OK, so I've got my NAZA flying, and even in this AWFUL strong wind, 30MPH today, it holds position, however, there are one or two niggles I want to get ironed out.
What gains do people use on their NAZA with an F450 frame?
I've got an F450, GPS module and 10" props (groupner)
When I try to take off I notice that I need to give almost 60% throttle to get it off the ground, is this normal? My other quads take off with far less. And then I find it seriously yo-yos.
Any pointers would be most appreciated!
Cheers,

I've found that generally under 50% = decent and above 50% = climb.. 1/2 stick = hold.
Yea the controller is designed that @ 50% midstick it stays at the same altitude (so it wont lift off) so 60% stick you should see it lift i usually just go straight to 80% ish and it takes of nicely
F450 Quad Settings (using f450 frame and standard props and motors)
135 135 125 130 Basic Gains
135 135 Attitude
These are from the quadcopters site but I remember them working quite well.
Setup a throttle hold at 50%
For atti hold.
When I swapped to graupner props I found it did need more throttle to get it up in the air over the standard ones. Defo not as much lift there.
I have got a new set if standard ones and am going back to them for a bit I think.
When you say YOYO what do you mean? It's oscillating alot in a hover? Almost like it's fighting itself? Your gains are too high in that case.
Yup agree the graupners provide less lift and need alot more rpm for hover, im goibg back to the stock props
Is there any mileage in getting Graupners with a greater pitch?
3S or 4S? I find 10" Graupners give plenty of lift on 4S (gets em spinning a good bit faster). My Disco is a lardy 1.8KG and has plenty of speed and lift, pulls 50A in manual or FFF
IMO - faster RPMs and less pitch = more gyro effect and less affected by gusts so smoother FPVing (tradeoff is efficiency and bit less flight time)
Was the yo-yoing slow and bobbing or more of a fast shaking?
For slow bobbing try increasing gains by about 10%
For fast shaking (usually noticable under FFF or full climb rate) decrease gains by a small amount until it smooths out.
In ATTI or GPS ATTI, altitude hold will always be 50% throttle, regardless of craft weight, motors, props, etc (within the limits of the craft) Naza will regulate the actual throttle percentage sent to the ESCs to compensate for load.
I fly 3s not tried 4s yet but happy with power on stock props,
So, I've got an F550 Naza-Lite + GPS
Does anyone know what the best gain settings are for this?
Many thanks!

That's the magic question Keukpa. I've still yet to get some decent settings for my 550
It should fly reasonably well out of the box if its not look at your CG and check you've got no harsh vibrations ...
Your props ballanced, using fast esc's and done the naza dance?
I've now built 6 naza/dji setups and all but one (iffy bulkets) have flown good out if the box :)
Thanks Davey, I'll check for bad connections and vibes, but done the calibration of GPS and NAZA, and CG looks ok!
I'll have to have a little more of a play tomorrow! :)

Some gain settings Ive seen posted on another forum, I think I tried these and found them twitchy:-
150 150 175 150 80 80
Thats with 2x 3300 mah 4S lipos apparently and 10x5 Eprops

Found a picture I did from my setting before the upgrade software so I will have put them back in
165 165 125 130 110 110
What I was flying with I don't know but I had X1 to change the 165 165
I always found that the wind would blow it about, Last time we was up at the field there was not to no wind and it was fine but like I say I change the setting on my TX up or down and see for that day.

Definitely got the right settings for your compass position? i.e. a minus number for the Z axis? A lot of people put in a positive number and it makes it fly like a brick.

I believe so! I did have the X,Y wrong way round, usually X is the horizontal axis and Y the vertical, but it appears that have it the other way round. So I sorted that. And triple checked it all. I believe it 'might' be gains.
My current gains are:
Pitch - 140%
Roll - 135%
Yaw - 130%
Vertical - 130%
Attitude Pitch - 140$
Attitude Roll - 130%

Good point Blackout....well to that end, I have tried several different gains and also put X2 as gain control so I can adjust them during flight....
nothing has made any difference, so I am going to try a different RX, why? Because I am currently using an FrSky D4FR, I am using PPM, so only one channel connected to the NAZA.... dunno if it will be the cause, but who knows....
Here is my setup:
DJI Hex F550 Frame
DJI 2212/920KV motors
OPTO 30A ESCs
NAZA-M Lite w/GPS
3S1P 5000mAh Battery
10x3.8 Props....
Hope someone can help here, doing my nut in!
