Noob with Rudder Calibration Issue - Naza F450

[Steveor]

After an arduous weekend at the computer trying to get my Naza F450 set up I finally got it airborne. But I'm having rudder issues in Attitude mode. My quad is a stock F450 with 8" props, my gains are at default, Tx is a Turnigy 9x. The quad floated up nicely but then kept rotating. I saw that it was an obvious rudder issue. When I connected the quad to Assistant the rudder's rest position indicated it was way to the left. I recalibrated, flew again, same rotation issue. Hooked up quad to Assistant and I need to recalibrate as the rudder way to the left again. A forum search did not clear this issue up for me. If anyone has dealt with this and can provide assistance I'd really appreciate it.
Thanks, Steve

all i can think of is the obvious about trim or subtrim. And to ensure u are not using any mixes that affect rudder. Are you in heli mode or acro on the tx?

 

[Steveor]

I'm in acro mode ion the Tx. On my display my trims are all at zero. On my menu items my sub trim settings are in the zeros but my trim setting reads 001<-002> (I don't know what that means). I don't know what you mean about mixes affecting rudder.
Thanks, Steve

no worrys on the mixes since you are in acro. can you snap a picture looking down on the naza and post it up... just to see that all is pointing in the right direction.

mhm, did you forgot to "write" the Tx Calibration before you unplug the USB Cable?

Nope. But I will now. What does that do?

My set up below. I see that my MC is a few degrees off from front to back; I'll adjust that. I also moved my Rx wires further away from the battery cables (does an electric current affect the wire signals?). On my last check ride my rudder stayed calibrated. So maybe I solved the issue.

I'm glad these props can take a beating.

Duh! Should've read the manual more closely.

My quad is flying pretty reliably now but it is kind of jerky and I hear the engines kind of rev in hover. So I'll have to learn how to adjust my gains. Thanks.
