STEP 1: SELECTION OF TYPE OF RECEIVERS
The internal software of the LTG 2100 is able to recognize the type of receiver which is used. It allows him to
match on the theorical neutral signal of the receiver and thus avoid the phenomenon of "drifting", which can happen
with other brands of gyroscopes when connecting receivers of a different brand. For a beginner, it means that the
gyroscope is compatible with all the market receivers without having to make specific manipulation, and for the
insiders, we say simply that it will not be necessary in most cases need to modify the " sub-trim " to allow the
gyroscope to initialize correctly and without drifting from neutral.
If despite a perfect tail linkage adjustement in Rate mode (please see manual below for exmplanations) and a proper
setup, your helicopter is still drifting, please contact your Logictech Service Center. It is possible, in some cases,
after a hard crash, that the Gyro PCB has moved in the Gyro case and needs to be taped back in the gyro case. This
allows the PCB to move in the case of a hard impact in order not to be damaged.
The gyroscope must NOT be connected to the tail servo until Stage 3. THIS IS VERY IMPORTANT !
Turn on your transmitter and make sure that there is no mixing on the path of anti-and gain. Make sure all the trims
and sub-trims are neutral, and that the exponential functions are not enabled. Verify that the "Dual Rate" is well at
100%, and that the boundaries of the track servo anti only to be maximum (See the manual of yourtrasnmitter, or
contact us at www.e-copter.com for more information).
-
Connect your gyroscope on the receiver if you have a standard FM / PPM / PCM system. For other systems,
please see the note below (receiver must be off).
There are 3 wires out from the gyroscope
:
- One has a male socket (it is the only one). This cable will be connected to tail servo at step 3.
- The second has a female plug with 3 wires. This cable will plugs LATER into the receiver on the rudder output
( please respect polarities and signal).
-
The last cable has a single wire and has a blue plug This will be connected right now to the Gyro Gain receiver
output ( most of time, channel 5 or AUX 2 ).
Note about the receiver recognition
: due to some specific power up cycles on new transmitters ( especially Spektrum
transmitters) you will have to turn on your transmitter, then your receiver, and only after initialisation of the receiver,
you will plug the gyro rudder plug. UNPLUG YOUR ESC PLUG AND MOTOR PLUGS !!!
- Put the rudder stick full left (after Transmitter and Receiver are on and working), and now, while keeping the
transmitter rudder stick left, plug the rudder plug of the gyro on the receiver. Do not move the rudder stick of the
transmitter now, you will see the first 3 red leds move from one to the other for a few seconds, wait the second cycle
and let the rudder stick go back to neutral.
Cycle power your receiver and the receiver is now recognized. If the procedure does not work, repeat the operation
with rudder stick on the right, and make sure that no mixing is activated and all values are as described at the
beginning of step 1. In any case, once the procedure done, you can simply go in the Gyro menu and check that
keeping the rudder stick left or right with pressing the menu button at same time changes the values of the functions
menu you are in at the moment.
(
Do not connect a servo until you have solved the servo type in " servo speed. "
)
Once the gyroscope has recognized the type of receiver, shut down the receiver then back so that the changes could
be taken into account.
A special note for Spektrum Originals 2.4 Ghz equipments
: you should know that when the receiver is switched on,
for two seconds, the position taken by the receiver corresponds to the position of sticks / switches / trims and other
related functions are the one received at the "Bind" (buddy) transceiver receiver. Once the helicopter fully setup
including the gyro, we recommend you to make a new binding with throttle hold (or throttle cut), enabled, all sticks
on neutral or if you do not have throttle hold available, just put the throttle stick to zero ( bottom), make sure gyro
gain is at least 30% in Tail Lock mode and rebind
. This will be your power up / failsafe values.
