Again, watch the LED to confirm which mode the gyro is in before making adjustments. Terms of Use Privacy Policy. The best position for tail centering is to adjust the rudder link so that you have 4.

Team Futaba Tip #2

It should move the servo clockwise which thereby should pull the rudder control link forward. Use care here; small increases can make large changes pirouette rate.

Once ideal trim is obtained, land the model. The gyro channel reverse setting in the radio can be used if you want the switch in the opposite direction it currently is in just depends on if you want gh401 switch up or down all the time.

The distinction is important to recognize as the proper use of the AFR function will ensure no drifting problems occur with the gyro. Hold the tail rotor stick full right and pull the control rod all the way forward. With the GY there is very little reason to use standard rate mode.

If it’s not, turn the link clockwise to move it toward the back or counter clockwise to move it forward. Move the rudder stick to the right, then back to center, if the rudder servo does the same then you are in normal mode which is wrong.

Check the servo direction. On my gy that came with the servo I have found 84 is what it took.

The Futaba GY401 Gyro

Connect the one with 3 to the rudder channel of the manua labeled ‘Rudd’. Then turn off the receiver and then back on and let the gyro initialize in heading hold mode. You may want it faster or slower so change the value appropiately. Also keep your tail shaft oiled. The large range of heli size usage and outstanding performance is why the GY outsold every other performance gyro on the market.


One side controls heading hold gain; the other side controls rate gain. Proper trim can and should be obtained mechanically by adjusting the tail rotor pushrod.

Gy410 technique for greatest tail rotor servo life should be to run as much gain as needed for the most demanding maneuver and no manhal. The ball on the rudder servo is too far away from the center.

Even the best maanual analog and digital servos that Futaba produces pale in comparison to the performance achieved when the gyro is paired with the or servo tail rotor servo. Now that you have the gyro initialized correctly, flip the GEAR switch. The helicopter is out of balance.

Adjust the guides to acheive the least resistance. The helicopter model and engine must be running smoothly. Use the ‘clear’ button to set the values to zero. Are you considering getting an Esky V2 micro heli? If it is dry and tacky this will cause the problem. Pull the link as far forward as it can go then adjust the ‘Limit’ control on the top of the gyro so that ,anual ball on the servo arm centers with yg401 link.

Check and double-check this point, because getting it backwards can cause needless excitement on a model’s first flight. You mahual to start up this gyro in heading hold mode. With transmitter and receiver turned on, watch the red LED on the gyro after the gyro initializes. Speaking of manuall, the came in two different packages.

Observing the ATV screen in the radio for the gain select channel will allow the user to determine which is which. Do not use manal rudder ATV for this purpose. On other gyros I would prefer to have Normal flight mode use standard rate because the HH mode would have a kinda jerky non-fluid motion when doing ground maneuvers such as slow piroueting circles.


Next disconnect the rudder link from the servo. Next set the rudder servo arm so that it points straight up with the rudder stick and rudder trim centered. You cannot use this to prevent linkage binding. The GY followed the progress gyy401 that alone offered some nice value if you didn’t want to have to purchase another gyro for your next bird.

The signal side will be opposite of the black ground side. Those pilots wishing to use rate or normal can adjust that gain in gyy401 same manner as for AVCS, though the gain select switch will be thrown in the opposite direction than for AVCS. Make sure the guides are aligned for least resistance. Using the limit trimmer pot on the gyro, adjust the tail rotor travel as needed for no binding at extremes of throw.

Move the rudder stick to the right and watch the servo arm. Next check that the front link is centered with the ball on the servo arm. Some of these options are more confusing than others, sometimes confusing kanual newcomer and making him or her feel the gyro is a great deal more complicated to set-up than it ever has to be.

Yes, the tape that comes with the gyro is not very cushiony, but that’s the way it needs manua, be. This will make the nose of the helicopter rotate to the right.

It avoids the use of any preprogrammed gyro software, because many months of following posts and questions on the various web forums has proven that those software menus sometimes produce more confusion than the set up about to be detailed. Remember that a few hundred rpm mwnual on the head is several hundred rpm drop on the tail. This adjustment only effects how fast the tail moves your pirouette rate.
