This value rarely causes the tail to “hunt” on first hovering flights.

If the servo moves to one direction but does not move back to center then you are in heading hold mode which is right. Its simple yy401 and solid performance characteristics have made it a hands down favorite among many sport helicopter pilots. The signal side will be opposite of the black ground side. Check the blades, check for bent main shaft, spindle shaft, tail shaft, out of balance tail blades, etc.

Further adjustments are rarely needed as most pilot fly in ACVS mode all the time.

It should move the servo clockwise which thereby should pull the rudder control link forward. Do not disturb the trim in the radio. Set the tail lever so that an imaginary line mznual from the two screws is parallel to the tail shaft.

Quick Start Guide for the GY401

On a Futaba receiver, this is channel number 4. This will set how fast the helicopter rotates. Notice that the values are different, you do not need as much to rotate the helicopter to the left because it is going ‘with’ the torque in that direction. One direction will set the gain value for heading hold and the other will be for standard gy41.

The best position for tail centering is to adjust the rudder link so that you have 4. A wheel with a hole drilled for the ball joint is preferred g401 a “star” arm because of greater rigidity. The tail rotor servo is plugged into the output lead from the gyro. Without a doubt, the GY gyro with or servo is one of the best tail rotor stabilization systems produced to date.

Futaba GY Gyro How-to

This is very simple, gy4001 special here, just connect the rudder servo to the female connector. Check and double-check this point, because getting it backwards can cause needless excitement on a model’s first flight.

This value will mahual a mild pirouette rate that can then be increased to suit the taste of the pilot. Also make sure the trims are centered. It has been perfectly matched to operate with the GY in fast digital mode. 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.

It’s also important that your engine is running good. As mentioned, the GY supported both slower analog tail rotor servo pulse rates or can be switched to a Hz high frequency rate for fast tail rotor specific digital servos.

Next disconnect the rudder link from the servo. The tape works great, use it.

The Futaba GY Gyro

Wait 4 seconds for the gyro to initialize. If you the tail wags in a hover then decrease the gain. The first thing to do is make the link slide as free as possible. Next check that the front link is centered with the ball on the servo arm. The cushioning is done inside the gyro. The GY worked well in almost every single rotor bird out there from size electrics up to 52cc gas or MW54 powered mannual monsters with rotor diameters approaching 2 meters.

In the old days, we ran as much gain as possible without having the tail “hunt” or “wag”.

Manual GY401

Yes, the tape that comes with the gyro is not very cushiony, but that’s the way it needs to be. If it’s not, turn the link clockwise to move it toward the back or counter clockwise to move it forward.

The model should now hover with no drift. Use the ‘clear’ button to set the values to zero. Next set the rudder servo arm so that it points straight up with the rudder stick and rudder trim centered. To select both sides flip the GEAR switch.

On most helicopters, a servo wheel with ball joint mounting radius of My RC Helicopter eBooks are here to help maunal with those exact problems.
