I have the Trex450x and am having a little issue with the tail control.

It's not a huge issue, but when I have the Gyro in HH is seems to over-correct when stopping any movement. Let me explain a little better. Just hovering it seems to hold pretty good, but if I turn either way, as soon as I let off the control, it moves the other way a few inches then back to stable. I can even make it do this without the main blades spinning. So I move the stick a little and can see the pitch change, but when I release it move a little the other way before centering.

Is this right? Is there a way to minimize this correction?

I'm using the Gy401 and have it set at HH 50% right now. I'm using a Hitec 50 server on the tail. I have playing with the delay and the gyro gain to try and fix this, but I can't seem to effect it that much.

Just in case you need to know.
Futaba 7CHP
Electron 6 Receiver
Mega 16/15/3
CC35 ESC
Hitec 56hb main servos
Hitec 50 tail servo
Ball link upgrade on servo links

I had a wreck recently (I won't get into flying at night and losing it in the dark and crash landing from about 30' on pavement), but I've completely rebuilt the tail, and main shaft. Everything is ballanced and trimmed.

The Trex still flies great, but this is just a little annoying.

Let me know if this is normal and/or a stupid question.

Also, can someone explain tail hunting? I just want to make sure I understand the terminology since I'm fairly new to Helis.

Thanks.

Morning,

Lower your Gyro HH gain.

If he lowers his Gyro gain below 50% it will not be in HH mode. I never tried the Gy401 gyro but try setting it up higher then 65% and see if that fixes it.

Yeah my transmitter (futaba 7chp) controls the gyro. It has 0-100% for regular and 0-100% HH. I'll try that and see what happens.

Thanks

Thats weird. I have a Hitec eclipse7 XR and a jr g500t gyro and have 0 instructions to speak of. It seems that 50% is no gyro. 0 to 49% is regular and 51% to 100% is HH. The extreamities is the greater gains.I guess its like my first girlfriend told me. Thats just the way it smells.

Are you sure you're not doing the mistake I first did when fresh with my JR PCM 9x on a 6 ch receiver.
I tried and tried adjusting gyro gain on the radio menu untill I realised I was adjusting it on aux2, which is the seventh channel, a channel my receiver wasn't reading. As I started adjusting things on channel 5/gear where the gyro was plugged in things got a lot better....

If rate/HH is resp 0-50 and 50-100 or 0-100 depends on the radio. On the gear channel on my JR I adjust between 0 and 100 in position 0 and 1. 0 is HH for me and 1 is rate.

The way the percentage arranged on the different TX are not always the same, so as long as you have the solid red LED on the 410, you are on the HH mode. And yes, it will act like you saw if you happen to change the position of the heli from what the gyro memorized, which mean even after you let go the rudder stick, the rudder servo will keep moving until it finds the memorized spot. This is how thw HH works. As for the gain setting, increase the value until the tail starts to wag, then turn it down a bit (do this with the highest possible head speed you plan to fly).

Try this, turn on the TX with the HH mode set to ON, then connect the battery on the Trex. Make sure you get the steady RED on the 410, then turn the Trex 180 degree and start to lift off. The 410 will try to turn it back to where you set it at first because it doesn't know whether you or the wind turned the Trex around.

I use the Futaba 9Z and set the gyro at only 25% for HH mode because if I set it over 35% it will hunt (tail wagging). I normally set the delay at min or NO delay at all.
