Please help (Pd: Sorry for the google translate) ... I installed Lightbridge, my Dji Phantom drops slightly only when full accelerated or retreat to recover after falling up ... I tried to modify the gains Vertical, Attitude Pitch and Attitude Roll, and no change, still the same ... NEVER HAS BEEN fall or crash.
My gain:
125% Basic Pitch Yaw Roll 125% 140% 120% Vertical / Pitch Attitude Roll 260% 260%
My setup:
Dji Phantom 2 with Naza M 2 (updated to the latest version 3.14)
Zenmuse H3-3D (updated to the latest version)
GoPro 4
Lightbridge (updated to the latest version)
original battery (new updated)
This did not happen before with my fpv analog system (with Lightbridge my phantom gained weight 37gr)

Usually increasing the vertical gain will help.

As DWA suggested, vertical gain will need adjusting after adding weight to the Phantom, my V+ in NAZA default is 140%, I would try it in 10% increments until it recovers to a hover normally.

Nothing has changed... tested Vertical gain to 150, 160, 170, 190, 220 and nothing... Maybe need more powerful motors?

Motors are fine, if it has enough power to take off it has enough to hover.
Vertical gains should have made a difference, that's what they are for. Are you sure the new values have been saved ? Shutting down the assistant and opening again to look at the gains should confirm the changes.

Totally confirmed.

I just updated the Naza from 3.12 to 3.14 at the same time when installed the Lightbridge... Maybe its a bug of the update? Can i downgrade to 3.12?

Any relationship with this???? http://forum.dji.com/thread-14965-1-1.html
