Atti or GPS on take off

[thewhittys]

Hi All

Hope you all had a good Christmas and wishing you a Happy New Year.

well i think i am ready to give my F550 its first flight. I';ve been having great fun with a Hubsan X4 and seem to have that mastered so going to try a small flight.

Just a quick question. Do i take off in Atti mode then once in the air change to GPS?

I thought i had read on here that you do not take off in GPS mode but cannot find the post now

Any help on my first flight would be appreciated

Cheers

I have no problems taking off in GPS mode. Do it on both F450, F330 and the TBS clone

Either, sometimes manual if I forget to change it

GPS is fine as long as you have a good lock.

i would certainly get used to taking off and flying in Atti mode, GPS is something to use as a feature, safety net, but just my opinion, should not be relied on as a general flight mode.

But, there is no reason you cant take off in GPS mode, but i do prefer to take off in Attitude mode after its locked home point, never take off if it has not locked its home point.

To confirm a home lock, flip the IOC switch about 4/6 times until you see rapid green flashes.

Are you sure that confirms home point ? i thought that was setting the position for POI not home point ?

yes I';m positive, it sets the home point manually.

Ok thanks for all your advice

[Friskle]

right, something i never seemed to need to do lol

I always do it, second nature now

Something worth knowing.  Naza will set home point wherever it attains a suitable GPS lock.  That may not be your point of lift off if you';ve plugged the battery in and then walked it across to where you want to launch from.  That can catch some out.  So its either worth getting into the routine of plugging the battery in at lift off point or setting the home point manually before arming.

I always do the former - even before I learned of this "feature" ::)

[thewhittys]

Thanks HandsOn didnt think of that.

Just as a side, i do not have an IOC switch as in one of my previous posts i cannot set up the IOC switches in the Naza assistant

[Friskle]

If you cant, you dont need to, just always from connecting the battery, wait and be patient, until you get a succession of fast green flashes.

i dont know how many channels you have, but you would need connections to X1 and X2

Hi Friskle

I have 8ch turnigy 9xr with a spektrum AR10000 rx. I followed all the wires for my other post and they are wired like this

Now i can see better i can see that the lead from the x3 to the x3 on the pmu has been connected to another lead (white join in pic). This other lead goes to the battery slot on the receiver??

Followed all the wires now as below

Aux 1 on RX to X1 Naza
Aux 2  to X2
Aux 3 to IOSD
Gear to U

Hi All

Well I';ve finally had my maiden flight all be it only round the garden at about 10ft. All went well apart from 1 question.

I tested Atti and GPS mode and seemed ok. In GPS mode drone stayed virtually still. Flew it away from me in GPS mode and flicked the failsafe switch. Drone shot up over house height so i panicked and went back to Atti mode brought it down safely.

Did it do that because it was only 10ft off the ground or have i set something wrong in the Naza

Cheers

The reason it shot up is because thats the height defined in the failsafe settings for return to home, this is to avoid hitting building and trees when a failsafe happens. As regards to the best mode to take off in I believe thats completely up to you as I don';t think Naza will arm without a GPS fix.

[thewhittys]

Thanks Paul

I just wanted to get it off the ground as it was my first ever flight so was a panic when it shot up in the air :)

Cheers

yes, return altitude will be reached before naza moves. vector will not take off in GPS unless told to do so in the settings, but naza doesn';t mind which mode.
