Questions about Dji F450 Naza Settings

[Pozzix]

Hi guys,

after building f450 w Naza and after 40 test flight, I'd like to submit to you some questions:

• how suppose to change Basic gains when props changed?

1. • My setting with Graupner 9x5 are: 138 Pitch/Roll 120 Yaw and 130 Vertical
   • Attitude gains are 140 on both

All is good and very stable, also in GPS mode (position is locked in both axis). However I notice some oscillating when lower TH to descend from high altitude. Is it normal or I have to change vertical gain? Frame seem well balanced (I used a small cylinder below frame to identify correct CG, with all stuff installed and ready to fly.

• If I install new props, like Graupner 10x5 how should change basic Gains? I do some test today and these seems near setting with 9x5 props. IMHO I suppose that gains have to increased, due to major power. Maybe
  I'm wrong?

Other things:
Why in Naza Assistant I can't insert decimal values in mounting tab, to increase accuracy of GPS position respect COG?

What is the relationship between Attitude Gains and (D/R) Expo on Tx? Maybe I'm wrong but reaction speed settings of these gains seems to me like D/R on TX.

Last question:


for correct motors balance, is better to balance every motor in its arm apart, with frame not assembled (and certainly without props), or is there a method to balance every motor within mounted frame?


Thk for any help.


However, this quad is a.m.a.z.i.n.g. and I'm very abducted.

Sorry your being ignored. I'm new to the F450 but my quad was configured by dealer with 10" props. I tried the 8" without any software modification and it flew differently but still rock solid. I do like the 10" better....BTW: I'm using a 3 cell 2200 lipo.
