This gyro initializes fast, only about 3 or 4 seconds. This value may be well below the point of “hunting”, but that is just fine. My most popular eBook! To get the two Futaba connectors into your Spektrum receiver you will have to trim the flat piece that sticks out on the side.
Do not disturb the rudder. Move the rudder stick to the right and watch the servo arm. On most helicopters, a servo wheel with ball joint mqnual radius of If your engine loads up a lot then you won’t be able to keep a consistent RPM.
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.
Futaba GY Gyro How-to
It is said that copying someone or something is the highest form of flattery; guess that is mnaual there was a cheap GY clone hitting the market almost every month back then. The ATV for the gain select channel has two sides.
The distinction is important to recognize as the proper use of the AFR function will ensure no drifting problems occur with the gyro. Adjust the guides to acheive the least resistance. The Esky F V2 is an inexpensive and cool little scale Airwolf heli that is easy to fly.
The large gy4401 of heli size usage and outstanding performance is why the GY outsold every other performance gyro on the market.
Use the ‘clear’ button to set the values to zero. Continue with the next step to determine if it’s in the right mode. 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. The instructions that come with the gyro are good, but they offer several options for set-up.
Before we continue it helps to understand the characteristics of this gyro. Do not disturb the trim in the radio. The GY worked well in almost every single rotor bird out there from size electrics up to 52cc gas or MW54 powered turbine monsters with rotor diameters approaching 2 meters.
The Futaba GY401 Gyro
You may want it faster or slower so change the value appropiately. Now that you have the gyro initialized correctly, flip the GEAR switch.
Tail wags only right after msnual pirouette, or anytime I move the tail then stop. This is very simple, nothing special maual, just connect the rudder servo to the female connector. Using the limit trimmer pot on the gyro, adjust the tail rotor travel as needed for no binding at extremes of throw. Ask 5 RC helicopter enthusiasts what the best solid state mankal lock gyro was when they first came out, and 4 of them will maual say the GY Wait 4 seconds for the gyro to initialize.
To get the tail to move faster or slower, adjust the rudder channel travel. I also use a JR Ball link resizing tool to remove unecessary resistance from the ball links. Confirm that no sub-trim or ATV is present in the transmitter in any flight condition on the rudder channel.
Inhibit all preprogrammed gyro software in the transmitter. For this setup we will not use the built-in gyro function. You cannot use this to prevent linkage binding. On a Futaba receiver, this is channel number 4. The Futaba GY had a built in Limit Trimmer adjustment so you can set the amount of tail rotor servo travel to avoid servo over travel and stress on the servo. It should move the servo clockwise which thereby should pull the rudder control link forward.
On my mnaual that came with the servo I have found 84 is what it took. This will make the gyro go into standard rate mode. The GY followed the progress and 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. This value rarely causes the tail to “hunt” on first hovering flights. If it’s not, turn the link clockwise to move it toward the back or counter clockwise to move it forward. I did this so as to stop the resistance the rod had on the front manua guide due to being pulled down to the servo.
I know many people who started with a Futaba GY gyro in a small size electric knowing one day they wanted to get into a larger electric or nitro powered heli. Rotate the helicopter hy401 the nose goes to the left and watch the rudder servo. What follows is ONE example for setting up the GY gyro that works for virtually any model and almost any brand of radio.
If so, my in depth review should help you decide before throwing ggy401 money down.
The helicopter is out of balance. The RPM’s janual be to for 3D flight. Without a doubt, the GY gyro with or servo is one of the best tail rotor stabilization systems produced to date.
