Build V2 Carnage 3.5"

Hi Husafreak,

Just my 2 cents worth.

Very first thing, be sure to back up the default Betaflight settings. At the
very least a DUMP ALL and a DIFF ALL. 

Consider taking a few test flights with the default tune, before you change
anything. Each build is a bit different, so until you know how it flies with
the default settings, what characteristic would you be trying to "fix" or
"tune". Maybe, fly it first, see how it flies. 

Here is a scenario that I keep seeing. Someone builds a quad, maybe 
their first. Next, they fiddle with all sorts of tuning, PID settings, ESC
settings, and who knows what else. Ok, fine. Then they take the quad
out for a flight and is flies horrible if at all. Now, they ask, what is wrong;
how do I fix this or that. 

My concept is to assemble the craft, do a very basic Betaflight configuration
which is mostly setting up the ARM and Fly Mode switches and maybe a bit
of OSD adjustment leaving all of the tune just as it came. Next, I fly the
craft. First, a simple take off and hover at about 4 feet and very slight stick
movements just to confirm that the controls seem to work. Next, I move 
outside for a few LOS test flights to get an idea how the quad responds 
to stick movement. At this point, I know that I have something that will
at least fly. Except for one build, my quads are running on the default
(stock) tune and PID settings. Since they fly just fine, I see no reason to
mess with the tune: If it ain't broke, Then DON'T fix it. 

I have a 4" build, my Katana-LR4, running the same BH motors and 
pretty much the same specs and an all stock, default, tune and she flies 
just fine. My suggestion would be to fly it before you start changing things.

Just me.
