affect the amount of servo throws. At 300 we're going to be seeing about 40 degrees
of servo throw. When we get into D gain, this is the differential gained and dampening.
So if we want to increase the gain value for differential we'll simply have run that number
up and of course the dampening we can run that up or down depending on how the tail
feels. Now when we get down to the limits here this is kind of a unique an easy very
easy way to set your limits up on the tail. We're going to go to a split screen here so
you can see both the tail of the helicopter and what I'm doing on the on the computer.
So to begin this setting we simply click 'enter' and then we're going to set our first limit
position and what we're going to want to do is to move this over and to get max throw
but not binding, you can see I went to the end and now I backed off a little bit. Now
I'll click 'set' and I'll go to the other direction. Again I'm going to go all the way
over to the end and I'm gonna back off just a little bit until we aren't hitting anything
and I'll click 'set' again. So now we've we've set everything up and we're ready to send
the information to the gyro. All that we have to do now is click 'write'. It's loading the
gyro. You can see that we've succeeded here. We click that 'OK' and we're done. Now what
i like to do is to be to hit read now, read that information back from the gyro make sure
that all my settings have changed and then of course you can go up to file and save the
settings. I hope you enjoyed this quick look at the GY520 gyro utilizing CIU2 usb interface
to allow it to use GY Link software and set all the various parameters of the GY520. So
for Futaba video update, I'm Stevek Kaluf. We'll see you next time.
