Any idea what is causing this I also notice when a do like a pitch pump motor 1 right front seems like it speeds up before the other ones and tilts the quad to the back left for a second.

Hello,

Be sure your ESC all have the same exact settings. Be sure you have calibrated them one at a time connected to your RX exactly the same. Also, be sure you have reset level flight, reset gyros and re-run the RX Wizard with all trims centered.

I love my eagle trees. I have bought 6 of them total and only lost one in a quad I put together because I ventured out too far beyond my battery capability. Yesterday I had an error message as follows - "ESC Saturation" during a flight on my quad. I use 2010 1080 kv motors with 20 amp gemfan esc's. Thanks

Hello,

Please see section "9 Notification Messages" in the manual. It explains all error/notification messages, including this one.

ok. i must have missed it in the manual. Sir. One more thing please. I started to build my own quads and install your ET gear. I started out as a flying wing guy. Now everything is working fine except for one thing. I have serious pitch ocsillations at times on the quad. I am not a racer but more of a sight seer with the quads. It rocks back and forth almost spinning out of control. I can't go very fast due to this issue as well. It seems to me to be a gain issue of some sort? I am using cheap gem fan 20 amp escs. They are not programmable. I do plan on using readymaderc blheli 20 am opto escs. Thanks

Thanks. OK I read up on PID gain settings and have a pretty good grip. So the tutorial was helpful. I am not a racer quad guy but more of sight seeing flyer. So most gain adjustments in the tutorial are geared to more aggressive maneuvers. But if I understand correctly my pitch oscillations could be due too much Proportional outer and inner gain? The Vector default is at 30 in both fields. So perhaps I could start by lowering this number? Thanks

i would certainly try lower gains but then it might get to soft and mushy to control. props/ motors balanced? to much vibe on the vector?

I think my props are the problem - 10x5 Slow Flight props. It only acts up when I get a little forward speed and on windy days. Maybe I have too much prop. Now it will hover all day long in loiter on windy days but as soon as I start moving it around it starts to act up almost flipping backwards.

I'm having a problem with Yaw. in 3-D or Acro rate mode the pitch and roll are fine. I tried increasing and decreasing the yaw i and d setting and the rate for yaw with no success. Yaw overshoots and bounces back when I turn it. this is generally a problem with the derivative. But since the vector doesn't have the derivative for yaw on the flight controller I'm at a loss on how to correct it. I had this issue on my naze32 and once I adjusted the derivative on the yaw it corrected the bounce back. not sure how to fix it on the vector

The latest beta firmware added Integral and Derivative functions for yaw.

Hey guys this is a great tutorial! Is there anything similar that would be more applicable to tuning a QAV500 in 2d and 2d+ and also getting loiter dialled in?

Hello,

The tuning procedure for a larger frame is the same as described in this tutorial. As for loiter, we recommend assigning a knob to Position Hold Gain and then Braking Aggressiveness, adjusting as needed.

Thanks very much. I got her flying great! Far better than my pixhawk ever was.
