Logitech LTG-2100T Setup Manual

Logictech LTG-2100T Gyro setup guide

(most sections apply to other gyros as well)

Recommended servos for LTG-2100T
Mini helis - Futaba S3154 digital micro servo
Standard size helis - LTG-6100G Digital high speed servo(0.05s)

Install the gyro on a suitable flat platform on the helicopter's frame as indicated in the
instruction sheet.

Take note to use a suitable mounting tape, the tape that comes with the gyro works best
on most surfaces. You can experiment with different tapes if deem necessary. When
securing down the gyro leads, do leave a bit of slack in the leads. The leads MUST NOT
be strained as this will transmit any frame vibrations to the gyro, reducing it's
effectiveness in yaw sensing accuracy.

All connections to be hooked up as indicated in the instruction sheet as well. Most flyers
don't have misunderstanding in this area.

As different radio manufacturers uses different channels for the rudder and gain, I will
term them as follows:

Rudder/tail - TAIL channel
Gain/Gyro - GAIN Channel

Please go thru your radio's instruction manuals to ensure it's clear before we proceed.

***Disregard the broken tail part, I just crashed it....***

Switch on the radio and neutral the TAIL channel.

Adjust the GAIN value on your radio's appropriate channel until the green LED on the
gyro is OFF and the RED LED is at the 1st or 2nd position from the left.
Make sure the Revo-mix is OFF or INH.

We must go thru the mechanical setup first.

General heli's tail rotation is upwards, sweeping into the main rotor's downwash.

At this point, your servo should be in it's neutral position.
Mount your servo horn perpendicular to the tail pushrod.

Before we proceed further, let's go thru the servo selection feature for LTG-2100T.
Get into gyro setup by pressing the MENU button and holding on to it until the LED goes
to the first setting. Let go. You will see the green LED at SERVO SPEED and a red LED
above.

The rudder stick is used to shift the red LED left and right to desired positions for setup.
Experiment with it and you will understand immediately.

To change move the red LED to the suitable position, hold the rudder stick one direction
or the other and press the MENU button once. You will notice the red LED shift a
position.(if not, hold the other direction and press the button). Choose the suitable servo
type selection

Once the suitable servo type is selected, neutral your rudder stick and press the MENU
button. You will notice the green LED will shift down to ROTATE RATE. Same thing

goes, but set it to the slowest for inital tests first.
You can use it to fine tune to desired likings after everything is done.

Now exit gyro setup by simply neutral rudder stick and don't touch the gyro. It will exit
in a couple of seconds. You will notice it will go back to the gain indication screen as
when you just initialise it.

Now let's take a look at the tail rotor's action.

With everything hooked up, push the rudder stick to the Left

Push the rudder stick to the right

This pictures are taken on the mini titan, please note that the tail blade is the thing to look
at, the pitch slider's position may be different for other helis.
If the tail blades actions you see on your heli is opposite, REVERSE the TAIL channel.

In neutral state, the tail blades will have a bit of an angle, eg 10 degrees

In order to get the neutral state tail blades angle more or less in the ballpark, adjust by
sliding the tail boom servo mount forward or aft. Alternatively, you can also adjust the
pushrod ball links.(for frame mounted tail servo, this is the only option)
