GY48V installation on helicopter:
When installation the GY48V on helicopter, please use double sided
sponge tape included. Make sure the bottom of gyro is perpendicular
to the main shaft of helicopter. Otherwise it will effect the direction in
roll and pitch.
90
。
When installing the GY48V to electric helicopter, please make the
distance to motor not less than 10cm to avoid interference.
GYRO Connection:
Connect to receiver sensitivity channel
Connect to receiver rudder channel
Connect to rudder servo
Servo selection:
Head lock function of gyro has close relations with the function of the tail servo you use, the effect will be
more precise if a digital servo is used.it’s recommended that you use a digital servo etc. When
using a digital servo as the tail servo, please set the DS mode switch to the ON position. While using
a normal one, please set it to the OFF position.
NOTE: if using a normal servo, set the DS switch to the ON position instead, the rudder may be destroyed.
Check gyro operation direction:
Lift the helicopter, vibrate its head to the left.(if the tail servo moves to the left when the tail servo linkage
rod of the transmitter moves to the same direction, the gyro direction is correct.) If the direction is not
correct, please switch the direction switch.
If operation direction of gyro is designed wrong, danger of high speed rotation will arise while helicopter
begins to fly. Please make sure gyro operation direction is correct again and again before each flight !
Adjust maximum travel of tail rudder servo:
Move the rudder stick to the left and right, and adjust the limit trimmer so that the servo operating angle
does not strike the linkage. During flight, the servo will not operate beyond this limit and the linkage will
be protected. If the setting is too low, the gyro performance will be affected.
AVCS mode adjustment:
If using digital servo, please set delay time trimmer to the position of “0”, while using normal servo, please
adjust the delay volume according to the detailed fact.
