(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.
