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.

- Page 2 At this point, your servo should be in it's neutral position. Mount your servo horn perpendicular to the tail pushrod.
- Page 3 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.
- Page 4 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...
- Page 5 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.
- Page 6 Push the rudder stick to the right...
- Page 7 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.
- Page 8 Now check that your gyro sensing is in the correct direction.
- Page 9 Leave the transmitter alone now. Hold the tail and move it to it's left, you should notice the tail blades will tend to angle towards Full LEFT. Hold the tail and move it to it's right, you should notice the tail blades will tend to angle towards Full RIGHT.
- Page 10 LogicTech gyros - Servo Limit The left and right servo limits for LogicTech gyros are INDEPENDENTLY adjustable, unlike most other gyros. This allows you to maximise performance out of your available tail travel. Doesn't have to leave an 'empty' travel which other gyros can't use. Ensure your TAIL channel's Endpoint/EPA/ATV/Travel/etc are max out for this step.
- Page 11 Now, move the rudder stick to the right, same thing, watch the tail slider. Once the tail slider touches the end, the rudder stick may not be at it's end yet. This is...
- Page 12 OK, stop moving the rudder stick and hold it at that position. Now press the MENU button once. You will notice the red LED will light up on the opposite end. This means that the gyro has already registered that position as it's 'other' operating limit.
- Page 13 To reduce the guesswork involved, LogicTech LTG-2100T incoporates a row of LEDs to indicate what is the gain that the gyro is actually 'seeing'...
- Page 21 Adjust the GAIN value in your radio and see the actual LED indication until you get the...
- Page 22 Don't forget you still have the ROTATE RATE settings to finetune the heli's tail behaviour to your liking! Experiment around and awake the potential of LTG-2100T :up *the GAIN channel endpoints can actually be adjusted so that the radio values and the...
