Anybody know how to setup a gy401 with a futaba 6ex 2.4ghz radio?
Okay here is the problem. I got the Titan setup for flight, but I am having problems with the rudder. When the heli starts to lift the tail will shake back and forth in a very fast manner. I am assuming my gy401, the radio, or both are not setup correctly. I am using a futaba 9257 digital servo to control the tail. A friend said I may have gyro reversed?? I don't know what he means. I have the limit turned down to zero, and the delay at zero. I am totally lost on what to do.

i have the delay set to 0 but the limit to 110 have this gyro and a hitec digital tail servo but with a jr 9x2. also you need to make sure your gain settings arnt to high as this could cause a big wagging

It wont work all with the limit set to 0 but I don't think you can actually set the limit to 0.

Put the gyro in rate mode and adjust the limit until you get max throw with no binding with the rudder end points at 100/100. If you can't get the limit pot around 100 then move your linkage in one hole on the servo arm.

Then adjust the rudder end points (up or down) for your desired piro rate.

How are you setting the gain? Tail wag like that is generally too much gyro gain.

The problem is that I'm not for sure on what to do. I the gyro gain setup by using the radio? I'm kinda brand new at this heli stuff. The manuel for the radio, in my opinion, is pretty lacking as to giving examples.Fly till You Die; or till You Totally Destroy It

yes you need to plug the red wire (the one with the single yellow wire on it) into the gyro gain channel of your radio. this usually then needs activated on the radio. then you set up the switch that activated the gain. on my radio with the switch pushed back that pos 0 and i have that at 75% (this is heading hold) and then with the switch pulled forward (pos 1) its set at 25% (not heading hold) it sounds like you havnt set this up and therefore no or too much gain set in the gyro

There is a signal gain wire that is a servo connector with a single wire on it (red connector w/ white wire typically). That goes to channel 5. That single wire will align w/ the servo signal wires (other white wires if you have futaba servos).

The servo output that your Rx puts onto channel 5 determines the gain.
I have mine set up as the gear channel (channel 5).
Travel adjust (ATV) for the switch (one adjustment for each side of the switch position) determines gain.

you can tell if you are in Rate mode because when you move your rudder stick it will return to center immediatly. In HH mode it will stick to one side then very slowly return to center for a 401.

If you have your gain channel plugged in, set your Travel adjust for both sides of the CH 5 to about 50% and start there.
