Demon 3sx tail servo works in reverse
I flew my turbine synergy for the first time today and I noticed that although my tail servo shows the correct movement in the diagnostic page, the gyro moves it in the opposite direction. In order to get it work right, I had to reverse the servo on my radio and then switch direction on the demon set up. So now the helicopter flies fine, but the diagnostic page shows the servo moving in the wrong direction. (stick left...nose left, stick right...nose right). Everything works fine, and it flies fine, is this something that should worry me?

That looks like the normal and correct mode...

Well as I mentioned, the tail moves in the correct direction now both with the gyro and from the transmitter (flies great, flying the nose), the only question is that the diagnostic page shows the tail servo moving the wrong way.Team Synergy, Team Scorpion, No good deed goes unpunished

Because you likely forgot to set the correct direction on the software, (Mixer page). You can correct it in the radio, but I'm not sure if that will mess up the rescue.

Santiago, I did set the direction on the mixer page in the software which allowed the transmitter to move the tail in the correct direction, but the gyro worked backward. I had to reverse the radio direction and then reverse the it again in the mixer page.Team Synergy, Team Scorpion, No good deed goes unpunished

There are two things to reverse in the mixer page, control (servo) direction and gyro sensing direction. I know you are not new to this but if one was backwards when you did your preflight, it means one of the two was set backwards on the software.

Is ok, I've done the TX correction before on an overnight rebuild at 3am, although I scratched my head as to why. It flew ok.

I later found out what changed that triggered me to reverse the tail servo on the TX. I redid the setup later to zero everything.

HEY, If Is flying right leave it alone

PS
Thank God you do preflight checks! Wish everyone did.

I went back and checked it again. In the diagnostic page it says to switch the servo direction on the radio to show correct left and right. Then when you go to the mixer page there is one setting to change directin which says it is for tail servo AND gyro to have the tail servo move in the correct direction. So when I hit this, now the diagnostic page shows correct and the servo moves correct, but the gyro moves backward. If I flip it the other way, the gyro moves correct but the servo moves backward.Team Synergy, Team Scorpion, No good deed goes unpunished

Congratulations on the maiden flight!

I know this is a long shot, but, not sure what tail servo you're using, but if it's a programmable servo, is there any chance it's reversed in the servo's programmable settings?

The tail servo is a MKS HBL 980HV. I don't think is programable.Team Synergy, Team Scorpion, No good deed goes unpunished
