need help with my gyro

[Warrior205]

Hello everybody!

I I have a problem with my gyro, it is a TG-8000, and i'm using a Futaba FF6 T6X Transmitter.

Now to the problem, i just setup my electronics today and noticed that my rudder servo was buzzing, i presume if the model was flying it would be tail wagging because the servo was very slightly goin back and forth, and i think the gyro gain may be set to high, but how do you adjust the gain on the gyro? On the gyro itself their is no gain settings just a reversing switch, and their is no gyro gain setting on the transmitter. I am very confused with this, and frustrated somwhat. Maybe i got a budget transmitter and do not have this luxury.

Please help me

P. S. I will going to work shortly, so i will not be able to reply until work has finished[/quote]

I'm not too clever on the FF6, does it have a spare channel, usually the gear channel 5.

Use your ATV's to give a % for HH and Normal depending on switch position.

If your servo is a digital then buzzing is normal.....

You'll know when the gain is too high as it will start to really wag when hovering, just bring down the gain slowly till the wag goes....

Hi Nev,

The FF6 transmitter you have, should have the following in terms of channel layout;

1 - Aileron
2 - Elevator
3 - Throttle
4 - Rudder
5 - Gyro Gain
6 - Pitch

The gain will be switched from the switch on the top left hand side of the unit, the way to set the gain is to use the ATV's for channel 5, when you go into the ATV settings flick the switch and you should see it swap between the high and low ATV, if you have the gyro channel set to normal as opposed to being reversed, the low ATV will set the gain for normal mode and the high ATV will set the gain for the heading hold mode.

I believe the TG-8000 to be a single rate non heading hold gyro, in which case there will only be one gain adjustment for it, that being the low ATV.

Set the gain to be around the 70% mark initially, then test fly it adjusting as necessary until you are happy with it. To do this slowly increase the gain until the tail starts wagging like some sort of excited dog and then back it off slightly, just enough to stop it wagging.

I hope this helps.

Cheers,

Pete.

Sorry for the long delay in replying to this post.

I did what you said raptorite, but i cant see any visual differences with the servo when using the ch5 switch on the transmitter, i put my gyro into channel 5 on the reciever.

I am not at the flying stages yet, and am wondering if their are any visual differences in flippin the channel 5 switch, and adjusting the ATV for ch5? becuse i cant see any and i would like to set up the heli before i try to fly.

And that switch you said for switching the gain is on the upper right of the transmitter and not the left, their is no channel 5 switch on the left.

Oh and by the way, where do i get this coloured film that i use to balance the blades?

Thanx in advance

Does your Tx look like this.....

I used to fly with the FF6 and the gyro gain switch is as per Stuarts diagram above the cyclic stick (right).

I still have a Nexus setup with a CSM400 gyro using ch5 for HH/non HH switching. The gain is set with the ATV on that channel.
